Given the equation 2 co + o2 —> 2co2, how many grams of co2 form if 34.0 grams of co are combined with excess oxygen? a) 53.4 b) 21.6 c) 145 d) 107 this question is really confusing to me, and i’m not even sure how to go about answering it.

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

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
