To prepare 100 kg of a solution with 40% salt by mixing two solutions—solution A containing 25% salt and solution B containing 50% salt—the quantity of solution A needed is 40 kg.When 1.2 gram-atoms of carbon reacts with 1.5 gram-moles of oxygen to form 1 gram-mole of carbon dioxide, carbon is the limiting reagent and the excess oxygen supplied is 25%.If a gas bubble at pressure Pg passes through a solvent whose saturation vapor pressure is Ps, and the bubble passage is sufficiently long with air being insoluble, then the mole fraction of solvent in the bubble equals Ps divided by Pg.A supersaturated solution of a sparingly soluble solute with concentration C flows into a crystallizer at volumetric flow rate V. Given the solubility is C1, the solid product output rate from an efficient crystallizer is (C - C1) × V.

Explanation

Option D is incorrect because the rate of solid production from the crystallizer should be based on the difference between the feed concentration and solubility, i.e., (C - C1) × V, not the sum (C + C1) × V. The other statements are accurate based on the given chemical and physical principles.
