A 2.50 L sample of methane was collected over water at 28 °C until the pressure in the flask was 775 torr. A small amount of CaSO 4 ( s ) was then added to the flask to absorb the water vapor (forming CaSO 4 -2H 2 O ( s ) ). What is the pressure inside the flask once all the water is absorbed? Assume that the addition of CaSO 4 ( s ) absorbed all the water and did not change the volume of the flask. How many moles of CH 4 ( g ) have been collected?

Please answer the question and provide a detailed drawing of the structure. If there will not be a new C – C bond, then the box under the drawing area will be checked.
Will the following reaction make a molecule with a new C – C bond as its major product:
Draw the major organic product or products, if the reaction will work. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry.
Please do not use AI. AI cannot "see" the molecules properly, and it therefore gives the wrong answer while giving incorrect descriptions of the visual images we're looking at. All of these compounds would be produced (I think). In my book, I don't see any rules about yield in this case, like explaining that one product would be present in less yield for this reason or that reason. Please explain why some of these produce less yield than others.
