Umnica [9.8K]3 years ago
5 0

Answer:

\huge\blue{answer}

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.

What happens to the number of waves when you decrease the wavelength?
Keith_Richards [23]

C

Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.

Explanation:

The energy of a wave is given by the formula;

E= hf

Whereby;

E = energy

h = Plank’s constant

f = frequency

Remember that f can be also represented as;

¹/ λ

Whereby;

λ = wavelength

Wavelength and frequency are therefore inversely proportional.

Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.

In this experiment, 0.070 g of caffeine is dissolved in 4.0mL of water. The caffeine is extracted from the aqueous solution thre
Len [333]

Answer:

0.068 g

Explanation:

The equation that is used to determine the fraction q remaining in water of volume V₁ after n extractions of volume V₂ is:

qⁿ = (V₁/(V₁ + KV₂))ⁿ

Substituting in the values gives the fraction of caffeine left in the water phase:

q³ = (4.0mL/(4.0mL + 4.6(2.0mL))³ = 0.0278

The fraction of caffeine extracted into the methylene chloride phase is:

1 - 0.0278 = 0.972

The amount of caffeine extracted into the methylene chloride is:

(0.070g)(0.972) = 0.068 g
