You are harvesting sio2, silicon dioxide in order to extract the silicon to use in computer chips. your employer wants to know how much silicon can be obtained from a 500g scoopful of quartz rock, which is pure silicon dioxide. calculate the number of grams of silicon is in the 500g of quartz rock.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).

Define dew point. i am writing this part to be able to ask the question
