The complete equation representing the synthesis reaction for the formation of ammonia is: 3 H₂ + N₂ ⇒ 2 NH₃
<h3>What is a synthesis reaction?</h3>
It is a reaction in which 2 or more substances combine to form 1 product.
Let's consider the following incomplete synthesis reaction.
3 H₂ + ____ ⇒ 2 NH₃
According to Lavoisier's law, the mass and the elements must be conserved in a chemical reaction. So, since there is nitrogen to the right, the missing element to the left must be nitrogen. Molecular nitrogen is diatomic.
The complete reaction is:
3 H₂ + N₂ ⇒ 2 NH₃

Answer:
0.3 moles of H2 will be produced.
Explanation:
Balanced reaction: 2 Al + 6 HCl → 2 AlCl3 + 3 H2
Given Al mass = 5.4 g, we know Mr of Al is 27
Using the formula:
moles = mass / Mr
moles of Al = 5.4 / 27
moles of Al = 0.2 moles
Here we see that "2" molar mass before Al; so in this reaction, "1" molar mass will have [(0.2)/2] = 0.1 moles. He see "3" molar mass before H2, therefore moles of H2 is (3 * 0.1) = 0.3 moles.
Hmm, I am not quite sure but if I am probably your best bet so I'd go with, either B or D.
