Identify between a real gas and ideal gas

1.Ideal gas has no definite volume while real gas has definite volume. 2.Ideal gas has no mass whereas real gas has mass. 3.Collision of ideal gas particles is elastic while non-elastic for real gas. energy involved during collision of particles in ideal gas.

Explanation:

hope this helps

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.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
