Question

I only need help with the highlighted ones please :)

1. Zinc metal reacts with aqueous hydrochloric acid to produce zinc(II) chloride and hydrogen gas.
a. Write a balanced chemical equation including phase tags for this reaction.
b. What volume of 0.118 M HCI is required to completely react with 0.103 g of solid zinc?
c. When 0.103 g of solid zinc is combined with enough hydrochloric acid to make 50.0 mL of solution in a
coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.5 °C to
23.7°C. Determine qrn using 1.0 g/ml for the density of the solution and 4.184 J/g°C as the specific heat
of the solution.
d. Determine AHn when 1.00 mole of zinc reacts and add this information to your balanced chemical
equation to make it a thermochemical equation.
Use your thermochemical equation to determine AH.m for the following reactions:
е.
i.
2 moles of Zn are reacted with excess hydrochloric acid
ii.
5.67 g of Zn is reacted with excess hydrochloric acid
iii.
The reverse reaction occurs.
