It seems obvious that the bubbles look blue in the cup because the soda bubble walls are thinned, and it's a trick of the light. However, it could also be that you put ice in the cup before pouring the soda in, in which case it's just that the soda is watered down.
Heating a cup of tea is a physical change, not a chemical change. The heat causes the molecules in the tea to move faster, but the chemical composition of the tea remains the same.
When a cup of hot tea cools down, it is a physical change, not a chemical change. The molecules in the tea are simply rearranging as the temperature drops, but the chemical composition of the tea remains the same.
For the best chemical reaction in a volcano experiment, use about 1/4 cup of vinegar and 1 tablespoon of baking soda.
The hypothesis for the "lava in a cup" experiment may be that when vinegar (acid) is added to baking soda (base), a chemical reaction will occur and produce carbon dioxide gas, which will create bubbly "lava" in the cup.

To unclog a drain effectively using baking soda, start by pouring 1 cup of baking soda down the drain. Follow this with 1 cup of vinegar. Let the mixture sit for about 30 minutes, then flush the drain with hot water. Repeat if necessary. The chemical reaction between the baking soda and vinegar can help break down clogs and clear the drain.
Yes, as in pouring a cup of tea.
To effectively unclog a drain using baking soda and vinegar, start by pouring boiling water down the drain to loosen any debris. Then, pour 1/2 cup of baking soda followed by 1/2 cup of vinegar down the drain. Let it sit for about 30 minutes, then flush the drain with hot water. Repeat the process if needed. The chemical reaction between the baking soda and vinegar can help break down clogs and clear the drain.
To effectively unclog sinks using baking soda, start by pouring 1 cup of baking soda down the drain. Follow this with 1 cup of vinegar and let it sit for 30 minutes. Then, flush the drain with hot water to help clear the clog. Repeat if necessary.

To effectively clear a drain using baking soda, start by pouring about 1 cup of baking soda down the drain. Follow this with 1 cup of vinegar. Let the mixture sit for about 30 minutes, then flush the drain with hot water. This combination can help break down clogs and remove debris from the drain.
To effectively unclog a drain using baking soda and salt, start by pouring half a cup of baking soda down the drain, followed by half a cup of salt. Let it sit for a few hours or overnight, then pour boiling water down the drain to flush out the clog. Repeat if necessary.
To effectively unclog a kitchen sink using baking soda, start by pouring 1 cup of baking soda down the drain. Follow this with 1 cup of vinegar and let it sit for about 30 minutes. Then, flush the drain with hot water to help clear the clog. Repeat the process if necessary.
