Answer: Option (B) is the correct answer.

Explanation:

Good conductors are defined as the substance through which heat can effectively pass.

For example, copper, and iron are good conductors of heat and electricity.

Generally, metals are good conductors of heat as well as electricity.

On the other hand, bad conductors are the substances through which heat is unable to flow.

For example, glass, wood, foam etc are all bad conductors of heat as well as electricity.

Thus, we can conclude that out of the given options copper and iron are good conductors of heat.

Answer: Option (B) is the correct answer.

Explanation:

Metals are the substances that have more number of electrons. Metals are good conductors of heat and electricity.

For example, iron, copper, zinc are all metals and good conductors of heat and electricity.

Whereas wood and foam are is a poor conductor of heat and electricity.

Thus, we can conclude that out of the given options copper and iron are good conductors of heat.

Due to the small and highly electronegative nature of fluorine, the oxyacids of the this element are much less common and less s

Molodets [167]

Answer:

HOFO = (0, 0, +1, -1)

Explanation:

The formal charge (FC) can be calculated using the following equation:

$FC = V - N - \frac{1}{2}B$

<u>Where:</u>

V: are the valence electrons

N: are the nonbonding electrons

B: are the bonding electrons

The arrange of the atoms in the oxyacid is:

H - O₁ - F - O₂

Hence, the formal charge (FC) on each of the atoms is:

H: FC = 1 - 0 - 1/2*(2) = 0

O₁: FC = 6 - 4 - 1/2*(4) = 0

F: FC = 7 - 4 - 1/2*(4) = +1

O₂: FC = 6 - 6 - 1/2*(2) = -1

We can see that the negative charge is in the oxygen instead of the most electronegative element, which is the F. This oxyacid is atypical.

I hope it helps you!

Which pair will for an ionic compound

vovikov84 [41]

Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.

Explanation:

A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.

Explanation:

The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.
