NaHCO yeilds NaOH + CO2, How do you balance this equation

NaHCO_3 \rightarrow NaOH + CO_2

Write the correct formula of sodium hydrogen carbonate.

Count the number of Na, C, H and O on both hand sides. If they are the same, the equation is balanced. If not, try to balance them first. If you still can't do it, post where you are stuck, like which of the 4 elements you are not able to balance.
