Why is water (H2O) considered the "universal solvent"?

Answers

Answer 1

Answer: It is considered as a universal solvent since most substances dissolve in water. And comparing it to other liquids, it is the one who dissolves a wide range of substances. Also, it is an important substance for every living thing.

If gas particles start colliding with the walls of their metallic container with increase force what is their direct effect

Answers

Answer: The increase in force will directly effect the pressure exerted by the gas that is high pressure of the gas.

Explanation:

The pressure is defined as force applied per unit area.

$Pressure=(Force)/(Area)$

$Pressure\propto Force$

If the gas particles colliding with the walls of container with increase in force then the pressure of the gas exerted by the particles of the gas will also get increased.

I believe your answer would be higher gas pressure.

39 Which formula represents a molecule with the most polar bond?(1) CO (3) HI
(2) NO (4) HCl

Answers

Answer: (1) CO

Explanation: A molecule is said to be polar when it has atoms with different electronegativities. The more is the difference in electronegativity, the more polar is the bond.

Electronegativity of carbon and oxygen are 2.5 and 3.5 respectively. Thus difference is (3.5-2.5)=1.0.

Electronegativity of hydrogen and Iodine are 2.1 and 2.7 respectively. Thus difference is (2.7-2.1)=0.6.

Electronegativity of nitrogen and oxygen are 3.0 and 3.5 respectively. Thus difference is (3.5-3.0)=0.5.

Electronegativity of hydrogen and chlorine are 2.1 and 3.0 respectively. Thus difference is (3.0-2.1)=0.9.

Thus as the highest difference of electronegativity is among carbon and oxygen, CO is the most polar.

Which formula represents a molecule with the most polar bond? (1) CO (3) HI (2) NO (4) HCl

The formula that represents a molecule with the most polar bond is the HCl, hydrochloric acid. The answer is number 4.
