What is the formula antimony trichloride

Harvey mixes two liquids. which observation of the new mixture most likely indicates a precipitate is forming?

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?

Show how to convert the temperature 84.7° c to kelvin. include all steps and label the final answer.
