During an experiment vinegar was added to baking soda. The following observations were recorded. Observation 1: The container with the reaction mixture feels cooler. Observation 2: Gas bubbles are released. Based on the observation, justify the type of change (physical or chemical) that took place.

Baking soda reacts with the vinegar to produce carbon dioxide gas, sodium acetate, and water. ... Since more energy was needed to break the baking soda and vinegar apart, the temperature went down( endothermic reaction.

Observation 1. In this observation, the temperature is being decreased because this reaction is an endothermic process. As there is change in temperature, hence it is considered as a chemical change.

Observation 2: In this observation, gas bubbles are formed due to the release of carbon dioxide gas. As there is formation of bubbles in this reaction. Hence, it is considered as a chemical change.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?
