Cloth can be waterproofed by coating it with a silicone layer. This is done by exposing the cloth to (CH3)2 SiCl2 vapor. The silicon compound reacts with OH groupson the cloth to form a waterproofing film (density = 1.0 g/cm³) of [(CH3)2 SiO], where n is a large integer number.n (CH3) SiCl2 + 2n OH → 2n Cl + n H₂O + [(CH3)2 SiO] nThe coating is added layer by layer, with each layer of [(CH3)2 SiO], being 0.60 nm thick. Suppose you want to waterproof a piece of cloth that is 4.00 squaremeters, and you want 250 layers of waterproofing compound on the cloth.

Bacterial digestion is an economical method of sewage treatment. The reaction is an intermediate step in the conversion of the nitrogen in organic compounds into nitrate ions. What mass of bacterial tissue is produced in a treatment plant for every 1.0 104 kg of wastewater containing 3.0% NH4+ ions by mass? Assume that 95% of the ammonium ions are consumed by the bacteria.
You take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.
