Answer: 109.2g
Explanation:
1 mole N2O = 34 g
46.4g = 46.4/34 moles = 1.365 moles
1 mole N2O is from 1 mole NH4NO3
1.365 moles NH4NO3 = 1.365*80g = 109.2g
Reactions like this one absorb energy because the reactants have less potential energy than the products.
<h3>What is an Endothermic reaction?</h3>
This is the type of reaction in which the reactants absorb heat energy from the surroundings to form products.
This brings about a decrease in the temperature as a result of the reactants having less potential energy than the products thereby making option B the most appropriate choice.

The radiator is next to the triangle, receiving the sound waves and they travel through the radiator up to the other room. She can't hear the sound if the triangle isn't struck near the radiator because the sound waves aren't going through the radiator, and are not able to reach her through the wall. Hope this helps!
