Convert particles to moles: 3.2 x 10^30 molecules NaCl

An electrons position cannot be known precisely only it's probability of being in a certain location can be known

Convert the temperature of dry ice, –77 ∞c, into degrees fahrenheit and kelvin.

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?
