Which chemical equation is balanced? To balance the amount of H on both sides, we have to multiply H2 (on the left side) by 2. I think. Examples: Fe, Au, Co, Br, C, O, N, F. Therefore, the entire equation is multiplied by 2 to eliminate the fraction in front of O2. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. BBBBBBB It makes the hydrogen 4 on the reactants side. 5. H2S + O2 → H2O + SO2 Number of each atom on the reactant side: H is 2; S is 1; O is 2 Number of each atom on the product side: H is 2; S is 1; O is 3 Therefore, oxygen is out of balance. 2H2 + O2 → 2H2O. This is the balanced equation, nothing wrong with that except the fraction front of O2. For eg, Na + Cl ---> NaCl (this is balanced because there's 1 Na in reactant and 1 in product, and same case for chlorine) H2 + O2 > H2O (This is not balanced because there's two oxygen on reactant and only one on product so we multiply h2o by two and H2 by 2) Share with your friends. When a two is added in front of the H2O there are now two oxygen atoms on both sides. Therefore, atoms that are present on one side of the equation must be present on the other side as well. 5. AAAAAAA How many oxygen atoms are there now? 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. Reactant Product This equation is unbalanced. This means for 1 mol oxygen we need 2 moles of H2 … In CuSO4 , Cu is in the oxidation state of +2 which is converted to metallic state (oxidation number 0). CO2 + H2O. Identify all of the phases . Now the equation looks like, C8H18 + 25/2 O2 Æ 8 CO2 +9 H2O . This equation will never balance. Both sides must be balanced. Thus, H2 + O2 -> 2H2O . SO2 + HF. 2Fe+O2+H2O=Fe2O3+H2. P4 + O2 !
