The mass of the entire reaction will technically be unchanged if it is a "closed system". Closed systems are able to exchange energy (heat and work) but not matter with their environment. So the reaction of Alka-Seltzer in water, will produce gas but as long as the system is closed, then the gas produced remains in the ...
The solution answers the question posed and shows how the answer was derived. In addition, the answer provides the chemical reaction that takes place when alka seltzer is introduced to water
