Is the official RBSE Praveshika Science exam multiple-choice only?

No. Official RBSE papers mix objective and constructed-response tasks. The 100 questions here are an English-language MCQ study adaptation for concept practice only.

What are full marks and duration for RBSE Science?

RBSE Class 10 / Praveshika subject schemes in the official syllabus commonly use Theory 80 + Sessional 20 = 100 marks with a 3 hour 15 minute theory paper. Confirm the exact scheme for code 7 in the current RBSE syllabus PDF on rajeduboard.rajasthan.gov.in.

What is the passing score?

Minimum 33% marks in the subject as per RBSE Secondary/Praveshika examination regulations (confirm current session circulars).

How much does the exam cost?

As per RBSE annual examination fee notification for school/private candidates (commonly published figures for the 2026 Secondary/Praveshika cycle have been about INR 600 regular / INR 650 private for the full board form — confirm the current circular on rajeduboard.rajasthan.gov.in; subject papers are not separately priced on this page).

Where are official statistics and syllabus?

Subject-wise 2026 result statistics and board materials are published by RBSE at https://rajeduboard.rajasthan.gov.in/statistics2026.htm and syllabus PDFs under anudeshika / books sections of https://rajeduboard.rajasthan.gov.in. Prefer primary board PDFs over third-party summaries.

Is this bank an official RBSE translation?

No. OpenExamPrep publishes one English-language practice bank per exam ID. Target-language terms and texts may appear when they are integral to the skill, but stems, explanations, and SEO copy are English study adaptations — not official translations or language-environment simulations.

How should I use MCQs for a mixed written/practical paper?

Use MCQs for daily concept drills and self-check. Also practise full written answers from RBSE model papers under timed conditions.

1Which observation best indicates that a chemical reaction has taken place when zinc is added to dilute sulphuric acid?

A.The zinc pieces simply change shape without gas.

B.Bubbles of a colourless gas form and the metal slowly disappears.

C.The solution freezes solid at room temperature.

D.Zinc becomes magnetic immediately.

Explanation: Zinc reacts with dilute H₂SO₄ to form zinc sulphate and hydrogen; effervescence and consumption of metal show a chemical change.

2The balanced equation for complete combustion of methane is CH₄ + 2O₂ → CO₂ + 2H₂O. How many moles of oxygen are needed for 3 moles of methane?

A.1.5 mol

B.3 mol

C.6 mol

D.2 mol

Explanation: The coefficient ratio CH₄ : O₂ is 1 : 2, so 3 mol CH₄ require 6 mol O₂.

3When silver chloride is exposed to sunlight, it turns grey. This reaction is an example of:

A.Combination reaction only

B.Photolytic decomposition

C.Double displacement without light

D.Neutralisation

Explanation: 2AgCl → 2Ag + Cl₂ in sunlight is decomposition driven by light (photolysis).

4In the reaction Fe₂O₃ + 2Al → Al₂O₃ + 2Fe, aluminium acts as:

A.An oxidising agent only

B.A reducing agent

C.A catalyst that is unchanged

D.A spectator ion

Explanation: Al removes oxygen from Fe₂O₃ (gains oxygen itself), so Al is oxidised and acts as the reducing agent (thermite-type redox).

5If 4 g of hydrogen completely reacts with 32 g of oxygen to form water, the mass of water formed is:

A.28 g

B.36 g

C.16 g

D.4 g

Explanation: By conservation of mass, 4 g H₂ + 32 g O₂ = 36 g H₂O when reaction is complete and no other products form.

6Which pair correctly matches a reaction type with an example?

A.Combination: CaCO₃ → CaO + CO₂

B.Displacement: Zn + CuSO₄ → ZnSO₄ + Cu

C.Decomposition: N₂ + 3H₂ → 2NH₃

D.Double displacement: 2Mg + O₂ → 2MgO

Explanation: Zn displaces Cu from CuSO₄; that is a classic single-displacement reaction.

7Which indicator turns pink in basic solution and remains colourless in acid?

A.Methyl orange

B.Phenolphthalein

C.Blue litmus

D.Turmeric paper in acid

Explanation: Phenolphthalein is colourless in acidic/neutral media and pink/magenta in basic solution.

8The pH of pure water at 25 °C is approximately:

A.0

B.7

C.14

D.1

Explanation: Pure water is neutral with [H⁺] = 10⁻⁷ mol L⁻¹, so pH = 7 at 25 °C.

9Baking soda used in cooking is chemically:

A.Na₂CO₃

B.NaHCO₃

C.NaOH

D.CaOCl₂

Explanation: Baking soda is sodium hydrogen carbonate, NaHCO₃.

10When dilute HCl is added to a blue solution of copper(II) carbonate suspension, a gas turns lime water milky. The gas is:

A.H₂

B.O₂

C.CO₂

D.Cl₂

Explanation: Carbonates react with acids to liberate CO₂, which turns lime water milky by forming CaCO₃.
