Sample AP SSC General Science (BSEAP) Practice Questions

Try these sample questions to test your AP SSC General Science (BSEAP) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following is an example of a combination reaction?
A.CaCO3 → CaO + CO2
B.2H2 + O2 → 2H2O
C.Zn + CuSO4 → ZnSO4 + Cu
D.2AgCl → 2Ag + Cl2
Explanation: In a combination reaction two or more substances combine to form a single product. Hydrogen and oxygen combine to form water.
2A chemical equation is balanced so that it obeys which law?
A.Law of constant proportions only
B.Law of conservation of mass
C.Gay-Lussac's law only
D.Charles's law
Explanation: Balancing ensures the same number of each type of atom on both sides, reflecting the law of conservation of mass.
3Which reaction is an example of a double displacement (precipitation) reaction?
A.2Mg + O2 → 2MgO
B.Na2SO4 + BaCl2 → BaSO4 + 2NaCl
C.2H2O → 2H2 + O2
D.CuO + H2 → Cu + H2O
Explanation: Sodium sulfate and barium chloride exchange ions; insoluble BaSO4 precipitates, a classic double displacement reaction.
4Rusting of iron is best classified as which type of reaction?
A.Displacement only
B.Decomposition only
C.Oxidation (corrosion involving oxygen and moisture)
D.Neutralization
Explanation: Rusting is corrosion of iron in the presence of oxygen and moisture; iron is oxidized to hydrated iron(III) oxide.
5In the reaction Zn + CuSO4 → ZnSO4 + Cu, zinc acts as a:
A.Reducing agent
B.Oxidizing agent
C.Catalyst
D.Precipitating agent
Explanation: Zinc loses electrons (is oxidized) and reduces Cu2+ to Cu, so zinc is the reducing agent.
6Which observation best indicates that a chemical reaction has occurred when lead nitrate is heated?
A.Only a physical change of state with no new substances
B.Evolution of brown NO2 gas and formation of yellow PbO residue
C.Melting without any gas evolution
D.Absorption of oxygen from air only
Explanation: Thermal decomposition of lead(II) nitrate produces lead(II) oxide (yellow when hot/cool appearance noted in class contexts), nitrogen dioxide (brown gas), and oxygen.
7The reaction 2AgBr → 2Ag + Br2 in sunlight is an example of:
A.Electrolytic decomposition
B.Photochemical decomposition
C.Thermal combination
D.Neutralization
Explanation: Silver bromide decomposes under light (used in black-and-white photography), so it is photochemical decomposition.
8Which ion is responsible for the acidic nature of an aqueous solution of HCl?
A.Cl−
B.H+ (or H3O+)
C.OH−
D.Na+
Explanation: Acids produce H+ (hydronium) ions in water; these ions give the acidic properties of HCl(aq).
9A solution with pH 2 compared with a solution of pH 5 is:
A.Less acidic
B.More acidic by a factor of 1000 in [H+]
C.Exactly three times more acidic
D.Basic
Explanation: pH is logarithmic: each unit is a tenfold change in [H+]. From pH 5 to pH 2 is 3 units, so [H+] is 10^3 = 1000 times greater.
10Which indicator turns red in acidic solution and blue in basic solution?
A.Phenolphthalein
B.Methyl orange
C.Litmus
D.Universal indicator only
Explanation: Litmus is red in acid and blue in base—the classic qualitative acid–base indicator taught at Class 10.
