Hello!
To solve this question, we need to use the
Avogadro's Number, which is a constant first discovered by
Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are
6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:
So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent
14,12 moles of Na₂SO₃
Have a nice day!
The volume of Hydrogen gas : 24 L
<h3>Further explanation</h3>
Given
16 L Ammonia(NH₃)
Required
The volume of Hydrogen gas
Solution
Reaction
N₂ + 3H₂ ⇒ 2NH₃
Avogadro's hypothesis:
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so volume of H₂ :
= 3/2 x volume of NH₃
= 3/2 x 16 L
= 24 L
Yes, it's important that acids and bases have different properties. Because they'll react differently.
Answer:
B. Nonpolar covalent bond
Explanation:
Between two Nitrogen atoms, a non-polar covalent bond would be formed.
So, what is the nature of a covalent bond, and what makes a covalent bond non-polar?
A covalent bond is a type of bond that forms between two atoms that shares their valence electrons. The valence electrons are donated by the two atoms and they are shared in order to achieve an octet. This bond type is predominantly between atoms that have an electronegativity difference less than 0.5. Using the electronegativity values, we see that a difference of 0 would be obtained.
Due to equal affinities of the two atoms for the valence electrons, none of them will pull the electrons closer to themselves. There won't be any form of charge separation on the two atoms and a Nitrogen molecule will form. This makes the bond type a non-polar covalent type.
