## Report Abuse   Given Reactant and Reagent Give Product. AP Chemistry Polyatomic Ions. Given Reactant and Product Give Reagent. For more information call us at: Balancing Chemical Equations 2 A short tutorial about how to balance chemical equation. Classic Chembalancer This is a nice little Jave Applet that makes balancing chemical equations into a game that gets progressively more difficult as it goes along.

Moles and stoichiometry practice problems Work sheet problems with stoichiometry problems that include mole to mole calculations, mole to gram, percent composition, emperical formulas and balancing equations, limiting reagents.

Now proceed to balance this equation. Make a note of elements on the reactants side and products side. Count the number of elements on each side. Products [2 Hydrogen atoms] [1 Oxygen atom ]. Now the equation becomes. Check if other elements are balanced. Hydrogen is unbalanced with two hydrogen atoms in reactants and four hydrogen atoms in the products. Now make it into four hydrogen atoms by multiplying the hydrogen molecule with two. Now the equation will be. So, there are four hydrogen atoms in both reactants and products and there are two oxygen atoms in both reactants and products.

This means that the chemical equation is balanced. By using the above approach you can balance any chemistry equations. You can find some chemical equation balancing activities in the following links: What is a Chemical Equation? Need for Balancing Chemical Equations When a chemical reaction occurs, the reactants are converted to products.

Steps Now, you know what a chemical equation is and why it should be balanced. Are you sure you want to delete this answer? All other elements are regarded as single atoms and represented by a monatomic symbol in equations as Al, Cu, Fe, Na, etc.

Therefore MgH2 on the right must be doubled. So four H atoms must be shown on the left. Remember that formulas must never be altered in balancing the equation. Atoms can only be balanced by putting a number infront of a formula, thus doubling or trebling the entire formula.

Balancing Chemical Equations Homework. ## Main Topics

Going through the chemical equation, we can conclude that the coefficient in front of H 2 O should be a 6 as it balances all the hydrogens and oxygens out in the equation. The coefficient in front of Hg 3 (PO 4) .
