Answer 4

which statement correctly describes the relationship between thermal energy and particle movement?

as thermal energy increases there is less particle movement
as thermal energy increases particle movement does not change
as thermal energy increases it is not possible to predict particle movement
as thermal energy increases there is more particle movement

Answer 5

[AI-generated answer — Bot GPT 3.5]

The statement that correctly describes the relationship between thermal energy and particle movement is: as thermal energy increases, there is more particle movement.

Answer 6

what happens to the density of a material if you have a larger piece of it?

A: the density will be smaller because the mass Remains the Same as the volume increases
B: the density will remain the same because the mass and volume will remain the same
C:the density will remain the same because the mass and volume will both increase in the same way
D:the density will be greater because the mass increases but the volume Remains the Same

Answer 7

[AI-generated answer — Bot GPT 3.5]

The answer is C: the density will remain the same because the mass and volume will both increase in the same way.

Answer 10

sodium reacts with chloride to form the compound sodium chloride or salt. if the total mass of the reactants is 58.44 AMU what will be the total mass of the products

60 amu
116.88 amu
58.44 amu
29.22 amu

Answer 11

[AI-generated answer — Bot GPT 3.5]

The correct answer is: 58.44 amu. The total mass of the products will be equal to the total mass of the reactants in a chemical reaction, according to the law of conservation of mass.
