If a few drops of water are added to a mixture of solid silver nitrate and powdered magnesium the mixture bursts into flames. The water dissolves the silver nitrate to make a highly concentrated solution. An exothermic displacement reaction occurs which ignites any excess magnesium.
In this lab students will conduct an investigation to find out if substance either lose or gain mass after a chemical reaction takes place. Students will combine (and measure the mass of) 200 ml of water with a measured mass of Alka-Seltzer.They will add these two masses together BEFORE combining them.Students will then combine the two substances together in a capped bottle and record observations.tudents will combine (and measure the mass of) 200 ml of water with a measured mass of Alka-Seltzer.
