We can use a gas syringe to measure the reaction of metals with dilute acid. When zinc reacts with hydrochloric acid it produces zinc chloride ... when calcium carbonate reacts with dilute ...

A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas ... The positive and negative ions attract each other ...

This activity can get messy; cover all work surfaces. This activity should be done either as a video or a demonstration with the audience at least 10 from the presenter(s). Divide calcium chloride ...
