Assertion- Reasoning type questions
9. Assertion : When ferrous sulphate crystals are heated strongly, its colour
changes from green to brown.
Reason : It undergoes displacement reaction.
10. Assertion : Respiration is an endothermic reaction.
Reason: Endothermic process absorbs energy.
11. Assertion: Brown fumes are produced when lead nitrate is heated.
Reason: Oxygen gas is produced due to the decomposition of lead nitrate.
12. Assertion: Calcium carbonate when heated gives calcium oxide and water.
Reason: On heating calcium carbonate, decomposition reaction takes
place.
13. Assertion: In a reaction of magnesium with oxygen, magnesium serves as a
reducing agent
Reason: The substance which gains oxygen in a chemical reaction is a
reducing agent.
Assertion: Rusting of iron is a chemical change.
Reason: The chemical properties of hydrated Fe2O3 are different from
iron and oxygen

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
