What volume of carbon dioxide is produced when 23.1 g of calcium carbonate reacts completely according to the following reaction at 25 °C and 1 atm? calcium carbonate(s) → calcium oxide(s) + carbon dioxide(g) L Volume =

a 2.802g sample of an unknown pure metal (M) is added to a 0.2 L solution of 2 mol/L H2SO4(aq). The metal reacts with the acid until the metal is completely gone to form M3+(aq) ion in the solution and produces hydrogen gas that is collected. The hydrogen gas that is collected over water that is isolated from the reaction has a volume of 0.82 L at 25 degrees Celsius and a total pressure of 704.0 mmHg. How many moles of H2(g) are produced? Write a balanced equation for the reaction of M with H2SO4(aq). What is the identity of metal M?

A cylinder is filled with  10.0L  of gas and a piston is put into it. The initial pressure of the gas is measured to be  147.kPa . The piston is now pulled up, expanding the gas, until the gas has a final volume of  72.0L . Calculate the final pressure of the gas. Round your answer to  3  significant digits.
