A typical formulation for window glass is 75% SiO₂, 15% Na₂O, and 10.% CaO by mass. What masses of sand (SiO₂),sodium carbonate, and calcium carbonate must be combined toproduce 1.00 kg of glass after carbon dioxide is driven off bythermal decomposition of the carbonates?

A 244.5-g sample of ground water is analyzed for calcium. The Ca2+ in the sample is first precipitated and filtered-off as NH4CaPO4.7H20. This precipitate is dried and heated, releasing water and ammonia to yield anhydrous calcium pyrophosphate (CaP2O7). The mass of CaP2O, obtained is 0.0419 g. Give the calcium content of the ground water in parts per million (to three significant figures).
Ancient Romans built often out of bricks and mortar. A key ingredient in their mortar was quicklime (calcium oxide), which they produced by roasting limestone (calcium carbonate). 1. Write a balanced chemical equation, including physical state symbols, for the O-0 decomposition of solid calcium carbonate (CaCO2) into solid calcium oxide and gaseous carbon dioxide. da 2. Suppose 50.0 L of carbon dioxide gas are produced by this reaction, at a temperature of 400.0 °C and pressure of exactly 1 atm, Calculate the mass of calcium carbonate that must have reacted.
