For each of the following unbalanced equations,
calculate how many moles of the second reactant
would be required to react completely with
exactly 25.0 g of the first reactant. Indicate
clearly the mole ratio used for each conversion.
a. Mg(s) + CuCl2(aq) → MgCl2(aq) + Cu(s)
b. AgNO3(aq) + NiCl2(aq) →
AgCl(s) + Ni(NO3)2(aq)
C. NaHSO3(aq) + NaOH(aq) →
Na2SO3(aq) + H2O(l)
d. KHCO3(aq) + HCl(aq) →
KCl(aq) + H2O(l) + CO (g)
