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.

The change that took place is a chemical change as a chemical reaction occurs.

Vinegar =

Baking soda =

Reaction:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

that tool would be a compass
