Question

1. maya and jordan measured the total mass before and after mixing the smoothie and white powder. using the data in the table and the graph, what does this show?

a. some matter disappeared during the reaction.
b. new atoms were created during the chemical change.
c. the reaction only created a physical change so that doesnt affect the mass.
d. the total mass stayed the same, showing the law of conservation of mass.

1. maya further investigated if temperature effects the rate of reaction. she used smoothies at different temperatures and recorded the time it took for bubbling to start. based on the data table below, what conclusion can she make?

Explanation:

According to the Law of Conservation of Mass, in a chemical reaction, mass is neither created nor destroyed. Measuring the total mass before and after a reaction (mixing smoothie and white powder) and finding it the same would support this law. Option A is incorrect as matter isn't disappearing (violates mass conservation). Option B is wrong because atoms aren't created in a chemical reaction (atomic theory principle). Option C is incorrect as if it were a physical change, there would be no reaction (but the context implies a reaction - mixing substances that might react).

Answer:

D. The total mass stayed the same, showing the Law of Conservation of Mass.
