What went wrong – balancing chemical equations
your friend and classmate made a mistake when balancing the following chemical equation.
original unbalanced equation:
fe + h20 -> fe3o4 + h2
your classmate’s incorrectly balanced equation:
fe3 + 4h2o -> fe3o + 4h2
analyze where your friend went wrong when trying to balance the equation. then, instruct him or her on how to balance the equation correctly. also, show the final balanced equation by inserting an equation at the end of your response.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7

cu2o
