Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water.(d) Ca(OH)2(s) ® CaO(s) + H2O(l). (e) 2NaCl(s) + H2SO4(l) ® Na2SO4(s) + 2HCl(g). Plaster of Paris, CaSO4∙1/2H2O(s), reacts with liquid water to form gypsum. CaSO4∙2H2O(s). Write a chemical equation for the reaction and calculate ∆Go in kJ using the date in the Table of Standard Free Energies.CaCO3(s) + 2HCl(aq) CaCl2(s) + H2O(l) + CO2(g). Each reaction started with 2 mol of HCl with excess calcium carbonate. As you can see from the graph, the rate of reaction tails off towards the end, as the HCl is being used up, i.e. its concentration is decreasing.#"CaO"_ ((s)) + color(red)(2)"HCl"_ ((aq)) -> "CaCl"_ (2(aq)) + "H"_ 2"O"_ ((l))#. You need #color(red)(2)# moles of hydrochloric acid for every mole of calcium oxide that takes part in the reaction. You an convert this mole ratio to a gram ratio by using the molar masses of the two compounds.
