Answer:

1. charophytes

Explanation:

  • These are macrophytes that grow entire in the freshwater and become fossilized by the calcification oozes,  going back to the Paleozoic era about 250 million years ago.
  • And they are unicellular to multi-cellular organisms also found in moist terrestrial habitats.

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?"
