In acid and base neutralization reaction 22.41 mL of 0.1273 M calcium hydroxide neutralizes 16.35 mL of HCI Calculate molarity (M) of HCI. Given reaction: Ca(OH)2 (aq) + 2HCl (aq) CaCl2 (aq) + 2H20 (1)

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?
