Chemicals in polluted air combine with water vapor to form acid rain is True
Answer:
A. No, because we are not given specific values for w and q.
Explanation:
The change of internal energy of a system is:
ΔE = q + w
where q represents heat and w represents work.
It is necessary to know the magnitude and the sign of q and w in order to know if the system's internal energy is increasing or decreasing.
<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water.
If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up.
That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>
