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

The answer is NH3.

Explanation:

The N2H2 (O hydrazine) is formed when from the synthesis of ammonia and hydrogen peroxide.

Or also formed when a 1,000g sample of nitrogen is combined with a 7.2 x10∧-2 sample of hydrogen.

0.2160 of hydrogen is 3 times 7.2 x10∧-2.

It means that the compound would look like:

N2H6.

But in chemistry, if there are divisible numbers in a compound, they must be divided:

NH3.
