Lee and some other students working with Dr. Yung were conducting an experiment and ended up with some confusing results. In the

experiment, each student combined sodium and hydrogen chloride, but, as shown in the table below, each student ended up with different results. Lee is trying to determine what happened.
In a few minutes, you will see a video of what happened when Lee combined two substances. Before you watch the video, see if you can predict why each student ended up with different results.

Student's name Starting substances Ending substances
Lee sodium and hydrogen chloride hydrogen and sodium chloride
Vera sodium and hydrogen chloride hydrogen, sodium chloride, and sodium
Domingo sodium and hydrogen chloride hydrogen, sodium chloride, and hydrogen chloride


Why do you think Vera and Domingo ended up with three substances after the chemical reaction while Lee only ended up with two?

Convert molecules of vitamin d (molar mass 384.7 g/mol) to grams of vitamin d.
velikii [3]

The 6.023 * 10²³  molecule means  384.7 grams of Vitamin D.

<h3>What is a mole ?</h3>

A mole is a universal unit used to measure large number of atoms , molecules of an element.

one mole is equal to the Avogadro's Constant.

Mole is equal to the ratio of the mass of a compound to its molecular weight

It is given that Vitamin D is present

no. of molecule = 6.023 * 10²³

6.023 * 10²³ molecule constitutes of 1 mol

1 mole  is equal to the molar mass of a compound/ element

Therefore 1 mole = 384.7grams of Vitamin D

and hence 6.023 * 10²³  molecule means 384.7 grams of Vitamin D.

The graph shows a relationship between volume and temperature. Which of the following statements is true?
Marat540 [252]

Answer:

The graph shows a directly proportional relationship between volume and temperature and represents Charles' Law.

Explanation:

The relation between volume and temperature is given by :

Ideal gas law, PV = nRT

Where

P is pressure

V is volume

R is gas constant

T is temperature

As volume and temperature have direct relationship. Charles law states that there is a direct relationship between volume and temperature. The correct option is (a).
