Calcium carbide can be synthesized using the reaction shown. If a reaction consumes 12 grams of carbon, how many grams of calcium oxide does it consume?

In which situation can a mixture always be called a solution

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
