Ascientist is performing an experiment in which he needs to increase the reaction rate of a solid. which of these actions will increase the reaction rate?

If two objects at different te,peraure are in contact with each other what happens to their temperature

Asubstance is a good conductor of electricity which of the following best explains a probable position of the substance in a periodic table

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)
