...and grams......4 problems...? 1. given the following equation: KCIO3------>KCl + O2
how many molecules of O2 can be produced by letting 1.2x10^23 moles of KClO3 react?
2. given the following equation: K+Cl2----->KCl
how manty molecules of KCl is produced from 2.50gX10^23 molecules of K and excess Cl2. from 1.00g of Cl2 and excess k?
3. given the following equation: Na2O+H2O----->NaOH
how many molecules of NaOH is produced from 1.2x10^23 molecules of Na2O? how many molecules of Na2O are required to produce 1.60x10^23 molecules of NaOH?
given the following equation Fe+S8---->FeS
4. what number of atoms of iron are needed to react with 16.0x10^23 atoms of sulfur? how many molecules of Fes are produced?
show all work and you will get 10 pts............try to do all of them.......
