Question The molar mass of I, is 2543 and that of astatine (Aty) is 420 $ Which one has the higher melting point and why? mol mo Select the correct answer below: O 12, because it has lower molar mass and therefore the dispersion forces between molecules are smaller. O 1, because it has the greater molar mass and therefore the dispersion forces between molecules are stronger O At, because it has greater molar mass and therefore stronger dispersion forces O Aty, because it has lower molar mass and therefore stronger dispersion forces FEEDBACK MORE INSTRUCTION SUBMIT Question What is the difference between polar covalent bonds and nonpolar covalent bonds? Select the correct answer below: O polar covalent bonds: unequal distribution of protons nonpolar covalent bonds: equal distribution of protons O polar covalent bonds: equal distribution of protons nonpolar covalent bonds: unequal distribution of protons O polar covalent bonds: unequal distribution of electrons nonpolar covalent bonds: equal distribution of electrons O O polar covalent bonds: equal distribution of electrons nonpolar covalent bonds: unequal distribution of electrons E FEEDBACK MORE
