Mass of evaporating dish #1: 35.687 g, Mass of evaporating dish #1 and dry sand: 36.122 so, what is the mass of sio2 (g) and percent by mass of sio2(%).

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
