A diatomic molecule shares three pairs of electrons. What type of bond is present in the molecule? A single covalent bond becaus
VMariaS [17]
<h3><u>Answer</u>;</h3>

A triple covalent bond because each atom requires three more electrons to complete its octet.

<h3><u>Explanation</u>;</h3>
  • A triple covalent bond is a covalent bond formed by atoms that share three pairs of electrons.
  • For example;<em><u> in a diatomic molecule such a nitrogen; A nitrogen atom has five valence electrons, which can be shown as one pair and three single electrons. </u></em>When combining with another nitrogen atom to form a diatomic molecule, the three single electrons on each atom combine to form three shared pairs of electrons.

Why might two elements posses similar chemical properties?​
Tems11 [23]

Same number of valence electrons

Explanation:

Two elements posses similar chemical properties if they have the same number of valence electrons.

Chemical properties of any substance is determined by the number of valence electrons it possesses in its outer most shell.

Elements use their valence electrons to form chemical bonds with one another.

Elements with the same number of valence electrons will chemically combine the same way.

This is why elements in the same group on the periodic table have the same chemical properties.

What is the volume of 6.40 grams of O₂ gas at STP?
gtnhenbr [62]

The volume of 6.40 grams of O₂ gas at STP is 4.48L (option A). Details about volume can be found below.

<h3>How to calculate volume?</h3>

The volume of a gas can be calculated using the following formula:

p = m/v

Where;

  • p = density
  • m = mass
  • v = volume

According to this question, the mass of O₂ gas at STP is 6.40 grams. The density of the gas at STP is 1.43 g/L.

1.43g/L = 6.4g/V

Volume of O2 = 6.4 ÷ 1.43 = 4.48L

Therefore, the volume of 6.40 grams of O₂ gas at STP is 4.48L.
