A chemist is studying the following reaction: SO2 + H2O - H2SO3 K = 2.1 x 10-3 She measures the concentrations of H2SO3 and SO2 and their concentrations are 0.23 M and 0.38 M respectively. Is the reaction at equilibrium? If not, which way must the reaction shift to attain equilibrium?

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
