Answer:
When factories mass produce something it produces smoke. That smoke can be harmful to something called the ozone layer. The ozone layer is part of earth's atmosphere that protects us from the suns burning heat. When that layer is damaged the sun's heat burns through heating up the world and melting ice causing the water levels to rise. All of this can make working conditions less safe, cause more flooding, and have the sun cause cancer.
Answer:
The difference in the electronegativities of chlorine and boron is 3.0 - 2.0 = 1.0 ; the difference in between chlorine and carbon is 3.0 = 2.5 = 0.5 . Consequently, the B-Cl bond is more polar ; the chlorine atom asrries the partial negative charge because it has higher electronegativity .

Answer:
66.67%
Explanation:
From the given information:
mass of cyclohexane = 2.9949 grams
density of cyclohexane = 0.779 g/mL
Recall that:
Density = mass/volume
∴
Volume = mass/density
So, the volume of cyclohexane = 2.9949 g/ 0.779 g/mL
= 3.8445 mL
Also,
mass of propylbenzene = 1.6575 grams
density of propylbenzene = 0.862 g/mL
Volume of propylbenzene = 1.6575 g/ 0.862 g/mL
= 1.9229 mL
The volume % composition of cyclohexane from the mixture is:



= 66.67%
C ?
each sex cell has 23 unpaired cells, a regular cell would have 46.
The empirical formula of the given compound is
.
The correct option is B.
<h3>What is an empirical formula?</h3>
The empirical formula of a chemical compound is the simplest whole-number ratio of atoms contained in the substance.
Given,
1.0 g of S
1.5 g of O
To calculate the empirical formula, we will divide the masses of the elements by their atomic weight.
For sulfur

For oxygen

Now, divide the greater value of mole came by the smaller value

Thus, the empirical formula for the given compound is 1 for S and 3 for O
