The molecule

Schach [20]

Answer:

In the solid phase, the forces of attraction have completely overcome molecular motion, and the movement of the particles has been reduced to vibrating in place. The particles cannot move past one another and are held in a tightly-packed pattern, so there is very little space between the particles.

a compound is found to contain 31.1% sulfur and 68.9% chlorine determine the empirical formula for the sulfur and chlorine sampl

ollegr [7]

Answer:

Empirical formula = S₁Cl₂ = SCl₂

Explanation:

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.

This compound contains 31.1% sulfur and 68.9% chlorine.

That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.

Convert the mass of each element to moles using the molar mass from the periodic table.

Moles of Sulfur = $\frac{31.1}{32.065 } \\$

= 0.9699

Moles of Chlorine= $\frac{68.9}{35.453 } \\$

= 1.9434

Divide each mole value by the smallest number of moles calculated.

Units of sulfur = $\frac{0.9699}{0.9699} \\$

= 1

Units of Chlorine = $\frac{1.9434}{0.9699} \\$

= 2

Empirical formula = S₁Cl₂ = SCl₂

How many grams in total of potassium dichromate are there in a 250 mL bottle filled with 5 ppm solution of it?

nordsb [41]

The mass of is K2CrO7 in the 250 ml of solution is mathematically given as

x=1.25mg of K2CrO7.

Hence, 250 ml of the solution will contain 1.25mg of K2CrO7

Question Parameters:

The total of potassium dichromate are there in a 250 mL bottle filled with 5 ppm solution

Generally the mass of k2CrO7 is mathematically given as

$x=\frac{5mg of k2CrO7 *250ml of solution}{1000ml of solution}$

x=1.25mg of K2CrO7

Therefore,

250 ml of the solution will contain 1.25mg of K2CrO7

Your teacher asked you to identify the stage of mitosis of a specimen under the microscope. You observed that instead of a typic

yKpoI14uk [10]

Answer:

D. Cytokinesis

Explanation:

Mitosis is the cell division that involves the synthesis of two genetically identical daughter cells. Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase. Following this four processes is another called CYTOKINESIS

Cytokinesis, which occurs after nuclear division, is the division of the cytoplasm. According to this question, the observation made when viewing the specimen was that "the cell has a narrow middle part which almost separates into two bulging ends and which looks like the number 8". This described the process of CYTOKINESIS in plant cell specifically.
