1.  The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible. Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bond formation).

2. Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.

hope this helps

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?"
