Determine the enthalpy change of the following reaction: 2kclo3 -> 2kcl + 3o2 given enthalpies: kclo3: -391.4 kj/mol o2: 0 kj/mol kcl: -436.7 kj/mol

Asample of neon occupies a volume of 375 ml at stp. what will be the volume of neon if the pressure is reduced to 90.0 kpa? a. 422 ml b. 422 l c. 333 ml d. 333 l

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)

The independent variable in an experiment will be the variable that you o a) change ob) hold constant ng c) observe for changes
