Explain why oxygen is a fairly reactive element while neon is not

Chemistry
1 answer:
Blababa [14]3 years ago
8 0

Answer:

Due to presence of unpaired electrons in outermost shell of oxygen, oxygen is a fairly reactive element while neon is not.

Explanation:

Lets look at the electronic configuration of both the elements.

Oxygen, a chalcogen, has EC as =1s^{2}2s^{2}2p^{4}

while, for Neon, a noble gas, EC is = 1s^{2}2s^{2}2p^{6}

In neon, the outermost orbital p is completely filled while in oxygen it is partially filled, with 2 unpaired electrons.

<em>Thus the completely filled orbitals give extra stability to neon and thus less reactivity. In other case, oxygen has 2 unpaired electrons, unstable and has exchange energy, making it more reactive.</em>

Thus, oxygen is a fairly reactive element while neon is not..

Maya prepared 0.50 liters of a solution by dissolving 2.0 moles of an unknown compound in water. What is the molarity of the sol
Elena-2011 [213]

Answer:

4 M

Explanation:

Molarity can be represented by the following ratio:

Molarity = moles / volume (L)

Since you have been given both the mass and volume, you can plug the values into the equation and solve for molarity.

Molarity = moles / volumes

Molarity = 2.0 moles / 0.50 L

Molarity = 4 M

What is the mass of 2.9 moles of calcium? Explain please
Alik [6]

Answer:

116 g

Explanation:

From the question given above, the following data were obtained:

Number of mole of calcium = 2.9 moles

Mass of calcium =.?

The mole and mass of a substance are related according to the following formula:

Mole = mass / molar mass

With the above formula, we can obtain the mass of calcium. This can be obtained as follow:

Number of mole of calcium = 2.9 moles

Molar mass of calcium = 40 g/mol

Mass of calcium =.?

Mole = mass / molar mass

2.9 = mass of calcium / 40

Cross multiply

Mass of calcium = 2.9 × 40

Mass of calcium = 116 g

Therefore, the mass of 2.9 moles of calcium is 116 g.
