11. Which best demonstrates an example of the common ion effect? A)A lighted splint goes out in air but bursts into flame when plunged l Into pure oxygen.

B)The compound Cucl is 500 times less soluble in sea water than it is in pure water.

C) Ammonla is produced commercially when an increase in pressure shifts the equilibrium toward the product.

D The decomposition of carbonic acid in water occurs spontaneously whereas the combination of carbon dloxide and water does not.

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

In what environment would mineral formation caused by high pressures and high temperatures most likely occur?

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
