I get that you’re supposed to balance; however, I was confused on how to do the reduction and oxidation electron equations (the simplist way). Looked at too many examples online but nothing was clear. 1) Cu + HNO3 → Cu(NO3)2 + NO2 + H2O 2.) KMnO4 + H2SO4

balance the equation:(i can balance the equation but the problem i have is finding the formula for the last part HC2H3O2(aq) + Ca(OH)2(aq) -> H2O(l) + find the formula here the last part would be CaOC2H3O2? im a little confused. did the O fromt he H2O come

Is this balanced correctly NaOH + H2SO4 = Na2SO4 + H2O? In this equation, Sodium (Na) and Hydrogen (H) atoms are not balanced. There are 2 atoms of Sodium (Na) on Right Hand Side, so we can multiply NaOH with 2 on Left Hand Side. This balances the Sodium
