Si tomas 100ml de una solución de Nacl 4m y se disuelve en 200ml utilizando el mismo solvente ¿cuál será la nueva concentración?

Answers

Answer 1
Answer:

Respuesta:

2 m

Explicación:

Paso 1: Información provista

  • Volumen inicial (V₁): 100 mL
  • Concentración inicial (C₁): 4 m
  • Volumen final (V₂): 200 mL
  • Concentración final (C₂): ?

Paso 2: Calcular la concentración de la solución final

Queremos perparar una concentración diluida a partir de una concentrada. Podemos calcular la concentración de la solución diluida usando la regla de dilución.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 4 m × 100 mL / 200 mL = 2 m

In what respect does an atom of magnesium differ from a magnesium ion (Mg^{2+})? a. The ion has a more stable electronic arrangement than the atom.
b. The positive charge on the nucleus of the ion is two units greater than the nuclear charge on the atom.
c. The ion has two more protons than the atom.
d. The ion will react more readily with free Cl₂. (E)The ion has two more planetary electrons than the atom. Can anyone explain this one?

Answers

The correct answer is A.  Atoms and ions only differ in the number of electrons each one has and atoms form ions to achieve a more stable electron configuration.

A 133.8-gram sample of bronze was 10.3% tin by mass. Determine the total mass of tin in the sample.

Answers

You just need to multiply the total mass by the decimal value of the part that is tin. 133.8*0.103=13.8g (following the rules of significant figures).

How does vegetation slow and prevent sediment loss?

Answers

Vegetation cover is the most effective and practical way to prevent loss of sediment. The roots of vegetation such as grass bind soil particles together to resist erosion especially from runoff water. Vegetation helps absorb the impact of raindrops to prevent detachment of soil particles. Vegetation can flatten act like shingles on a roof, which allows the runoff to flow above the soil.Stiff standing vegetation act as a wind break, reducing wind velocity, such that it is not powerful enough to dislodge sediments from the ground surface.

Final answer:

Vegetation slows and prevents sediment loss in rivers and streams by binding the soil together and slowing down the flow of water. Shade from plants also helps reduce phytoplankton growth.

Explanation:

Vegetation plays a crucial role in slowing and preventing sediment loss in rivers and streams. The roots of plants help bind the soil together, reducing erosion caused by the force of water. As water flows through vegetation, it is slowed down, allowing sediment to settle out. Additionally, plants provide shade, which helps keep the water temperature lower, creating an environment less suitable for phytoplankton growth.
