Answer:
Concentration will decrease
Explanation:
The question is incomplete, the question is;
Which drawing best accounts for the polarity of methanol, CH3OH, and the bond polarities that make a major contribution to the overall molecular polarity?
A) drawing (1) B) drawing (2)
D) drawing (4) C) drawing (3)
Answer:
B) drawing (2)
Explanation:
In Chemistry, the direction of dipole is shown from positive end to negative end.
The image that contains the options in the question asked has been attached.
We can see in image 2 that the oxygen atom was correctly designated as the negative end of the dipole while the carbon and hydrogen atoms were each designated as positive ends of the dipole in accordance with the magnitude of electronegativity difference between the two atoms. The net dipole moment is now taken in the direction shown in image 2. This is the correct answer.
The tshirt that is going to absorb most amount of sunlight is the black t-shirt. This is because its reflectivity is almost zero that it is not capable of reflecting back the light to the surface. This is the very reason why we are feeling so warm when we wear a black t-shirt.
(1) O2 Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(2) Xe Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(3) C3H8 Is a Nonelectrolyte: because it does not ionize when dissolved in a solution
(4) KNO3 Is an electrolyte: because it ionizes when dissolved in a solution
Electrolytes:
Electrolytes are the substance whose aqueous solution conducts electricity. These are mainly two types:
1. Strong electrolytes
2. Weak electrolytes:
Strong electrolytes:
Strong electrolytes have following properties:
1. They are ionic compounds.
2. They are completely separates into their ions when dissolved in water.
3. In solution form they conduct electricity due to present of ions but in solid form means neutral molecule does not conduct electricity.
Weak electrolytes:
Weak electrolytes are partially ionizes in water.
In general strong electrolytes are strong acid and strong base while weak electrolytes are weak acid and weak bases.
Nonelectrolyte:
The substance which does not ionize when dissolved in a solution is called non-electrolyte. It is a poor conductor of electricity.
