Why does hydrogen have a -1 oxidation state in the compound NaH? a-H has no electronegativity value
b-Na has a lower electronegativity than H
c-Na has higher electronegativity than H
d-Na and H have the same electronegativity values

Less stable  hope this

The correct answer would be b) volume versus temperature, because they are also directly proportional.

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
