Josephine reacts $10\mathrm{.}0$ mL of $0\mathrm{.}50$ M HCl with $10\mathrm{.}0$ mL of $0\mathrm{.}50$ M KOH. The solution experienced a

temperature rise of six degrees Celcius. If she doubles the volume of acid and base she used $($while not

changing the concentrations$),$ would the temperature rise be half of the original $$T $(3$ C$),$ the same as

the original $$T $(6$ C$)$ or twice that of the original $$T $(12$ C$)?$ Justify your answer.

$5.$ List two things that are necessary for an

effective collision at the molecular level.

$6.$ List one way a student can increase the rate

that his rock salt $($magnesium sulfate pieces$)$

reacts with acid.
