Consider the substances hydrogen (H2), fluorine (F2), and hydrogen fluoride (HF). Based on their molecular structures, how does
katovenus [111]

Answer:

The boiling point of HF is <u><em>higher than</em></u> the boiling point of H2, and it is <u><em>higher than</em></u> the boiling point of F2.

Explanation:

In HF, inter- molecule forces will be present between the hydrogen and fluorine atoms. There will be hydrogen bonding present among the hydrogen and fluorine atoms. Hydrogen bonds are strong bonds and hence the boiling point for HF would be high as much energy will be required to break these bonds.

H2 and F2 will only have intra-molecular attractions and there will be no hydrogen bonds present in them. As a result, their boiling point will be lower.

vivado [14]

Respuesta:

16,7 mL

Explicación:

Paso 1: Información provista

  • Concentración inicial (C₁): 6%
  • Volumen inicial (V₁): ?
  • 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

Helga [31]

Answer: The answer for this is Compound.

Explanation: A matter is something which occupies space and has some mass.

Elements are defined as the smallest substances which cannot be broken down into another substance by any chemical means.

A compound is a defined as a substance composed of two or more different elements when they combine chemically in definite proportion. For example: CO_2 is named as carbon dioxide and is a compound made by combining carbon and oxygen in a fixed ratio of 1 : 2

So, the answer to the given question is compound.
