Why is a saturated nacl solution an example of an equilibrium system?

How have the greenhouse gasses increased from the year 2000 to 2018

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

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)
