Question #4e3aa

Answer 1

You would see a rapid foaming caused by the evolution of a colourless gas.

Explanation:

The gas is carbon dioxide (`"CO"_2`).

It is formed by the action of sulfuric acid on the baking soda.

`underbrace("H"_2"SO"_4"(l)")_color(red)("sulfuric acid") + underbrace("2NaHCO"_3"(s)")_color(red)("baking soda") → underbrace("Na"_2"SO"_4"(aq)")_color(red)("sodium sulfate") + underbrace("2H"_2"O(l)")_color(red)("water") + underbrace("2CO"_2"(g)")_color(red)("carbon dioxide")`
