ziploc chemical equation

For the observing changes lab (ziplock lab) we combined baking soda and calcium chloride. Use the internet to complete the chemical equation:


calcium chloride + sodium bicarbonate → _____________________

or

CaCl2 + 2 NaHCO3 → _________________________

Quick Review

What have you learned about copper sulphate crystals and how to make them? Do you think this is a physical or a chemical change? Why?


What did you learn from the ziplock lab or the youtube clip about cabbage indicators? Why do you think that in both, things turned colour? Was this a physical or a chemical change? Why?
