Which type of intermolecular or interatomic force does methylated spirits fall under?​
Triss [41]

Of all the substances used, water possesses the strongest intermolecular forces (hydrogen bonds). Although hydrogen bonds exist in glycerin and methylated spirits as well, they are a little weaker than in water.

Intermolecular forces in ch3oh include London dispersion forces, dipole dipole attraction, and hydrogen bonding. Methylated spirits, a common industrial solvent, are mostly made of ethyl alcohol. Because methanol denatures ethyl alcohol, commercial supply is exempt from the typical taxes and charges imposed on alcohol. A quantity of methyl alcohol or phenol is added to make it so that drinking it will make you go blind. Alcohols have the hydrogen bonding and van der Waals intermolecular forces of attraction.

You have 150. g of a bleach solution. The percent by mass of the solute, sodium hypochlorite (NaOCI), is 3.62%.
Taya2010 [7]

Answer:

There are 5.43 grams of NaOCl

Explanation:

The given percent by mass of the solute tells us that out of the 150 g of the solution, 3.62% are due solely to the solute.

In other words, <u>the mass of the solute in the solution is</u>:

  • 150 g * 3.62/100 = 5.43 g

Thus, in 150 grams of the given bleach solution, there are 5.43 grams of sodium hypochlorite.
