Consider firstly if there are equal numbers of atoms of each element on either side of the reaction. No, there aren't: there are too many sodium, chloride ions and hydrogen atoms on the reactant side, so the equation is not balanced.
Na2S is not an equation in itself. However, it is a molecule with zero charge, which is what I think you are getting at.
Yes
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
H2so4
The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
bak+si
Br2 + Zn ----> ZnBr2
It is balanced.
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
When the equation kmno4 plus mgs k2s plus mgmno42 is balanced, the correct set of coefficients is 2111.
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
H2so4
C+ 2H2--> CH4 is the balanced equation.
I believe it is already balanced. No coefficients neccessary
The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
HCl + NaOH = H2O + NaCl is already balanced.
No, it is not.
