PLEASE HELP
Each equation is balanced. Show your work as you solve the problems below.
1. 2 KClO3=2 KCl + 3 O2
a. If you have 4.3 mol KCl, how many moles of KClO3 will you need to start with?
b. If you start with 2.3 mol KClO3, how many moles of O2 will be produced?
2. Br2 + 2 NaI =2 NaBr + I2
a. Have: 3.1 moles of NaBr, how much NaI do you need?
b. Have .074 moles of Br2, how much I2 is produced?
3. 4 Fe + 3 O2= 2 Fe2O3
a. If 2.01 moles of Fe2O3 are produced, how much Fe do you need to start with?
b. Have: .005 moles O2, how much Fe is needed?
4. 2 Na3PO4 + 3CaCl2 = Ca3(PO4)2 + 6 NaCl
a. If you have .09 moles of Ca3(PO4)2, how much CaCl2 do you need to start with?
b. Have 1.76 mole of Na3PO4, how much NaCl is produced?
5. SO3 + H2O =H2SO4
