In experiment on the effect of heating on oxides of lead in a current of hydrogen the following results were obtained. Show that they are in agreement with the law of multiple proportions.
a. `1.393 g` of litharge `(PbO)` gave `1.293 g` of lead
b. `2.173 g` of lead peroxide `(PbO_(2))` gave `1.882 g` of lead
c. `1.712 g` of red lead `(Pb_(3) O_(4))` gave `1.552 g` of lead

To show that the results of the experiment on the oxides of lead are in agreement with the law of multiple proportions, we will follow these steps: ### Step 1: Calculate the mass of oxygen in each oxide We will find the mass of oxygen that was released when each oxide was heated. 1. **For PbO (litharge)**: - Mass of PbO = 1.393 g - Mass of lead obtained = 1.293 g ...
