Study the reaction. 2HCl (g)+I2 (s)⇌2HI (g)+Cl2 (g)
When the reaction is at equilibrium, some amount of HI is added. The system then reaches equilibrium again.

How does the concentration of Cl2 change compared to the first equilibrium?

The concentration is zero.
The concentration is zero.

The concentration is lower.

The concentration is the same.

The concentration is higher.

How can carbon move from "land" to bodies of water? describe the way human impact has lead to increased levels of co2 in the atmosphere.

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 polarity of an oxygen-hydrogen bond is higher than the polarity of a nitrogen-hydrogen bond, allowing amines to be more soluble than alcohols.
