The conductance of the electric current through the electrolytic solution increases with
zheka24 [161]

The conductance of the electric current through the electrolytic solution increases with increase in concentration.

<h3>What is electrolytic solution?</h3>

Electrolytic solutions are solutions that are capable of conducting an electric current due to presence of ions.

The current flowing in an Electrolytic solutions is calculated as;

Q = It

I = Q/t

where;

  • Q is charges

Increase in the concentration of the charges, increases the amount of charges in the solution and hence the conductance of the solutions will increase as well.

Which of the following compounds is a gas at room temperature? A : CH3CH2OH B : CH3CH2CH2CH2CH2CH2CH3 C : CH3CH2CH3 D : HOCH2CH2
attashe74 [19]

Answer:

C. CH_3CH_2CH_3

Explanation:

Molecules with the stronger intermolecular forces are pulled tightly together  to form solid at higher temperatures and that's why the freezing point is higher.

Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.

Thus, melting point and boiling point increases with increase in number of carbon atoms and also increase in intermolecular forces (like hydrogen bonding, if present).

Thus, the compound which is gas at room temperature is CH_3CH_2CH_3 <u>because it has least number of carbon atoms and absence of hydrogen bonding.</u>

Why are halogens reactive?
erica [24]

<u>Halogens are reactive because:</u>

They have high electronegativity and also high nuclear charge. So, they are reactive and also gain an electron when they react with other elements.

Since they are very reactive, halogens are very harmful to living organisms. Some of the halogens are fluorine, chlorine, bromine, iodine, astatine. These are mostly non metals. Fluorine is one of the most reactive gas and also very toxic gas. When Fluorine reacts with glass along with small amounts of water, it forms silicon tetra fluoride (SiF4). Hence fluorine should be handled with substances like the inert organofluorine compound Teflon.
