The data table is from a lab in which an effervescent tablet is added to a test tube of water.
This produced a solution that fizzes and releases gas bubbles that escape into the air.
The total mass of the substances and the test tube were recorded before and after the tablet was added to the test tube of water.
If matter is always conserved, how do you explain these results?
