Glist the substances nacl, cl2, ch3cl, and ch3cooh in order of increasing strength of intermolecular attractions.

Explanation:

NaCl is an ionic compound as bond between sodium and chlorine is formed by transfer of electrons.

Bonding in molecule is covalent as it is formed by sharing of electrons. Thus, in molecule both the chlorine atoms are held together by weak Vanderwaal forces.

In , there will be dipole-dipole interaction between the molecules due to difference in electronegativity between and Cl atom.

In , there will be dipole-dipole interaction and hydrogen bonding between the atoms.

Thus, we can conclude that increasing strength of intermolecular attractions will be as follows.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
