The correct answer is 2Ca(s)+O_2(g)→ 2CaO(s).

Combustion of calcium in air calcium is Ca with O_2 (air)

Thus the equation is:

2Ca(s)+O_2(g)→ 2CaO(s)

Calcium and oxygen react at room temperature to generate a thin layer of CaO that shields the metal from further oxidation. When burned, calcium may ignite and react with both oxygen and nitrogen to produce calcium oxide (CaO) and calcium nitride (Ca3N2).

What is combination reaction ?

A chemical reaction known as a "combination reaction" occurs when two or more reactants combine to create a single product. Such a kind of reaction does not produce any byproducts. These processes are typically exothermic, which means heat is produced.

Answer: AIBN is good radical initiator

Explanation:

A radical in organic chemistry refers to any specie having a single unshared electron. An initiator is any specie capable of producing radicals thus starting up a chain reaction. Azobisisobutyronitrile is a good initiator basically owing to its structure. It forms radicals by breaking up to release nitrogen gas as shown in the image attached. The two radicals formed both contain the -CN group which stabilizes the radical.

Explanation:

If you remeber a balloon in hot air, it pops. This is because the molecules are moving too fast and need more space to move, thus popping the balloon. If you put a balloon in cold air, then it shrinks, the molecules not moving fast enough and don't need as much space.
