In the following chemical reaction, how many moles of N2 are needed to completely react with 3 moles of H2? N2 + 3 H2 2 NH3

2 answers:

6 0

N2 + 3H2 produces 2NH3 If that is the correct chemical equation. Reactants N = 2 H =6 Products N =2 H= 6 The answer is just one.

Answer: a) 1

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$N_2+3H_2\rightarrow 2NH_3$

According to stoichiometry :

3 moles of hydrogen reacts with 1 mole of nitrogen to give 2 moles of ammonia.

Thus 1 mole of hydrogen are needed to completely react with 3 moles of nitrogen.

Answer:

54 g is the theoretical yield

Explanation:

This is the reaction:

2H₂ + O₂ → 2H₂O

So 2 moles of hydrogen react with 1 mol of oxygen, to produce 2 mol of water.

If I have 3 moles of H₂ and 2 moles of O₂, the my limiting reactant is the hydrogen.

1 mol of O₂ react with 2 moles of H₂

S 2 mol of O₂ would react with 4 moles (I only have 3 moles)

Then, ratio is 2:2 the same as 1:1

As 2 mol of H₂ produce 2 moles of water, 3 moles of H₂ will produce 3 moles of H₂O.

This is the theoretical yield in moles. Let's convert them to mass (mol . molar mass)

3 mol . 18g/m = 54 g

A or B i need help fast

Answer: I would go with B

Explanation: The motor in a circuit isn't moving. That's very vague, but it doesn't show any evidence that an electrical current is going through it, likewise it doesn't show that an electrical current ISN'T going through it. However in regards to this question I would go with B.
