A '5.0 L' tank of helium, which is kept at a pressure of h5.0 MPa (1 MPa or megapascal = 1000 kPa) in a room with a temperature of 22.0°C, is used to blow up
balloons. The balloons, when inflated, have a volume of 2.0 L and maintain a
pressure of 115 kPa without breaking. If the temperature remains constant, what
is the maximum number of balloons that can be filled with this tank?

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
