The correct answer to your question is

C. Buried underground

Radioactive waste is being buried underground because we have no where else to put it, and it must be away from us because it is harmful.

How can you tell if both crops of crystals are your product? Why would additional solid precipitate in your filtrate?

Leto [7]

Crops of the crystals are a part of the same crystal which might have different chemical structures leading to different colors.

<u>Explanation:</u>

Crops of the crystals are the parts of the crystals. And even being a part of the same crystal, the crops of the crystals can have different colors from the other crops of the crystal.

The color of crops of crystals are dictated by the chemical structure and their physical characteristic (crystalline or formless). The shape and the size of its crystalline structure, likewise the chance of polymorphism, may impact its shading.

What is the frequency of a wave with a wavelength of 6.40 x 104 meters??

Zina [86]

Answer:- $4.69*10^3Hz$

Solution:- Wavelength is given and we are asked to calculate the frequency. The equation that correlates frequency with wavelength is:

$\nu =\frac{c}{\lambda }$

where, $\nu$ is the symbol for frequency, c is the symbol for speed of light and $\lambda$ is the symbol for wavelength.

Speed of light is $3.0*10^8\frac{m}{s}$ and the wavelength is given as $6.40*10^4m$ .

Let's plug in the values in the equation and so the calculations to calculate the frequency:

$\nu =\frac{3.0*10^8(\frac{m}{s})}{6.40*10^4m}$

$\nu =4.69*10^3Hz$

(since, $\frac{1}{s}=Hz$ )

So, the frequency of the wave is $4.69*10^3Hz$ .

Which memrane lines the abdomino pelvic cavity

Scilla [17]

Answer:

The peritoneum

Explanation:

The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity. The tunica vaginalis is the serous membrane, which surrounds the male gonad, the testis. The two layers of serous membranes are named parietal and visceral. Between the two layers is a thin fluid filled space.

A sample of an unknown gas effuses in 14.4 min. An equal volume of H2 in the same apparatus under the same conditions effuses in

Elena-2011 [213]

Answer:- molar mass of the unknown gas is 71.5 gram per mol.

Solution:- From Graham's law of effusion rates, the rate of effusion of a gas is inversely proportional to the square root of it's molar mass.

When we compare the effusion rates of two gases then the formula for Graham's law is:

$\frac{rate_1}{rate_2}=\sqrt{\frac{M_2}{M_1}}$

In this formula, V stands for volume and M stands for molar mass

Rate is volume effused per unit time. Since, the volumes are same, the formula could be written as:

$\frac{t_2}{t_1}=\sqrt{\frac{M_2}{M_1}}$

let's say in formula, subscript 1 is for hydrogen gas and 2 is for the unknown gas.

Molar mass of hydrogen is 2.02 grams per mol and the time taken to effuse it is 2.42 min. The time taken to effuse the unknown gas is 14.4 min and we are asked to calculate it's molar mass. let's plug in the values in the formula:

$\frac{14.4}{2.42}=\sqrt{\frac{M_2}{2.02}}$

$5.95=\sqrt{\frac{M_2}{2.02}}$

doing squares to both sides:

$35.4=\frac{M_2}{2.02}$

$M_2=35.4*2.02$

$M_2=71.5$

So, the molar mass of the unknown gas is 71.5 grams per mol.
