How do i find the q of a rxn if the density of water is 1.0g/ml and the cs is 4.18 j/g*c?
i have 50ml of 1m hcl and 50ml of 1m naoh, and the change in temperature was 6.4c.
i got -2675.2j, but i have no idea if that seems reasonable. the equation is: q of rxn = (-m of soln)(cs)(change in temp of soln).

the answer would be a

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.
