why is dissolving sugar into water a physical change? they form a compound they form a new substance they taste good they can be separated physically multiple choice 1 point what is causing the bubbles to form when mixing baking soda and vinegar? more vinegar is created the chemical reaction between the two substances more baking soda is created water is being released as it is boiling

Explanation:

1. Dissolving sugar in water is a physical change because the sugar and water can be separated physically (e.g., through evaporation), and no new chemical substance is formed. A compound is a new chemical - bonded entity, and taste is not related to the nature of the change.
2. When baking soda (sodium bicarbonate) and vinegar (acetic acid) are mixed, a chemical reaction occurs. This reaction produces carbon dioxide gas which is seen as bubbles. No new vinegar or baking soda is created, and it is not related to water boiling.

Answer:

1. They can be separated physically
2. the chemical reaction between the two substances
