Answer: Option (D) is the correct answer.

Explanation:

An organic compound is a compound which contains a carbon and hydrogen atom.

For example, $CH_{4}$ is a methane because the suffix "ane" determines alkane as the functional group present in it.

Therefore, an organic compound also include a functional group because of which without any test we can identify that it is an organic compound.

Some functional groups are -OH, COOH, C=O, - $NH_{2}$ etc.

Thus, we can conclude that the properties of organic compounds are determined by their functional group.

Consider the reaction between hydrazine and hydrogen to produce ammonia, N2H4(g)+H2(g)→2NH3(g). Use enthalpies of formation and

sammy [17]

Answer:

The answer is explained below:

Explanation:

Given the chemical equation:

N2H4(g)+H2(g)→2NH3(g)

The standard enthalpy of formation is given by the following formula:

ΔH^0 rxn = ∑ B reactants - ∑ product

-187.78 kJ/mol = [( 1x B N-N) + (1 x B N-H ) + (1 x b H-H)] - [ 6 x B N-H]

-187.78 kJ/mol = [( 1x B N-N) +(4 x 391 kJ/mol) + (1 x 436 kJ/mol)] - [ 6x 391 kJ/mol ]

-187.78 kJ/mol = B N-N + (1564 + 436 - 2346) kJ/mol

B = 158.22 kJ/mol

So, in this case the enthalpy of N-N bond is 158 kJ/mol

What is the mass of H2O produced when 14.0 grams of H2 reacts completely with 2.0 grams of O2?

Vladimir79 [104]

Balanced chemical equation:

2 H2 + 1 O2 = 2 H2O

4 g H2 -------> 32 g O2 -----------> 36 g H2O
↓ ↓ ↓
14.0 g ---------> 2.0 g O2 ----------> mass H2O ?

32 * mass H2O = 2.0 * 36

32 * mass H2O = 72

mass of H2O = 72 / 32

mass of H2O = 2.25 g

hope this helps!.
