If the pressure, volume, and temperature of a gas are known, wh ich can most likely be found by using the ideal gas law?
the molar amount of the gas
the partial pressure of the gas
the standard temperature and pressure
the molar mass

heat or electricity in the atmosphere- c.

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.
