Question

A 1.000 g sample of nitrogen combined with a 0.0720 g sample of hydrogen to form N2H2. What compound is formed if 1.000 g of nitrogen combines with 0.2160 g of hydrogen?
N2H6 NH3 NH4+ N4H4

Answer 1

Answer:

N₂H₆

Explanation:

A 1.000 g sample of nitrogen combined with a 0.0720 g sample of hydrogen to form N₂H₂ .

1.000 g of nitrogen combines with 0.2160 g of hydrogen in the next compound .

In this compound the component of nitrogen remains the same but the component of hydrogen becomes .2160 / .0720 = 3 times .

Hence component of hydrogen in the new compound will change from

H2 to H6 .

Hence the chemical formula of new compound will be

N₂H₆ .
