The chemical formula (not equation) of sodium hydrogen sulfite is NaHSO3.
H2SO4 + 2NaOH ---> Na2SO4 + 2H20 sulphuric acid + sodium hydroxide ----> sodium sulphate + water
1/2H2(g) + 1/2F2(g) -> HF(g)
A balanced equation has equal numbers of each type of atom on each side of the equation.The Balanced Ionic equation for Nitrous acid and sodium hydroxide is as follows .Nitrous acid is a weak acid so it does not completely dissociate in water. So you can write for the net ionic equation :HNO2 + OH- ---> NO2- + H2O

The chemical formula (not equation) of sodium hydrogen sulfite is NaHSO3.
Word equation:sodium + oxygen => sodium oxideSymbol equation:4Na + O2 => 2Na2O
CH3CHO+HCl
Na2CO3.10H2O --> Na2CO3 + 10H2O
Sodium (Na+) and Hydrogen (H+) do not mix because they are both positively charged.
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
To solve Hess's law problems, first write out the chemical equations for all reactions involved. Then calculate the enthalpy change for each reaction. Finally, add or subtract the enthalpy changes to obtain the overall enthalpy change for the desired reaction.
H2SO4 + 2NaOH ---> Na2SO4 + 2H20 sulphuric acid + sodium hydroxide ----> sodium sulphate + water
Na2O + CO2 >> Na2CO3Balanced. Single displacement, I think. SYNTHESIS
CH3COONa + NaOH ----(CaO + heat)-----> CH4 + Na2CO3
1/2H2(g) + 1/2F2(g) -> HF(g)
