A gas is produced when 25 g of substance X is mixed into 60 g of solution Z in a beaker. The mass of the solution in the beaker after the reaction is 75 g. What is the mass of the gas released? (X + Z -> gas + solution)

mass of the gas = 10 g

The law of conservation of mass :

In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

Reaction

mass before reaction=mass after 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.
