Because chemical reactions take place in molar ratios. The number of moles of each kind of atom has to be the same on both sides of the equation.

Why do you need a balanced chemical equation to do sticiometric problems?
Do you mean stoichiometry? The equations need to be balanced so they are stable. They just need to be balanced...
How many milliliters of 0.248M HCl are needed to react with 1.36 grams of zinc to produce hydrogen?
First, write a balanced equation for this reaction. The reactants are HCl and Zn and the products are ZnCl2(aq), and H2(g). For how to write a balanced equation, see the Related Questions to the left. Then, convert the grams of Zn into moles of Zn. To do that, see the Related Questions to the left. Then use stoichiometry to determine how many moles of HCl are necessary to react with that number of moles of Zn. See the Related Questions to the left for how to solve stoichiometry problems. Finally, determine how many milliliters of solution you need to get that many moles of HCl. To do that, use this equation: number of moles = number of liters * molarity
How do chemists use balanced equations?
To correctly determine the balanced chemical equation, one must make sure that the products are appropriately relating to the reactants and make sure that the equation is balanced with the lowest coefficients. That should help.
Each of the four types of reaction stoichiometry problems requires using a?

Do stoichiometry problems involve predicting how fast a reaction will occur?
No. Stoichiometry studies the quantities involved in chemical reactions. How fast a reaction occurs is a branch of chemistry called kinetics.

Why is it essential to use balance equations in solving stoichiometric problems?
It is essential to use balanced equations when solving stoichiometric problems because each kind of atom has to be the same on both sides of the equation. The chemical reactions that take place are molar ratios.
Mass mass problems?
Mass-mass problems can be solved in various ways. You should start by writing a balanced equation for chemical reaction involved and eventually change the mass into moles which will facilitate the comparison and allow you to calculate the number of moles required.
What is mol ratio used for?
