For the 2nd IE of Na an electron is being removed from the 2p subshell.For the 2nd IE of Mg an electron is being removed from the 3s subshell.It requires more energy to remove an electron from a lower ene...

first, write down the mass, Mr and calculate the moles of NaCl.mass = 350gMr = 24.0 + 35.5 = 58.5mol = mass/Mr = 350/58.5 = 5.98 (3s.f)now calculate the concentration in 3dm3 of watervol = 3mol = 5.98conc...

By definition, ΔH°_rxn = Σ ΔH°_f (products) − Σ ΔH°_f (reactants).The enthalpy of combustion is the same as the enthalpy of reaction in this case. From Table 10, we can get t...

Chlorine's outer electrons are closer to the nucleus than iodine, so greater attraction from the positive nucleus making it easier to gain an electron.
