N2 + 3H2 → 2NH3

How many grams of hydrogen, H2, are necessary to react completely with 50.0 g of nitrogen, N2?

5.4 g

28.0 g

2.0 g

10.7 g

10.7 g of H₂. Last option

Explanation:

The reaction shows that 1 mol of N₂ reacts with 3 moles of hydrogen to produce ammonia.

Let's make a rule of three with the reactant, to find the relation.

We need to convert the mass of N₂ to moles

50 g / 28g/mol = 1.78 moles

The equation is: N₂ + 3H₂ → 2NH₃

Ratio is 1:3

1 mol of N₂ reacts with 3 moles of hydrogen to produce ammonia

Therefore 1.78 moles will react with (1.78 . 3 ) / 1 = 5.36 moles

We convert the moles to mass to find out the answer

5.36 mol . 2g / 1 mol = 10.7 g

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
