In which of the following equilibrium systems will an increase in the volume cause the equilibrium to shift away from the reacta
Alenkinab [10]

Answer: 2NOBr(g) ⇌ 2NO(g) + Br2(g)

Explanation: For volume changes in equillibrium, the following are to be taken into consideration:

  • Volume changes have no effect on equillibrium system that contains solid or aqueous solutions.
  • An increase in volume of an equilibrium system will shift to favor the direction that produces more moles of gas.
  • A decrease in volume of an equilibrium system will shift to favor the direction that produces less moles of gas.
  • Volume changes will have no effect on the equillibrium system if there is an equal number of moles on both sides of the reaction.

2NOBr(g) ⇌ 2NO(g) + Br2(g) is the equillibrium system because there are more moles of products,therefore an increase in the volume of the reaction will shift to the right and produce more moles of products. Also both reactants and products exist in the gaseous state and does not have equal number of moles.

Calculates the equivalent mass of calcium chlorate CA (CI03) 2
love history [14]

Answer:

207g

Explanation:

Given compound:

            Ca(ClO₃)₂

The equivalent mass can be derived by summing the molar masses of each atom

  Molar mass of Ca = 40

                            Cl  = 35.5

                            O  = 16

Now solve;

 Molar mass  = 40 + 2(35.5 + 3(16)) = 207g
