A reaction has a rate of 0.026g/s. This was established from measuring the mass lost from a sample of calcium carbonate across three and a half days. If the sample of calcium carbonate had a mass of
581kg at the beginning of the reaction, what was its mass at the end?
ANSWER PLZZZ ​

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
