The number of atoms of each element on reactant and product side must be equal. a) KOH(aq)+ZnCl2(aq)-> KCl2+ZnOH The second half of the equation is how i had done on the exam but he said its not balanced. If the equationwas not balanced correctly, write the correctly balanced equation. Balancing Strategies: This is a more challenging reaction, mostly because you have a number oxygen is on the product side of the equation.And their spread out in the MgO, NO2, and O2. Following are some equation input format examples: 1. #2Mg(s)+O_2(g)->2MgO(s)# Now, there are equal amounts of magnesium atoms and oxygen atoms on both sides, and so the equation is balanced. This equation means that 1 mole of Mg can completely react with 1/2 mole of O2. That also suggests that 2 moles of Mg can react with 1 mole of O2. Mass is conserved rather than created or destroyed so when a chemical equation is written, it must be balanced so that there is the same amount of reactants going in as yielded product. 2 Mg + 1 O2 -----> 2 MgO. hope i helped.
