272cm³ of carbon (iv) oxide were collected over water of 150⁰c and 782mmHg pressure. Calculate the volume of the dry gas at s. t.p? (s. v.p. of water at 150⁰c is 12mmhg)

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system

Ablock of aluminum is dropped into a graduated cylinder with an initial volume of water at 75ml and the volumes rises to 90ml. if the block has a mass of 40.5 g what is its density ?

Aphase change from a solid to a gas is called what
