4. When NH4NO3 is dissolved in water, the temperature of the water decreases. When NaOH is dissolved in a
separate water sample, the temperature of the water
increases. Based on these observations, it can be
concluded that the dissolving of
A) both salts is endothermic
B) both salts is exothermic
C) NH4NO3 is endothermic and the dissolving of
NaOH is exothermic
D) NH4NO3 is exothermic and the dissolving of
NaOH is endothermic

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.
