Na2S2O8 + NaOH = Na2O4S + H2O2 Recently Balanced EquationsBalance C2H7N + O2 = CO2 + H2O + N Using the Algebraic Method To balance the equation C2H7N + O2 = CO2 + H2O + N using the algebraic method step-by-step, you must have experience solving systems of linear equations. The...
H72❌ N11✔️ O25❌ We could not determine all the steps needed to balance the equation using trial and error. This may mean it requires too many steps and the chemical equation is too complex to use this method, or that the equation is invalid (e.g. has 0 or non-integ...
The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in Ca(CH3COO)2 + (NH4)2CO3 = CaO + C...
