The molar enthalpy of fusion for water is 6.008 kj/mol. what quantity of energy is released when 253 g of liquid water freezes?

84400 Joules

Explanation:

Molar enthalpy of fusion for water = 6.008 kJ/mol

Molar heat of fusion is the energy required to convert 1 mole of solid to 1 mole of liquid.

1 mole of liquid water on freezing releases energy = 6.008 kJ

Thus 14.06 moles of liquid water on freezing releases energy =

Thus 84400 Joules of energy is released when 253 g of liquid water freezes.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
