2Na + 2H2O -> H2 + 2NaOH
The balanced equation for Na2O + H2O → 2 NaOH is: Na2O + H2O → 2 NaOH
2Na + 2H2O -------> 2NaOH + H2
HCl + NaOH = H2O + NaCl is already balanced.
my balance sheet does not balance why?
The chemical equation is:Sn + 4 HNO3 = SnO2 + 4 NO2 + 2 H2O
HCl + NaOH --> Na2SO4 + H2O You're missing something there... There's sulfur in the products but not in the reactants. And chloride in the reactants but not in the products... More likely you meant HCl + NaOH --> NaCl + H2O Which is already balanced.
To balance the equation between propionic acid (C3H6O2) and sodium hydroxide (NaOH), you need to form water (H2O) and sodium propionate (C3H5NaO2). The balanced equation is: C3H6O2 + NaOH -> H2O + C3H5NaO2. This equation is already balanced because there is an equal number of each type of atom on both sides of the equation.
2 NaOH + SO2 = H2O + Na2SO3
The reaction between NaOH and HCl produces NaCl (sodium chloride) and H2O (water). The balanced chemical equation is: NaOH + HCl → NaCl + H2O.
To balance the reaction between NaOH and H2SO4, you first write out the unbalanced equation: NaOH + H2SO4 -> Na2SO4 + H2O. To balance it, you need to ensure the same number of atoms of each element on both sides of the equation by adjusting the coefficients. In this case, you would need to put a coefficient of 2 in front of NaOH to balance the equation: 2NaOH + H2SO4 -> Na2SO4 + 2H2O.
HCl + NaOH = NaCl + H2O
Na3PO4+H2O->NaOH+H3PO4 just balance it.
