Students are designing an experiment to test the law of conservation of mass using the following materials: 10 g baking soda, 30 mL vinegar, an electronic balance, and a resealable plastic bag. Describe the basic procedure the students should follow to model this law. (kinda make it a 7th grade level answer)

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
