Homework, balancing equations

[Lonewolfpr0555]

Teachers bombarded us with homework and now I am lost in trying to balance NaHCO​ 3​ (s) → Na​ 2​ CO​ 3​ (s) + CO​ 2​ (g) + H​ 2​ O(g) , can anyone help? Also cant enter it in the solver for some reason either

NaHCO₃ is called sodium bi carbonate or sodium hydrogen carbonate
What does bi mean? It means two.
So you have 2 NaHCO₃ what means Na₂CO₃ + H₂CO₃
Now it is your work to complete the reaction. The products you have already.

Still very confused, if I add the two to that formula then ill have to make the left formula with a 4 which cant add up, There are twelves oxygens now and 4 of everything else, if I solve for everything else to add it up to 4, there will be too many oxygens on the right hand side.

[ChenBeier]

Why you have too. You have only to add the 2 on left side.

2 NaHCO₃ => Na₂CO₃ + H₂O + CO₂

Finished

......My brain died why was I overthinking LOL, thanks.
