For each of the following unbalanced equations, indicate how many moles of the second reactant would be required to react exactly with 0.275 mol of the first reactant. Show all work below.
a.) Cl2(g) + KI(aq) ---> I2(s) + KCl(aq)
b.) Co(s) + P4(s) ---> Co3P2(s)
c.) Zn(s) + HNO3(aq) ---> Zn(NO3)2(aq) + H2(g)
d.) C5H12(l) + O2(g) ---> CO2(g) + H2O(l)
