On a number line, suppose the coordinate of A is 0, and ARequals5. What are the possible coordinates of the midpoint of AR overbar? The possible coordinates for midpoints of the segment are nothing. (Type integers or decimals. Use a comma to separate answers as needed.)

2.5, - 2.5

Explanation:

Given that :

Coordinate of A = 0

and AR = 5 ; distance between A and R

Possible. Coordinate of the midpoint of AR overbar.

Hence for a distance of 5 points between A and R, then R may be located 5 points either side of A, that is to the left of right.

Kindly check attached picture for detailed workings

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
