Answer:
CaCO3 + 2HCl —> CaCl2 + CO2 + H2O
Explanation:
Moles Cu+2 = M * V
= 0.05 L * 0.011 m
= 0.00055 moles
when the molar ratio of Cu2+: EDTA = 1:1 so moles od EDTa also =0.00055 moles
and when the Molarity of EDTa = 0.0630 M
∴ Volume of EDTA = moles / Molarity
= 0.00055 / 0.0630
= 0.0087 L = 8.7 L
No because 2 pounds only equals 16 ounces times 2 so it equals 32 ounces which is not bigger than 80
