I think it is feeling warm air while standing in front of the blower from a heating system.
Hope this helps! :)
Answer:
just trust me the answer is B
(l ) the mass ratios of the substances in the reaction
<u>(2) the mole ratios of the substances in the reaction</u>
(3) the total number of electrons in the reaction
<span>(4) the total number of elements in the reaction</span>
To answer this, we use Raoult's Law where the partial pressure is equal to the product of the fraction of the gas in the mixture and its total pressure. Also, we use Dalton's Law of Partial Pressure where the total pressure is equal to the sum of the partial pressure of the gases in the mixture.
Ptotal = 73.44 + 128.52 + 2.04 = 204 atm
201.96 = x (204)
x = 0.99

Explanation:
Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.
Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.
This reaction, just by definition is endothermic.
