When a 0.3445 gram sample of solid calcium (ca) was burned in a constant-volume calorimeter (bomb calorimeter) with a measured heat capacity of 0.1975 kj/°c, the temperature of the calorimeter increased by 27.63°c. (a) calculate the change of heat released by the combustion of the calcium sample. kj (b) determine the change of heat that would be released by the combustion of 1 mole of calcium.

Why do cells appear different in distilled water than they do in 10% salt water?

What happens when an atom of sulfur combines with two atoms of chlorine to produce sci2? a. each chlorine atom shares a pair of electrons with the sulfur atom. b. an electron is transferred from each chlorine atom to the sulfur atom. c. an electron is transferred from the sulfur atom to each chlorine atom. d. each chlorine atom shares all its valence electrons with the sulfur atom.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
