What is the Percentage of Copper in "Copper" Coins?
Whether in the UK or in the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, just note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in...

Gas Law Investigation
Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...
