A reaction which you can produce barium sulphate from barium nitrate. What would be the word equation and a fully balanced chemical equation?

Would the balanced equation be BaNO3 + Na2SO4 ---> BaSO4 + 2NaNO3 ??

Therefore the word equation would be Barium Nitrate + Sodium Sulphate ---> Barium Sulphate + Sodium Nitrate ??

Thank you

Your equation is almost correct.  But the formula for barium nitrate is Ba(NO3)2, not BaNO3.  Barium forms a 2+ ion, and the nitrate anion has a 1- charge, so two of the are needed to balance out the barium.  That makes the chemical equation:

Ba(NO3)2 + Na2SO4 --> BaSO4 + 2NaNO3

Now all of the atoms on both sides of the equation balanced out.  Always remember to count the different atoms on both sides of the equation to see if it is balanced or not.  In terms of the word equation, you are correct.  Barium nitrate plus sodium sulfate gives barium sulfate plus sodium nitrate.

Ok unfortunately Barium Nitrate is not BaNO3, it is Ba(NO3)2. This is because a barium ion has a charge of 2+ while a NO3 ion has a charge of -1, so you need two of them to balance the barium. This is the only problem, the rest is correct. So it is Ba(NO3)2 + Na2SO4 ---> BaSO4 + 2NaNO3


The word equation is right.

Hope this helps :D
