Please answer this question on a blank piece of paper, ensuring to show all of your work On December 21, 2020, Saturn and Jupiter aligned so closely in the night sky that they almost appeared to collide from our vantage point on Earth, creating a single radiant point of light. The last time this alignment, known as the Great Conjunction, was seen on Earth was March 4, 1226. The conditions on the surface of these two planets are very different than those on Earth. On Saturn, atmospheric pressure is 0.987 atm and the average temperature is 135K, and on Jupiter, the pressure at the same altitude is 10.0 kPa and 110 K. a. What is the density of CO2(g) on Jupiter? (3 marks) b. What is the volume of 4.25 g of CO2(g) on Saturn? (4marks)

Please complete this question on a blank piece of paper, ensuring to show all of your work. Historically, lead(II) nitrate was used to prepare pigments such as chrome yellow, PbCrO4(s). To prepare the pigment, aqueous solutions of lead(II) nitrate were reacted with aqueous solutions containing sodium chromate as represented by the following balanced equation. Pb(NO3)2(aq) + Na2CrO4(aq) → PbCrO4(s) + 2 NaNO3(aq) NOTE: due to the toxic nature of lead compounds, pigments no longer contain lead. a. What mass of chrome yellow, PbCrO4(s), could be prepared by adding a solution containing 200.g of lead(II) nitrate to a solution containing 150.g of sodium chromate? (6 marks) b. What mass of excess reagent will remain? (4 marks)
