Answer: valence electrons

Explanation:-

Chemical bond is formed either by sharing of electrons or transfer of valence electrons.

Chemical reactivity is defined as the tendency of an element to loose or gain electrons which are present in the last or valence shell which are called as valence electrons.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

$HF$ is formed by sharing of valence electrons of hydrogen and fluorine to complete their octet.

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.

Thus valence electrons participate in chemical bonding.

Why do you think the molarity relationship is so important to the chemist?

Oksana_A [137]

There are two big advantages of using molarity to express concentration. The first advantage is that it's easy and convenient to use because the solute may be measured in grams, converted into moles, and mixed with a volume.

The second advantage is that the sum of the molar concentrations is the total molar concentration. This permits calculations of density and ionic strength

Determina el numero de masa para el paladio en la siguiente tabla:*

Damm [24]

The concept of atomic masses we can find that the correct answer is:

c) 101

The atomic mass or mass number of an element is the sum of its protons plus the neutrons that are in the atomic nucleus, the electrons are not taken into account because they have a mass much lower than the masses of protons and neutrons.

In the table they indicate that there are 46 protons and 55 neutrons, therefore

M = #_ {protons} + #_ {neutrons}

M = 46 +55

M = 101

In conclusion using the concept of atomic masses we find that the correct answer is:

c) 101

When a skin diver is on the top of the water at 1.03 atm, her lung volume is 3.62L. How will the volume of her lungs change as s

Anon25 [30]

Answer:

–2.23 L

Explanation:

We'll begin by calculating the final volume. This can be obtained as follow:

Initial pressure (P₁) = 1.03 atm

Initial volume (V₁) = 3.62 L

Final pressure (P₂) = 2.68 atm

Final volume (V₂) =?

P₁V₁ = P₂V₂

1.03 × 3.62 = 2.68 × V₂

3.7286 = 2.68 × V₂

Divide both side by 2.68

V₂ = 3.7286 / 2.68

V₂ = 1.39 L

Finally, we shall determine the change in volume. This can be obtained as follow:

Initial volume (V₁) = 3.62 L

Final volume (V₂) = 1.39 L

Change in volume (ΔV) =?

ΔV = V₂ – V₁

ΔV = 1.39 – 3.62

ΔV = –2.23 L

Thus, the change in the volume of her lung is –2.23 L.

NOTE: The negative sign indicate that the volume of her lung reduced as she goes below the surface!
