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

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

the temperature of the gas, in k, not celsius.
