Look at this image what type of galaxy is shown? A. barred B. elliptical C. irregular or D. spiral.

Spiral

Explanation:

I searched up each one and the spiral was the exact picture of that. The irregular galaxy doesn't really have a shape to it. The elliptical galaxy is more smooth and less defined. As in you can't really see as many stars. And the barred galaxy is more oval shaped, kind of like an eye.

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.
