Consider 55 mL of water (H2O) in a beaker and 55 mL of acetone |(CHs)2CO in an identical beaker under identical conditions Compl
Zepler [3.9K]

Answer:

1. more slowly than

2. larger than

3. weaker

Explanation:

Acetone molecules are bonded by very weak intermolecular forces when compared to that of the hydrogen bond between water molecules. This makes it very easy for acetone molecules to vaporize easily into its gaseous state, much more faster than water molecules (since the acetone molecules need a lesser amount of energy to break these bonds). Also, the boiling point of liquid acetone is much lower than that of water, meaning that it has a higher vapor pressure than that of water.

How does the chemical formula for water influence its chemical properties?
OLga [1]

The chemical formula is composed of hydrogen and oxygen where the two atoms are bonded through hydrogen bond type of bonding. In this pair, the oxygen is the more electronegative atom hence the electrons are more directed to it. Because of this, this creates electron polarity which affects the chemical property of water.

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment. how many quarts (qt) are in 2.50 l? (1 l =1.06 q
trasher [3.6K]

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.

<h3>What is conversion factor?</h3>

Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.

Given that quantity of salt solution = 2.50 L

We know that, 1 L = 1.06 qt

Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:

2.50L = 2.50L × 1.06qt/L = 2.65qt

Hence required value is 2.65qt.
