Potassium thiosulfate (K2S2O3) is used to remove any excess chlorine from fibers and fabrics that have been bleached with that gas. The reaction is K2S2O3 + 4Cl2+ 5H2O→2KHSO4 + 8HCl a. What mass of HCl will be produced at the same time that 45.0 g of KHSO4 is produced? (5 pst) b. What mass of Cl2 is consumed along with 2.20 x 1024 molecules of H2O? (5 pts)

catya that's not even a b or c

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.
