1. graph create a graph that illustrates the law of multiple proportions. science notebook · matter—properties and changes 36

Explanation:

Step1: Recall the law of multiple proportions

The law of multiple proportions states that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in the ratio of small whole - numbers. For example, consider carbon and oxygen forming carbon monoxide (CO) and carbon dioxide ($CO_2$). Let's assume we fix the mass of carbon at 12 grams. In CO, 16 grams of oxygen combine with 12 grams of carbon, and in $CO_2$, 32 grams of oxygen combine with 12 grams of carbon. The ratio of oxygen masses (16:32) is 1:2.

Step2: Set up the graph axes

We can set the x - axis as the mass of one element (say element A) and the y - axis as the mass of the other element (element B) that combines with it.

Step3: Plot data points for different compounds

For each compound formed by the two elements, we plot a point on the graph. For example, if we have two compounds $AB_1$ and $AB_2$, we plot the mass of A and the corresponding mass of B for each compound. The resulting graph will show discrete points, and if we draw lines or curves to connect them (if applicable), we can visually see the whole - number ratios of the masses of the elements in different compounds.

Answer:

The graph will have the mass of one element on the x - axis and the mass of the other element that combines with it on the y - axis. Data points for different compounds formed by the two elements are plotted, showing the whole - number ratios as per the law of multiple proportions.
