CCQQFAR Portal de Primer Ingreso

CCQQFAR requires two specific tests for first-entry applicants: a Prueba de Habilidades and a Prueba de Ciencias Naturales y Exactas covering Química General, Biología, Física and Matemáticas. Both must be approved before the faculty issues the Constancia de Aprobación, which is valid for two years. Assignment is handled online through the faculty's first-entry portal within a single published window per opportunity, and the Ciencias test is delivered on the faculty's online evaluation platform at a fixed start time. Sitting the tests is free under artículo 55 del Reglamento del SUN. The official tests are administered in Spanish; this 100-question bank is an English-language MCQ study adaptation of the published Anexo 1 content outline, not an official translation or a substitute for faculty registration.

Sample CCQQFAR Pruebas Específicas Practice Questions

Try these sample questions to review concepts for the CCQQFAR Pruebas Específicas exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which laboratory separation technique is most appropriate for separating a homogeneous mixture of two miscible liquids that have significantly different boiling points (e.g., water and ethanol)?

A.Gravity filtration

B.Centrifugation

C.Liquid-liquid decantation

D.Fractional or simple distillation

Explanation: Distillation exploits differences in the boiling points (volatilities) of miscible liquids in a homogeneous solution. The component with the lower boiling point vaporizes first, passes through a condenser, and is collected as distillate, leaving the less volatile component behind.

2Chapter 1 of the chemistry reference listed in the CCQQFAR guide covers the scientific method. Which sequence correctly orders the stages of a controlled chemical investigation?

A.Observation and data collection → formulation of a hypothesis → controlled experimentation → analysis → statement of a law or theory

B.Formulation of a theory → observation → hypothesis → experimentation, discarding any data that contradict the theory

C.Experimentation → publication → observation → hypothesis, with the hypothesis adjusted afterwards to fit the published conclusion

D.Hypothesis → law → observation, because a scientific law must be established before any measurement is taken

Explanation: The scientific method begins with observation of a phenomenon and the collection of qualitative and quantitative data. A hypothesis is then proposed as a tentative, testable explanation and is probed by controlled experiment in which one variable is manipulated at a time. When repeated experiments support the hypothesis, the regularity may be summarised as a law (a concise, often mathematical statement of a consistent relationship) and accounted for by a theory (a unifying explanatory principle).

3What is the primary operational difference between an extensive property and an intensive property of a chemical system?

A.Intensive properties change when a substance undergoes a physical phase change, whereas extensive properties never change

B.Extensive properties depend on the quantity of matter present, whereas intensive properties are independent of sample size

C.Extensive properties can be measured without altering the chemical identity, whereas intensive properties require a chemical reaction

D.Intensive properties are always additive when combining two identical systems

Explanation: Extensive properties (such as mass, volume, total enthalpy, and heat capacity) depend directly on the amount or size of matter in the sample. Intensive properties (such as density, boiling point, refractive index, and temperature) are intrinsic to the substance and remain unchanged regardless of sample size.

4Which mixture is classified as a colloidal dispersion exhibiting the Tyndall effect rather than a true homogeneous solution?

A.Aqueous sodium chloride solution (0.9% saline)

B.Aqueous hydrochloric acid (1.0 M HCl)

C.Whole milk

D.Ethanol dissolved in water (70% rubbing alcohol)

Explanation: Whole milk is an emulsion/colloid composed of microscopic fat globules and casein protein micelles (1 to 1000 nm in diameter) suspended in an aqueous medium. These dispersed particles are large enough to scatter visible light (the Tyndall effect), making the mixture cloudy and preventing it from being a true molecular solution.

5In thin-layer chromatography (TLC) of pharmaceutical alkaloids using a polar silica gel stationary phase and a nonpolar organic mobile phase, which compound will display the highest retention factor (R_f)?

A.The most polar compound, because it binds most strongly to the polar stationary phase

B.The compound with the largest molecular weight, regardless of polarity

C.The compound that forms the strongest ionic bonds with the mobile solvent

D.The least polar (most nonpolar) compound, because it interacts preferentially with the mobile phase

Explanation: In normal-phase chromatography, the stationary phase is polar (silica gel) and the mobile phase is relatively nonpolar. Nonpolar compounds interact weakly with the polar silica and partition preferentially into the mobile phase, traveling further up the plate and yielding a higher R_f value (distance traveled by solute / distance traveled by solvent front).

6A student measures a mass of 0.0520 g on an analytical balance. How many significant figures are recorded in this measurement?

A.2

B.3

C.4

D.5

Explanation: In 0.0520 g, the leading zeros (0.0) serve only as decimal placeholders and are not significant. The digits '5' and '2', and the trailing zero following the '2' in a decimal number, are significant, yielding exactly 3 significant figures.

7Which phase change occurs with a release of heat (exothermic process) into the surroundings?

A.Condensation of steam into liquid water

B.Sublimation of dry ice

C.Fusion (melting) of ice into liquid water

D.Vaporization of liquid diethyl ether

Explanation: Condensation is an exothermic phase change in which gas molecules lose kinetic energy and form intermolecular attractions to become a liquid, releasing latent heat into the surroundings (ΔH < 0). Sublimation, fusion, and vaporization are all endothermic processes requiring an absorption of heat (ΔH > 0).

8A 4.00 L rigid cylinder holds 2.00 mol of nitrogen gas at 300 K. Using the ideal gas law PV = nRT with R = 0.0821 L·atm/(mol·K), what is the pressure inside the cylinder?

A.3.08 atm

B.24.6 atm

C.12.3 atm

D.49.3 atm

Explanation: Rearranging PV = nRT gives P = nRT / V. Substituting the values: P = (2.00 mol)(0.0821 L·atm/mol·K)(300 K) / 4.00 L = 49.26 L·atm / 4.00 L = 12.3 atm. Temperature must always be expressed in kelvin in this equation, and the value of R already fixes the pressure unit as atmospheres.

9Which set of quantum numbers (n, l, m_l, m_s) is permissible for an electron in an atom?

A.n = 2, l = 2, m_l = 0, m_s = +1/2

B.n = 3, l = 1, m_l = -2, m_s = -1/2

C.n = 3, l = 2, m_l = +1, m_s = +1

D.n = 4, l = 0, m_l = 0, m_s = +1/2

Explanation: Quantum number rules dictate: n must be a positive integer (n ≥ 1); l ranges from 0 to n - 1; m_l ranges from -l to +l; and m_s must be either +1/2 or -1/2. For n = 4, l = 0 (an s orbital), m_l = 0, and m_s = +1/2, all values are strictly valid.

10What fundamental principle states that no two electrons in the same atom can have an identical set of four quantum numbers?

A.Hund's Rule of Maximum Multiplicity

B.Pauli Exclusion Principle

C.Heisenberg Uncertainty Principle

D.Aufbau Principle

Explanation: The Pauli Exclusion Principle (Wolfgang Pauli, 1925) dictates that no two fermions (such as electrons) within an atom can possess the same quantum state, meaning they cannot share identical values for all four quantum numbers (n, l, m_l, m_s). Consequently, an individual orbital can hold a maximum of two electrons with opposing spins.

CCQQFAR Pruebas Específicas: Suggested Study Strategy

1Work from the faculty's own Anexo 1 outline rather than a generic syllabus: it names the exact chapters and reference texts for each of the four areas.

2Chemistry carries the heaviest weight. Practise limiting reagents, theoretical yield, percent composition and empirical formulas until they are automatic.

3Do not skip gases and thermochemistry: the outline names the ideal gas equation, gas stoichiometry, Dalton's law of partial pressures, kinetic molecular theory, calorimetry and enthalpies of formation.

4In physics, cover two-dimensional projectile motion and uniform circular motion as well as straight-line kinematics — the outline lists all of them, together with applications of Newton's laws to circular motion.

5In mathematics, review the geometry block explicitly named in the outline: areas and perimeters of plane figures, volumes of solids, and right-triangle trigonometry.

6In biology, memorise the ATP yields, subcellular locations, and key enzymes of glycolysis, the citric acid cycle, and oxidative phosphorylation, and review the diversity and ecology topics the outline also lists.

7Test your hardware, browser and internet connection well before your assigned Ciencias sitting, because the evaluation starts at a fixed time on the faculty platform.

Frequently Asked Questions

What are the USAC CCQQFAR Pruebas Específicas?

They are the faculty-level admission tests required by the Facultad de Ciencias Químicas y Farmacia of the Universidad de San Carlos de Guatemala for entry into any of its licenciatura degree programs: Química Farmacéutica, Química Biológica, Química, Biología, and Nutrición. The faculty configures two modules — Habilidades and Ciencias Naturales y Exactas — and both must be approved.

Which academic subjects are tested on the Ciencias Naturales y Exactas module?

The faculty's published Guía de Pruebas Específicas lists contents and bibliography for four areas: Biología (scientific investigation, characteristics of living things, water, biomolecules, the cell, the cell cycle, metabolism, cellular respiration, photosynthesis, systematics, viruses, bacteria, protists, plants, fungi, animals, evolution and ecology), Química General (following Chang's chapters on the study of change, atoms and molecules, mass relationships, gases, thermochemistry, and quantum theory), Física (precision and significant figures, vectors, kinematics in one and two dimensions, projectile and circular motion, and Newton's laws), and Matemáticas (arithmetic, algebra including quadratics, and geometry with right-triangle trigonometry).

How is the examination administered?

Assignment is completed online through the CCQQFAR first-entry portal during a single published window for each opportunity, after consulting your Número de Orientación Vocacional. The Ciencias Naturales y Exactas test is then delivered through the faculty's online evaluation platform on the published evaluation date at a fixed start time, and the Habilidades module is scheduled separately by the faculty.

Do I have to pass both tests?

Yes. The faculty's portal instructs applicants to download the Constancia de Aprobación only if both tests have been approved, and states that the constancia is valid for two years.

How much does the CCQQFAR Prueba Específica cost?

There is no charge for the specific tests. Under artículo 55 del Reglamento del Sistema de Ubicación y Nivelación (SUN), no fee may be charged for university basic or specific admission tests. The only reglamented charge in the process is the single Q70.00 Orientación Vocacional order of payment.

How long is an approval valid?

The Constancia de Aprobación issued by CCQQFAR is valid for two years, consistent with artículo 43 del Reglamento del SUN, which fixes the validity of a Prueba Específica result at two years from the date of publication.

Can I retake a test if I do not pass?

Yes. CCQQFAR configures several opportunities per module in each admission cycle and publishes the assignment window and evaluation date for each one on the first-entry portal, so an applicant who does not pass may assign to a later opportunity.

Is this practice question bank an official publication of CCQQFAR?

No. This question bank is an independent English-language MCQ study adaptation developed by OpenExamPrep from the content outline and bibliography published by CCQQFAR. The official tests are administered in Spanish by the faculty.
