Answer:
A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A–A) and heterodimer when they are not (e.g. A–B).
Explanation:
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?"

<span>Scientists believe that tectonic activity is not occurring on the moon. This is <span>because the moon lacks radioactive decay. The moon is not constantly supplied heat and energy from decaying unstable isotopes like Earth. Also, Earth is heated by the original heat during its formation. Since the moon was most likely broken off from earth, it lacks this central heat. @Kb0812 Hope this helps and if your feeling generous feel free to leave a rate, thanks and brainliest because it would really help me reach expert and I would appreciate it ;)</span></span>
<span>Nudation is the process wherein an ecological system experiences new growth after a major event. Given that a drought killed all of the plants in the farmland and the wind and birds moved new plants into the now barren area, this is an ecological succession.</span>
Answer:
Emulsifier
Explanation:
Emulsifier are the chemical additives which are required to breaking up fats or lipids globules into much smaller emulsion droplets.
An emulsifier consist of one oil-friendly and one water-friendly end. When an emulsifier added with fat or lipid, the emulsifier face towards the oil/water or air/water interface reduces the surface tension to make emulsion more stable.
Emulsification of fat makes the food easy to absorbed by small intestine.
Hence, the correct answer is "Emulsifier ".
