A gas has a volume of 28 L, a temperature of 45 degrees C, and an unknown pressure has its volume increased to 34 L and its temperature decreased to 35 degrees C. If I measure the pressure after the change to be 2.01 atm, what was the original pressure of the gas?

Where is the following?

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Are you going to give an example of the plant or?
