5.Samples of baking soda and vinegar at room temperature are mixed together. The resulting solution has a lower temperature than the original temperature of the vinegar. Which statement correctly describes how the system could be modified so that thermal energy is absorbed faster? A. Decrease the amount of baking soda used.
B. Increase the concentrations of the chemicals used.
C. Increase the size of the container used.
D. Decrease the temperature of the environment so more energy flows away from the solution.

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.

the objects have the same charge is correct.
