A cotton swab is dipped into concentrated hydrochloric acid (producing hydrogen chloride gas) while a second on is dipped into concentrated aqueous ammonia (producing ammonia gas). Both cotton swabs ...

Outline a plan to investigate how the rate of this reaction changed when the concentration of the hydrochloric acid was changed. Describe how you would do the investigation and the measurements ...

The sodium reacts most vigorously with the nitric acid, producing a flame and smoke. The sodium also reacts pretty strongly with the weaker concentration of hydrochloric acid. The demonstration shown ...
