Below is the Lewis structure of the hydrogen cyanide molecule.

Chemistry
1 answer:
lianna [129]3 years ago
8 0

Answer :

The number of bonding pairs of electrons around the hydrogen atom = 2

The number of lone pairs of electrons around the hydrogen atom = 0

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, HCN

As we know that carbon has '4' valence electrons, hydrogen has '1' valence electrons and nitrogen has '5' valence electrons.

Therefore, the total number of valence electrons in HCN = 1 + 4 + 5 = 10

According to Lewis-dot structure we conclude that, there are 8 number of bonding electrons and 2 number of non-bonding electrons.

The number of bonding pairs of electrons around the hydrogen atom = 2

The number of lone pairs of electrons around the hydrogen atom = 0

Which is a genotype?
Pani-rosa [81]

Answer:

Genotypes are related with the collection of genes expressed in the DNA.

Explanation:

Hello,

In genetics, two specific terms define the characteristics of a living thing; a genotype and a phenotype; thus, phenotypes are related with the physical manifestation of genes, for instance, red hair, blue eyes, long arms and others.

On the other hand, genotypes are related with the collection of genes expressed in the DNA, and they could be for equal alleles or for different alleles, in other words, it is the version of DNA the living thing has.

Regards.

What does the root word “atom” mean and why is that not an accurate name
Maksim231197 [3]

Answer:

Explanation:

The concept of the atom originated round 440 BC. Leucippus of Miletus came up with the idea. ... Atoms were impenetrably hard, meaning they could not be divided. In Greek, the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos, a Greek word meaning uncuttable.

28. What is the heat of reaction for the forward reaction?
ValentinkaMS [17]

Answer:

Check Explanation

Explanation:

The Heat of reaction for the forward reaction is defined as the amount of heat given off or absorbed while the forward reaction is taking place. Mathematically, the heat of reaction for the forward reaction is given as the heat content/heat of formation/Enthalpies of the reaction's products minus the heat content/heat of formation/Enthalpies of the reaction's reactants.

ΔH°run = H°(products) - H°(reactants)

When the heat of reaction is negative, the reaction is said to be exothermic and when it is positive, the reaction is said to be endothermic.
