The phase of a sample of a molecular substance at STP is not determined by its
MAVERICK [17]
Phase is not determined by the number of molecules, as a substance with any number of molecules can be either solid, liquid, or gas.
Arrangement of molecules and molecular structure matter, since solids are closely packed together, gases are not, and liquids are in between. Intermolecular forces are also stronger for solids and liquids than they are for gases.

Choose all of the following mole ratios that are correct for the reaction given below. Be sure to choose all that apply.
Dennis_Churaev [7]

Answer:

2 moles NH3 = 1 mole of N2

3 moles of H2 = 1 mole of N2

3 moles of H2 = 2 moles of NH3

Explanation:

The balanced equation for the reaction is given below:

N2 + 3H2 —> 2NH3

From the balanced equation above,

1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3.

Thus, we can say that:

1 mole of N2 = 3 moles of H2

1 mole of N2 = 2 moles of NH3

3 moles of H2 = 2 moles of NH3

Thus, considering the options given above, the right answers to the question are:

2 moles NH3 = 1 mole of N2

3 moles of H2 = 1 mole of N2

3 moles of H2 = 2 moles of NH3
