The boiling point of H2O is much higher than that of the analogous molecule H2S. This is mostly due to Group of answer choices dispersion forces being much stronger in H2S than in H2O. dipole-dipole forces being much stronger in H2S than in H2O. hydrogen bonding being much stronger in H2O than in H2S. dipole-dipole forces being much stronger in H2O than in H2S. hydrogen bonding being much stronger in H2S than in H2O.

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom. 

Isec i will do it and them i will let you know

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
