You'll get a detailed solution from a subject matter expert that helps you learn core concepts. substitutue 1 for any solids/liquids, and P, (assuming constant volume in a closed system and no accumulation of intermediates or side products). For a complete tutorial on balancing all types of chemical equations, watch my video:https://www.youtube.com/watch?v=zmdxMlb88FsImportant tips for balancing chemical equations:- Only change the numbers in front of compounds (the coefficients).- Never change the numbers after atoms (the subscripts).- The number of each atom on both sides of the equation must be the same for the equation to be balanced. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
