How to Balance Chemical Equations (Initial) Step 1: Coefficients Versus Subscripts. When approaching a chemical equation, it is important that you understand the difference between coefficients and subscripts.Step 2: Sum the Atoms.Step 3: Balance the First Element.Step 4: Repeat for the Other Elements.Step 5: Tips.

Pb + H3PO4 = H2 + Pb3(PO4)2 might be a redox reaction.

How to Balance Pb + H3PO4 = H2 + Pb3(PO4)2 (Lead + Phosphoric acid) YouTube Start of suggested clip End of suggested clip So let's balance the phosphates. If we put a 2 here. Now we have 1 phosphate times the two. So thatMoreSo let's balance the phosphates. If we put a 2 here. Now we have 1 phosphate times the two. So that balances the phosphates.

How to Balance Na3PO4 + HNO3 = H3PO4 + NaNO3- YouTube YouTube Start of suggested clip End of suggested clip Let's balance the hydrogens. Next we could put a three in front of the nitric. Acid. One times threeMoreLet's balance the hydrogens. Next we could put a three in front of the nitric. Acid. One times three that'll give us three hydrogen atoms those are balanced. And then the one nitrate one no3.

If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.

Identify the reactants, products and their formulae. Write the main part of the equation. Determine the number of atoms of each element on both sides of the equation. The numbers of atoms are not balanced.
