Why does the mentos make the gas come out of soda. The gas is trapped in soda because the water molecules of soda like to “stick” to each other (dipole interactions) and end up around the individual gas molecules. This prevents the gas molecules from joining together to make bubbles. The mentos does …

The other water-soluble unknowns do not react with ammonia. Reaction with Acetic Acid. Like all carbonates, chalk will fizz when treated when acid. Washing soda (main ingredient: Na2CO3, sodium carbonate) and baking soda (main ingredient: NaHCO3, sodium hydrogen carbonate or sodium bicarbonate) will fizz when treated with acetic acid.

Vinegar and Baking soda- Chemical (Considerable formation of gas, bubbling, drop of temperature) ... They decide to react each powder with water, vinegar, and alcohol to see if they can identify the powders based on their physical and chemical properties. They mix 5g of each powder with 5ml of each of the liquids and then record their observations.
