What is a Balanced Chemical Equation?
A balanced chemical equation means that there are an equal number of atoms on both sides of the reaction. Since matter cannot be created or destroyed then there must be the same amount coming out of the reaction as there was going into it. Read More »

What is a balanced chemical equation for this reaction?
lead(II) nitrate = Pb(NO3)2 Sodium Sulfate = Na2(SO4) lead(II) sulfate = Pb(SO4) So we have: Pb(NO3)2 + Na2(SO4) --> Pb(SO4) + 2Na(NO3) Since we had two nitrates and two sodium on the right, we needed two of each on the left. Other wise thi... Read More »
