Write the formula for Tums? How does Tums chemically react with water and stomach acid?
Tums - CaCO3 ---> Ca + CO3
Tums, water, stomach acid - CO3 + H ---> HCO3 + H ---> H2CO3 ---> <--- H2O + CO2

How many Tums are needed to neutralize a can of coke?

Quite a bit to meet the pH changes because the pH is about 2 so you would need to take more than 4 tums.
