2 moles of ideal gas at 300K, with an initial volume of 25L, are compressed under an external pressure of 2800 torr. Assuming the temperature and the initial energy of gas do not change, what is the entropy change of this gas? (assume heat flow is reversible)
Imagine that you have a 6.00L gas tank and a 3.50L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
Acetic acid, CH3COOH, is a weak organic acid, pKa 4.47. Determine the position of the equilibrium for the reaction of acetic acid with CH3ONa. Draw the species that predominate at equilibrium. Skip drawing the metal counter ion.
If you dilute 25.0 mL of 1.50 M hydrochloric acid to 500 mL, what is the molar concentration of the dilute acid
