Answer:
The correct answer is the first option
Explanation: hope this helped
1. Resonance structures are a better description of a Lewis dot structure .
2. Best resonance structure is the one with the least formal charge.
<u>EXPLAINATION OF RASONANCE STRUCTURE OF CARBON DIOXIDE</u>
1.Carbon dioxide has three resonance structures .
2. The CO2 molecule has a total of 16 valence electrons ,
1C = 4 electrons
2O= 12 electrons
<u>three resonance structures for CO2</u>
1. The atoms in all three resonance structures have full octets;
structure 1 will be more stable because it has no separation of charge.
2. Structures 2 and 3 show charge separation caused by the presence of formal charges on both oxygen atoms.

Explanation:
At the beginning, you have two reactions happening:

As you add KOH(aq), it does two things:
- It increases the volume of the solution.
- It reacts with the hydronium ions to form water.
A) The HCl is completely ionized. The Cl⁻ does not react, but it is diluted when the volume of the solution increases. [Cl⁻] decreases.
B) The KOH reacts with the H⁺ and removes it from the solution. [H⁺] decreases.
C) When all the H⁺ from the HCl has been neutralized, the KOH starts neutralizing the H⁺ from the HClO₂. According to Le Châtelier's Principle, more HClO₂ will dissociate to replace the decreased H⁺. [HClO₂] decreases.
D) As HClO₂ reacts, it forms ClO₂⁻. ![\boxed{\rm \textbf{[ClO$_{2}^{-}$] increases}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Crm%20%5Ctextbf%7B%5BClO%24_%7B2%7D%5E%7B-%7D%24%5D%20increases%7D%7D)

Answer:
2.40 × 10²³ Atoms of Hydrogen
Solution:
The number of hydrogen atoms in C₃H₈O₃ are calculated as;
As, there are eight hydrogen atoms per molecule of C₃H₈O₃, therefore the number of hydrogen atoms per mole of C₃H₈O₃ are calculated as;
1 mole C₃H₈O₃ contains = 6.022 × 10²³ Molecules of C₃H₈O₃
So,
0.05 mole C₃H₈O₃ will contain = X Molecules of C₃H₈O₃
Solving for X,
X = (0.05 × 6.022 × 10²³) ÷ 1
X = 3.011 × 10²² Molecules of C₃H₈O₃
As,
1 Molecule of C₃H₈O₃ contains = 8 Atoms of Hydrogen
So,
3.011 × 10²² Molecules of C₃H₈O₃ will contain = X Atoms of Hydrogen
Solving for X,
X = (3.011 × 10²² × 8) ÷ 1
X = 2.40 × 10²³ Atoms of Hydrogen
