D surface tension because, adhesion is sticking, b makes no sense for this question, and heat has nothing to do with it either, because it distributes it's weight throughout its legs so it doesn't sink (it doesn't weigh much so this works.)

Hope this helps don't forget to hit that heart :)

We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, nh3
pentagon [3]

To form ammonia, we can react 2 molecules of N₂ with 6 molecules of H₂. Once the reaction has completed, the total molecules of each gas will be: 1 molecule of nitrogen, 3 molecules of hydrogen, and 4 molecules of ammonia.

<h3>How to predict the total molecules of reactants and products?</h3>

The formation reaction of ammonia needs one molecule of nitrogen and 3 molecules of hydrogen. The reaction is as shown in the equation below:

N2(g) + 3H2(g) --> 2NH3(g)

2N2(g) + 6H2(g) --> 4NH3(g)

They will form a new product as four molecules of NH₃. Speaking in the present time after the reaction has completed, half of the reactants (N₂ and 3H₂) are gone to form the ammonia. Hence, the correct answer is: 1 N₂, 3 H₂, and 4 NH₃.


This question seems incomplete. The complete query is as follows:

"We are reacting two molecules of nitrogen gas with six molecules of hydrogen gas to form ammonia, NH₃. How many molecules of each type of gas will be present once the reaction has completed?"
