If there were 197g of sulfuric acid in your car battery, how many grams of baking soda would you need to completely neutralize the acid. Here is the balanced equation: H2SO4(aq) + NaHCO3(s)....NaSO4(aq) + 2CO2(g) + 2H20(l)
This is worked the same way as your other ost (the Ni problem).
The equation you have written is not balanced and Na2SO4 is sodium sulfate and not NaSO4.
