Calculate the work done when 50.0g of tin dissolves in excess acid at 1.00atm and 25 (degree in celsius)Sn(s)+2H(aq)----- Sn(aq) +H2(g)Assume ideal gas behavior The work done = (pressure)*(increase in volume)The increase in volume is due to the H2 gas created. 50 g of tin (Sn) is 0.421 moles. That is also the number of moles of H2 that are created. Use tha ideal gas law to compute the added volume due to that gas.
A 388 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 640. mmHg. Calculate the moles of Ar present.
chemicals x and y react to form the gas xy but it takes some time for the reaction to occur. both x and y are placed in a container with a piston and you note the volume. As the reaction occurs, what happens to the volume of the container? explain..
