9. Which of the following statement is incorrect? (A) Across a period from Sc to Cu, the densities increase with
increasing atomic number
(B) The noble character of transitions metals is due to high
ionization energies, high enthalpies of solvation and higher
thalpies of sublimation
(C) on going down a group from 3d to 6d series, the stability
of higher oxidation state increases with stability of high
oxidation state increases with increasing atomic numbers

8 carbon atoms forming single bonds with 18 hydrogen atoms; a triple bond exists between the third and fourth carbon atom from the right

explanation:

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).
