1A training dataset contains photographs already labeled "cat" or "dog," and a model will use those examples to label new photographs. Which machine-learning method does this describe?
A.Supervised classification
B.Unsupervised clustering
C.Reinforcement learning
D.Data normalization
Explanation: Classification is a representative supervised-learning method. The correct labels supplied with the training photographs teach the model a boundary that it can use to classify new, unlabeled photographs.
2Which machine learning paradigm is characterized by learning optimal decision policies through trial-and-error interaction with a dynamic environment using rewards and penalties, without pre-labeled training data?
A.Reinforcement Learning
B.Supervised Classification
C.Unsupervised Clustering
D.Linear Regression
Explanation: In reinforcement learning, a system repeatedly chooses actions and learns which choices produce better rewards. The training examples do not arrive with fixed correct-answer labels.
3For the industrial Haber-Bosch synthesis of ammonia: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) with ΔH° = -92 kJ/mol (exothermic), what operational changes shift the equilibrium toward higher yields of ammonia according to Le Chatelier's Principle?
A.Increasing total pressure and lowering the operating temperature
B.Decreasing total pressure and raising the operating temperature
C.Continuously removing nitrogen and hydrogen gases from the reactor
D.Adding an inert gas at constant volume
Explanation: The forward reaction converts 4 moles of gaseous reactants into 2 moles of gaseous product (Δn_gas = -2). Increasing total pressure shifts equilibrium toward the side with fewer gas molecules (favoring NH₃). Because the reaction is exothermic (ΔH < 0), lowering temperature shifts equilibrium in the forward exothermic direction.
4During operation of a Daniell cell made from zinc and copper half-cells, which description of the electrodes and electron flow is correct?
A.Zinc is oxidized at the anode, and electrons flow through the external circuit from zinc to copper
B.Copper is oxidized at the anode, and electrons flow from copper to zinc
C.Zinc ions are reduced at the zinc electrode, and electrons flow from copper to zinc
D.Both metals are oxidized, so no electrons pass through the external circuit
Explanation: Zinc atoms lose electrons at the anode: Zn → Zn²⁺ + 2e⁻. Those electrons travel through the external circuit to the copper cathode, where Cu²⁺ ions gain electrons and form copper metal.
5During the electrolysis of an aqueous copper sulfate solution (CuSO₄), how many grams of copper metal (molar mass M = 63.5 g/mol) are deposited on the cathode by an electric current of I = 9.65 A flowing for t = 1,000 seconds? (Faraday constant F = 96,500 C/mol e⁻, reaction: Cu²⁺ + 2e⁻ → Cu).
A.3.175 grams
B.6.350 grams
C.1.588 grams
D.12.70 grams
Explanation: Total charge passed is Q = I · t = 9.65 A × 1,000 s = 9,650 Coulombs. Number of moles of electrons is n_e = Q / F = 9,650 / 96,500 = 0.10 mol e⁻. Reduction of Cu²⁺ requires 2 electrons per atom of copper (z = 2). Moles of copper deposited = 0.10 / 2 = 0.050 mol. Mass deposited = moles × molar mass = 0.050 mol × 63.5 g/mol = 3.175 grams.
6A collected dataset contains blank cells, duplicate rows, and impossible values. What should be done before the data are used for analysis or machine learning?
A.Clean the data by handling missing values, duplicates, and outliers according to the purpose of the analysis
B.Drop every row containing a blank while leaving duplicate and impossible values unchanged
C.Replace every blank with zero while retaining duplicate and impossible values
D.Remove duplicate rows but treat blanks and impossible values as valid observations
Explanation: Data cleaning identifies and handles missing values, outliers, and duplicate records before analysis. The appropriate treatment depends on why the data were collected and how they will be used.
7In a neural network that classifies photographs, what is the principal role of the hidden layers?
A.Process input information and extract features used by the output layer
B.Normalize the raw photograph before any learned weights are applied
C.Convert the network's final scores into a class label without extracting features
D.Store the labeled training photographs verbatim for direct lookup
Explanation: The input layer receives data, hidden layers process those data and extract features such as shapes or patterns, and the output layer produces the classification result.
8In acidic solution, orange dichromate ions are converted to green chromium(III) ions during a redox reaction. What has happened to the dichromate ions?
A.They have gained electrons and been reduced
B.They have lost electrons and been oxidized
C.They have evaporated without changing oxidation state
D.They have acted as a reducing agent
Explanation: Dichromate is a strong oxidizing agent in acidic solution. It accepts electrons and is reduced to chromium(III), whose ions give the solution its green color.
9A student asks an AI system to create a new illustration from a written prompt. Which description and caution are both appropriate?
A.This is generative AI using learned patterns to produce new content, and the output should still be checked
B.This is only alphabetical data sorting, so the output cannot contain learned visual patterns
C.This is a fixed-formula calculation, so the same prompt must always yield a verified fact
D.This is generative AI, so every detail in the output is guaranteed to be accurate
Explanation: Creating a new illustration from a prompt is a generative-AI task. The system draws on patterns learned from data, but its output still needs human review because it may contain errors or bias.
10A reaction is slow because few collisions have enough energy to produce a reaction. Why can adding a catalyst make the reaction faster?
A.It provides an alternative reaction pathway with lower activation energy
B.The catalyst increases the activation energy E_a, making the reaction slower
C.The catalyst alters the equilibrium constant K_c of the reaction
D.The catalyst increases collision frequency while leaving the activation-energy barrier unchanged
Explanation: A catalyst offers another reaction pathway with a lower activation-energy barrier. More collisions can therefore lead to reaction, while the catalyst does not change the equilibrium position.

About the Egyptian Baccalaureate Engineering & Computer Science Exam

Law 169 of 2025 and Ministerial Decision 213 of 2025 establish the optional Egyptian Baccalaureate as a three-year secondary qualification beginning in 2025/26. The Engineering and Computer Science pathway counts four Grade 11 papers—Arabic Language, Egyptian History, First Foreign Language, and either Chemistry or Programming and Artificial Intelligence—plus Grade 12 Advanced Mathematics and Advanced Physics, each marked out of 100. Current rules require completion of 60% of weekly and monthly performances and assessments before the first examination opportunity; Grade 11 also includes non-counted Financial Culture and compulsory practical-only Physical Education. The Ministry has not published a qualification-wide assessment-language rule. This English MCQ bank covers only currently published Grade 11 Chemistry and Programming/AI material and is not an official translation, essay simulation, or substitute for school assessment.
