A student doing this experiment accidently spilled some of the previously measured copper chloride solution on his hands. he didn't bother to measure the new volume of the solution. briefly explain how this spill would affect the student's determination of the empirical formula of this sample.

explanation:

0.07 g/cm³

1.37 g/cm³

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.
