We're told oxygen is the most common element in the Earth's solid crust. But how much oxygen is there? Let's compare to the amount of oxygen in the Earth's atmosphere, like this: • The most common minerals in the Earth's crust are feldspars, and sanidine (KAISI,O,) is a typical feldspar. Let's assume the entire crust is made of sanidine, with a density of 2.5 g/cm³. • The radius of the Earth is 6371. km and let's say the crust is the upper 75.0 km of it. • Let's model the Earth's atmosphere as a layer on top of the Earth about 100. km thick with an average density of 0.99 g/m°, and which is 23.1% oxygen by mass. Use this information to calculate the ratio of the mass of oxygen in the Earth's atmosphere to the mass of oxygen in the Earth's crust. Round your answer to 2 significant digits.

A chemical element “A" reacts with HNO, to give a solution of compound "B". Thermal decomposition of “B" yields a yellow compound "C". Heating of "C" in oxygen at 500 °C gives a red compound "D" (the mass of the solid is increased by 2.4%) (confirm by calculations). Compound "D" can react with concentrated hydrochlorie acid producing a yellow-green gas and a compound "E". When “D" reacts with the glacial acetic acid, a white crystalline “F" is produced as well as a solution of compound "G". When Cl, gas is passed through the solution of "G", an additional amount of "F" can be produced. When H,S gas is passes through the solution of “B", a black precipitate “H" forms. The latter reacts with H,O, yielding a white compound "I" Determine the molecular formulas of compounds “A"-"I" and write the chemical equations for all mentioned reactions. O2, 500 °C HCI(conc.)
