Find the normality of a solution containing 20g of h2so4(sulfuric acid) per 500ml of solution. the molar mass of h2so4 is 98 g/eq. h2so4 has two replaceable h+.

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.
