How many electrons are there in the valence shell of the oxygen atom of water? O a. 2 O 6.4 OC.6 O d. 8

Chemistry

denpristay [2]3 years ago

7 0

Answer:

d. 8

Explanation:

Valence electrons of oxygen = 6

Valence electrons of hydrogen = 1

The total number of the valence electrons = 6 + 2(1) = 8

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete.

In the water molecule,

Oxygen has 2 bond pairs and two lone pairs which means that the total electrons in the valence shell is 8.

Josefina and Raul were comparing how sound moves through various mediums and how charge moves through conducting wires. They per

Fed [463]

They found that difference occurs in the speed of both sound and charges occur due to the difference in the type of medium.

Sound and charges needs specific medium for faster movement i.e. sound moves faster in solid as compared to liquid and gas whereas charges moves faster and easily in gold due to lower resistance which is followed by copper. Sound can move from solid, liquid and gases whereas charges move only in solid metal in which free electrons are present. The speed of sound and flow of current are affected due to difference in the arrangement of atoms in solid, liquid and gas.

Given the reactant side of the total ionic equation for the neutralization reaction of ammonium hydroxide (NH4OH) with hydrochlo

natita [175]

Answer:

NH₄⁺ (aq) + OH⁻ (aq)+ H⁺ (aq)+ Cl⁻ (aq) → NH₄⁺ (aq)+ Cl⁻ (aq)+ H₂O (l)

Explanation:

NH₄OH (l) + HCl (l) → NH₄Cl (aq) + H₂O (l)

This is called a molecular equation because the formulas of the compounds are written as though all species existed as molecules or whole units.

However, because both the acid and the base are strong electrolytes, they are completely ionized in solution. Therefore, the ionic equation is:

NH₄⁺ (aq) + OH⁻ (aq)+ H⁺ (aq)+ Cl⁻ (aq) → NH₄⁺ (aq)+ Cl⁻ (aq)+ H₂O (l)

What do you notice about the distance between the terrestrial planets compared with the spacing between the gas giants

LekaFEV [45]

Answer:

The spacing between the terrestrial planets is less than that between the gas planets.

Explanation:

Since the terrestrial planets which are Mercury, Venus, Earth and Mars have a distance of 0.4 AU, 0.7 A.U, 1.0 AU and 1.5 A.U respectively from while the gas planets which are Jupiter, Saturn, Uranus and Neptune have a distance of 5.2 AU, 9.6 AU, 19.6 AU and 30 AU respectively from the sun, we can see that the spacing between the terrestrial planets is much smaller than the spacing between the gas planets.

For example, the spacing between Mercury and Venus is 0.7 AU - 0.4 AU = 0.3 AU while that between Earth and Venus is 1.0 AU - 0.7 AU = 0.3 AU.

Also, the spacing between Earth and Mars is 1.5 AU - 1.0 AU = 0.5 AU.

Also too, the spacing between the gas planets is shown below the spacing between Jupiter and Saturn is 9.6 AU - 5.2 AU = 4.4 AU while that between Uranus and Saturn is 19.6 AU - 9.6 AU = 10.0 AU.

Also, the spacing between Neptune and Uranus is 30 AU - 19.6 AU = 10.4 AU.

Thus, we can see that the spacing between the terrestrial planets is less than that between the gas planets.

Note that AU means astronomical unit and 1 AU is the distance between the Earth and the Sun. 1 AU = 1.50 × 10⁸ km

What do we call the lines around the nucleus of an atom?

nasty-shy [4]

Explanation:

As you know, electrons are always moving. They spin very quickly around the nucleus of an atom. As the electrons zip around, they can move in any direction, as long as they stay in their shell. Any direction you can imagine — upwards, downwards, or sidewards — electrons can do it. Electrons are constantly spinning in those atomic shells and those shells, or orbitals, are specific distances from the nucleus. If you are an electron in the first shell, you are always closer to the nucleus than the electrons in the second shell.
