Balance the following reactions by filling in the correct coefficients. Even though you usually do not put the number 1 as a coefficient, do so for this quiz
Question 1
1.
6K + S2 → 2K3S
What is the mole ratio of K to S2?
Question 2
2.
6Na + P2 → 2Na3P
How many moles of Na do I need to produce 0.8 mol of Na3P, assuming I have plenty of P2?
Question 3
3.
3H2CrO4 + 2Fe(OH)3 → Fe2(CrO4)3+ 6H2O
How many moles of Fe(OH)3 is required to react 3.9 mol of H2CrO4?
Question 4
4.
2Rb + 2H2O → 2RbOH + H2
How many moles of RbOH will be produced with 4.5 mol of Rb is reacted with plenty of H2O?
