Some chemical reactions take a very long time to go to completion or cannot be directly measured. Which law allows one to use two or more thermochemical equations to
calculate the heat of a reaction indirectly?
-Pascal's Principle
-Hess's law of heat production
-Hess's law of heat division
-Hess's law of heat summation

D

Explanation:

If you add two or more thermochemical equations to give a final equation, then you also add the heats of reaction to give the final heat of reaction

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.
