The percent yield is given by the actual and the theoretical yield. The percent yield of the 2.73 gm compound is 80.3%. Thus, option b is correct.
<h3>What is the percent yield?</h3>
The percent yield is the ratio of the actual yield to the theoretical yield. It is calculated as:
% Yield = Actual yield ÷ Theoretical yield × 100%
= 2.73 ÷ 3.84 × 100%
= 71.09 %
As the closest number to 71.09 is 80.3% the percent yield will be 80.3%.
There is no limiting reagent in the reaction between the copper iodide and mercury iodide as the moles of the reactants and the products are in equal quantity.
Hence, option b. there is no limiting reagent in this reaction.

An object will not move if:
A.) All forces acting on it are balanced.
This can be proved by example, while similtaneously proving the other answers wrong.
Take for example;
Two people are pushing on a box with 30N, one person being on the right, the other being on the left.
The opposing forces are exerting against eachother, creating a stable position on the box.
How about "if there was no gravity on it"?
Take for example an airplane. Turbulence effects the plane even when it's defying gravity.
The next two are easy to debunk.
"It's mass increases"
This can be disproved by anything.
If I were to become bigger, I'm not moving, my body is just extending in size.
This also applies to weight.
The answer is A.)
I hope this helps!
Answer:
I'm pretty sure the correct answer is b, I took this quite a while ago so I might not be right I would do some research about it. hope I helped!
Ammonium iodide, or NH₄I, is a salt. Since all salts are strong electrolytes, when ammonium iodide is dissolved in water, it would dissociate into ammonium ions and iodide ions. Hence, the major species present would be: <em>NH₄⁺ and I⁻ ions</em>.
