Determine whether the following statements are true or false. Correct the false statements. The concentrations of the products are equal to the concentrations of the reactants at equilibrium.  The rates of the forward and reverse reactions are the same at equilibrium.

Solid carbon dioxide is also called dry ice. Dry ice is placed in a sealed container. Some CO2 sublimes and the following equilibrium is formed: CO2 (s) = CO2 (g) If the amount of solid CO2 (dry ice) in the container is doubled what would happen? (Hint: Write the equilibrium constant expression.)   Solid carbon dioxide is also called dry ice. Dry ice is placed in a sealed container. Some CO2 sublimes and the following equilibrium is formed: CO2 (s) = CO2 (g) If the amount of solid CO2 (dry ice) in the container is doubled what would happen? (Hint: Write the equilibrium constant expression.)   The amount of CO2 (g) would increase, but not double.  The amount of CO2 (g) would double. The partial pressure of CO2 (g) would increase.  The amount of CO2 (g) would not change.

Can you help me every step by step with number 3 part A,  part B, part C, part D? Can you explain it to me?

For each reaction in the table below, write the chemical formulae of any reactants that will be oxidized in the second column of the table. Write the chemical formulae of any reactants that will be reduced in the third column. reactants reactants reaction oxidized reduced 2Cu(s) + I, (s) → 2CuI (s) 0, (8) + Cr(s) → Cro, (s) 8Ca (s) + S, (s) → 8CAS (s)
