Calculate the following quantity: volume of 1.58 M calcium chloride that must be diluted with water to prepare 994 mL of a 6.20 x 10^-2 M chloride ion solution.

the answer is true.

the answer is learned

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
