Various properties of a liquid are recorded during an experiment. the volume of the liquid is measured to be 25.5 milliliters. the density of the liquid is found to be 1.76 g/ml. the liquid is blue in color. which item(s), if any, of the information recorded is/are qualitative data?

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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.
