First, be sure to count all of ca, o, and c atoms on each side of the chemical equation. For instance equation c6h5c2h5 + o2 = c6h5oh + co2 + h2o will not be balanced, but phc2h5 + o2 = phoh + co2 + h2o will; Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are, enter reagents only and click 'balance'. In many cases a complete equation will be suggested. Reaction of ca (canxi) react with o2 (oxi) produce cao (canxi oxit) ,temperature condition > 300 reaction that produces substance ca (canxi) (calcium) cacl 2 → ca + cl 2 cas → ca + s cah 2 → ca + h 2 reaction that produces substance o2 (oxi) (oxygen) 2cu (no 3) 2 → 2cuo + 4no 2 + o 2 2kno 3 → 2kno 2 + o 2 2agno 3 → 2ag + 2no 2 + o 2
