Show the complete set-up with detailed calculation. a. 32g of solid sulfur (S) reacts with oxygen gas (O2) in a closed container producing 80g of sulfur trioxide (SO3). The reaction obeyed the law of conservation of mass. What is the amount of oxygen gas that reacted? S+O2(gas)SO3(gas) 1) Calculation: 2) Predict what would happen to the mass of the reactants and products, if the reaction was done in an open container. In an opon contuiner, the gas produced will escape. So this would change the tuted muss Insicle the container b. A student measures 10.5g of mercury (II) oxide into an open test tube and heats the tube. The heat causes the mercury (II) oxide to decompose into mercury and oxygen gas. After the reaction, the student finds the mass of the contents of the tube to be 9.7g. Which one of the following describes these observations? 1) The decomposition of mercury (II) oxide does not obey the Law of Conservation of Mass. 2) 10.7 grams of mercury are produced. 3) There are errors associated with the student's measurement. 4) 0.8 grams of oxygen are lost from the tube.
