Intermolecular forces are forces of interaction that are operative between two different molecules. They are of follow types
1) Dipole- dipole interaction
2) Hydrogen bonds
3) vander Waal's forces
Depending upon the polarity and constitution molecule above forces are operable.
for instance, in case of ammonia, Hydrogen bonds exist because hydrogen atom is attached to electronegative element i.e. N
HCl and CO are polar molecules, so dipole-dipole interaction is operative in these molecules.
Finally in case of CO2, vander Waal's forces of interaction is operable because it is a non-polar molecule.
Explanation:
tThe Hubble constant, H0, is approximately 73 km/(s × Mpc). This value is given in mixed units because it uses both kilometers and megaparsecs, which both measure distance. Multiplying this value by the conversion factor (1 Mpc)/(3.086 × 1019 km) fixes this issue. What is the resulting value for the Hubble constant? Write your answer in scientific notation. Be sure to include simplified units.
The best answer for the question above would be the chloroflourocarbons or the CFCs. These chloroflourocarbons or CFCs are the ones responsible for the depletion of the ozone - which leads to leaving a hole in its layer. These gases eat out the ozone layer and allows harmful UV rays of the sun to come in the Earth.

Answer:
3.16g of the ester are produced
Explanation:
First, we need to determine the limiting reactant of the reaction converting each reactant to moles:
<em>Moles CH3COOH (Molar mass: 60g/mol):</em>
3.58g * (1mol / 60g) = 0.05967moles
<em>Moles C5H11OH (Molar mass: 88.15g/mol):</em>
4.75g * (1mol / 88.15g) = 0.05389 moles
As the reaction is 1:1, limiting reactant is C5H11OH.
Theoretical moles of the ester CH3COOC5H11 is 0.05389 moles.
As only the 45.00% is produced:
0.05389 moles * 45.00% =
0.02425 moles of CH3COOC5H11 are produced.
In mass (Molar mass CH3COOC5H11: 130.1849g/mol):
0.02425 moles * (130.1849g / mol) =
<h3>3.16g of the ester are produced</h3>
