Answer 1

a. Does this make sense? Why or why not?

Response: Yes, it makes sense, because we expect products and reactants to have different properties.

Explanation: In chemical reactions, it is common for the reactants and products to have different physical and chemical properties, including boiling points. The decomposition of hydrogen peroxide into water and oxygen involves breaking and forming chemical bonds, leading to new substances with distinct properties.

b. How would you expect the density of water to compare to the density of hydrogen peroxide?

Response: It is most likely that the density of water would be different from the density of hydrogen peroxide.

Explanation: Although both substances are liquids, they are composed of different molecules, which typically results in different densities. Hydrogen peroxide (H₂O₂) tends to have a higher density than water (H₂O), given that it has a greater molar mass due to the presence of an additional oxygen atom.
