A researcher needs to combine 500 mL of two reactants for an investigation. However, the reaction is strongly exothermic and tends to damage equipment when the reactants are simply mixed together. To keep the reaction from damaging equipment, what is the BEST way to modify the reaction process?

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
