This question has multiple parts. Work all the parts to get the most points. Coal and other fossil fuels usually contain sulfur compounds that produce sulfur dioxide, SO2, when burned. One possible way to remove the sulfur dioxide is to pass the combustion gases into a tower packed with magnesium oxide, MgO. Write the equation for the reaction. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not...
