Respuesta:
16,7 mL
Explicación:
Paso 1: Información provista
- Concentración inicial (C₁): 6%
- Concentración final (C₂): 0,5%
- Volumen final (V₂): 200 mL
Paso 2: Calcular el volumen de la solución concentrada
Queremos preparar una solución diluida de hipoclorito de sodio a partir de una concentrada. Podemos calcular el volumen inicial que debemos tomar usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 0,5% × 200 mL / 6% = 16,7 mL
The characteristic of reactions that depends on valence electrons is the bond type.
In chemistry, a chemical bond could be;
The type of bond formed depends on the number of valence electrons present. When there are few valence electrons on an atom, it mostly forms ionic bonds.
When there are more electrons on an atoms, it mostly forms covalent bonds and the electrons between the atoms are shared.

CH3COOH has the highest boiling point because it has hydrogen bonds.
<h3>
What is the boiling point?</h3>
- The boiling point of a substance is the temperature at which a liquid's vapor pressure equals the pressure surrounding the liquid and the liquid turns into vapor.
- The boiling point of a liquid varies with the surrounding atmospheric pressure.
- The normal boiling point of a liquid (also known as the atmospheric boiling point or the atmospheric pressure boiling point) is the special case in which the liquid's vapor pressure equals the defined atmospheric pressure at sea level, one atmosphere.
To find which substance has the higher boiling point, CH₃OOH or CH₃CH₃:
- Because of the hydrogen bonds, CH₃OOH has the highest boiling point.
- Because of the strongest intermolecular forces, it has the highest boiling point.
Therefore, CH3COOH has the highest boiling point because it has hydrogen bonds.
