c. If the video shows the burning of 1.80 grams of sugar with 1.92 grams of oxygen gas, what would Aria and Marcus expect the total mass of all the products (including the gases) to be? Why?

You can use the calculator (below the answers) if desired.

The total mass of the products would be something less than 3.72 grams, because some of the mass burned into nothing.

The total mass of the products would be greater than 3.72 grams, because water is really heavy.

The total mass of the products would equal 1.80 grams, because the mass of oxygen gas doesn't make a difference.

The total mass of the products would be 3.72 grams, because mass cannot be gained or lost in the process.

The correct response is:

The total mass of the products would be 3.72 grams, because mass cannot be gained or lost in the process.

This is in accordance with the law of conservation of mass, which states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products. In this case, when 1.80 grams of sugar is burned with 1.92 grams of oxygen, the total mass of the reactants is 3.72 grams, and thus the mass of the products will also be 3.72 grams.

b. How do you expect synthetic materials to compare to the natural resources used to make them?

The correct response is:

The synthetic materials have different properties from the raw materials because chemical reactions took place.

Synthetic materials are often created through chemical processes that change the structure and properties of the original raw materials. As a result, the synthetic materials exhibit different physical and chemical properties compared to the natural resources from which they were derived.
