There are 115 known elements as of today (Feb. 13, 2016)
so, 'C' is the correct answer
Answer:
Explanation:1. NaNH2 (1-Butene)
CH3CH2CH2CH2Cl --------------> CH3CH2CH=CH2 + HCl (elimination reaction)
2. Br2, CCl4
CH3CH2CH=CH2 ---------------> CH3CH2CH(Br)CH2Br (Simple addition Reaction)
3. NaNH2 (1-Butyne)
CH3CH2CH(Br)CH2Br ----------------> CH3CH2C≡CH + 2HBr
Sodamide (NaNH2) is a very strong base and generally results in Terminal Alkynes when treated with Vicinal Dihalides.
Alcoholic KOH on the other hand results in the formation of Alkynes with triple bonds in the middle of the molecule.
nickel oxide is the chemical compound with a formula called NiO.

chemical reactions in the kitchen
Baking soda and vinegar create carbon dioxide. In both of these cases, a chemical reaction between a solid and liquid creates a new substance, a gas. Both yeast and baking soda can be used to create a gas.
chemical reactions in living things
when you hard boil an egg, the hydrogen sulfide produced by heating the egg white can react with iron from the egg yolk to form a grayish-green ring around the yolk.
In 0.1 M KOH, thymol blue indicator would appear blue.
