Objective: In the Virtual Lab, you will balance chemical equations and formula weights. The formula
weight of a substance is found by adding the atomic masses of each atom present.
Chemical Formula #1 2Mg+1O₂=2MgO
Chemical Formula # 2 Fe(C2H3O2) 2
Chemical Formula #3 Ag C2H3O2
1. How did you balance the chemical equations?
By entering numbers in the blank.
2. How did you figure out the coefficients?
Before solving a limiting reagent problem, you MUST first do a than Mg(OH)2, so it may
seem that it is in excess but always reason out your out all the problems did for the
second example, but after you find the moles of both reactants, you're supposed to
divide the number of moles by the coefficient.
