Answer: The correct answer is Option B.

Explanation:

A covalent bond is formed when sharing of electrons takes place between the atoms combining. The atom which attracts the shared pair of electron towards itself is more electronegative and the atom which does not attracts the shared pair of electron towards itself is less electronegative.

In HCl molecule, more electronegative atom is chlorine atom having an electronegativity of 3.16 and hydrogen has an electronegativity of 2.1

So, majority of shared electrons will be found near to the chlorine atom in hydrochloric molecule.

Hence, the correct answer is Option B.

What is the difference between heterozygous and homozygous?

Yuri [45]

we can differentiate a heterozygous individual from a homozygote by analyzing their alleles. If the alleles in the homologous chromosomes are the same, we say that it is a homozygote. If the alleles are different, the individual is heterozygous.

Explain how you would decide which represents a greater mass: 3.25 x 1022 atoms of Ca or 2.45 grams of Mg?

elena55 [62]

Answer:

You need to convert the number of atoms of Ca into mass in grams, using Avogadro's number and the atomic mass of Ca.

Explanation:

The amount of matter is measured in grams. Thus, you need to convert the number of atoms of Ca (calcium) into mass to compare with 2.45 grams of Mg.

To convert the atoms of calcium into mass, you divide by Avogadro's number, to obtain the number of moles of atoms, and then divide by the atomic mass of calcium.

1. Number of moles, n

$n=\dfrac{\text{number of atoms}}{\text{Avogadro's number}}\\ \\ \\ n=\dfrac{3.25\times 10^{22}}{6.022\times 10^{23}}=0.053969mol$

2. Mass

mass = number of moles × atomic mass

mass = 0.053969mol × 40.078g/mol = 2.16g

Then, 2.45 g of Mg represent a greaer mass than the 3.25 × 10²² atoms of Ca.
