During chemistry lab, Mrs. Black’s students placed an antacid tablet in a zip lock bag. They recorded the mass of the tablet in the bag. Then they carefully added 50 grams of water and quickly sealed the bag. The tablet began to fizz and soon disappeared. The bag was filled with gas and it felt cold to the touch.
What type of change occurred in the bag and how can you support your answer?
A) It is a physical change because the tablet dissolved.
B) It is a physical change as evidenced by change in temperature.

The type of change that occur is: C) It is a chemical change due to the change in temperature and gas production.

One of the indicators of a chemical change is that when two reactants mix together, their reaction produces a new substance as temperature of the mixture changes.

This temperature change in a chemical change is different from that of temperature change in a physical change.

In a physical reaction where temperature changes, new substances of a different composition are not formed, but in a chemical change involving change in temperature, new substances are formed.

The reaction of the tablet with water produces a new substance, which is a gas, with a change in temperature.

Therefore, we can conclude that: it is a chemical change due to the change in temperature and gas production.
