Compound states [like (s) (aq) or (g)] are not required. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Chemistry Chemical Reactions Chemical Equations. Login to reply the answers Post; Martin S. Lv 7. Rate! So you have to balance charge and elements. Comments; Report Log in to add a comment gayatribaviskar979 Ace; The second equation is unbalanced that is Sr + O2 2SrO Balanced equation will be 2Sr + O2 2SrO HOPE IT WILL HELP YOU MARK IT AS BRAINLIEST... 3.9 7 votes 7 votes Rate! Input Equation Balanced Equation; Al+I2 = AlI3: 2Al + 3I2 = 2AlI3: Ag2S+H2 = Ag+H2S: Ag2S + H2 = 2Ag + H2S: Al (s) + Cl2 (g) = AlCl3 (s) 2Al(s) + 3Cl2(g) = 2AlCl3(s)

#O_2# is one oxygen molecule - there is only one oxygen atom in #H_2O#. Write the balanced chemical equation for the reaction NaOH + HCI --> NaCI + H20 2.

You can use parenthesis or brackets []. Compound states [like (s) (aq) or (g)] are not required. 2H2 + O2 -> 2H2O What is the percent yield of H2O if 87.0 g of H2O is produced by combining 95.0 g of O2 and 11.0 g of H2? #2H_2O_2->2H_2O+O_2# 2H2 + O2 -> 2H2O balanced Now, one H2 on the left and two H2 on the right, then. 1.

How To Balance Equations Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

Explanation: There are 4 hydrogen and 2 oxygen on the reactants side. Balanced equation: 2 H2 + O2 --> 2 H2O Balance the following chemical equation Na plus H2O ----- NaOH plus H2? ____ H2 + ____ O2 ---> ____ H2O. Sr + O2 2SrO 6H2 + 3O2 6H2O H2 + H2 + O2 H2O + 2 See answers Answers mukherjisoumi31 Ace; Full wrong question..... 1.0 6 votes 6 votes Rate! Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. You can use parenthesis or brackets []. I think question is balance H2O and e- to OH- and H2. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. To balance the equation the number of molecules of each element have to be equal on both sides: 2H2O ==> 2H2 + O2 How do you balance the equation for H2 plus o2-h2o? 3 Hydrogens on one side so use 2 H2O. Replace immutable groups in compounds to avoid ambiguity.

Read our article on how to balance chemical equations … The balanced equation will appear above. What is the balanced equation for the chemical reaction #Mg_3N_2+2H_2O -> Mg(OH)_2+NH_3#? Then use 2 OH- to make 4 Hydrogens and 2 oxygens on each side. Products H - 2 O - 1. 2H2 + O2 → 4H2O 4Na + O2 → 2Na2O Fe2O3 + H2 → 2Fe + 3H2O CH4 + O2 → CO2 + H2O 2 See answers Answer 2.8 /5 2. ellieemberton +6 hendikeps2 and 6 others learned from this answer Answer: The first one. How To Balance Equations.

1 Answer Paul May 31, 2014 The answer is: #H_2 + 1/2O_2 -> H_2O# Cut the equation in half: Reactants H - 2 O - 2. You are going to want a high temperature and a catalyst for this to work well.
