A chemistry student is given 600. mL of a clear aqueous solution at 27.° C. He is told an unknown amount of a certain compound X

DiKsa [7]

Answer: No

Explanation:

Firstly, the molar mass of the dissolved solid is not given. This is necessary to calculate the number of moles present in solution. Secondly, solubility always has to do with temperature and the specified temperature is 27°c and not 21°c. This makes it impossible to calculate the solubility at 21°c. Further information must supplied before the solubility at 21°c can be accurately calculated.

Given the statements below, choose the one that is true about one-celled living things.

grandymaker [24]

Answer: The adult stage for one-celled organisms is usually extremely long.

Explanation:

The first one is false, I'm no expert, but I'm pretty sure that there is some yeast that don't produce spores, even in normal conditions.

The third is false, Algae can be unicellular <em>and </em>multicellular.

The fourth is false, All the Algae in the world is close to <em>half</em> of the ogygen in the world.

So that leaves the second, The adult stage is usually long for one-celled organisms.

How many grams of NaCI are present in 11.00 moles

Amiraneli [1.4K]

Answer: 642.93 g of NaCl

Explanation:

11.00 mol NaCl x __58.448 g__ = 642.928 g of NaCl

1 mol NaCl

I would round to 642.93 g of NaCl, but round to however many significant figures asked for.

My chemistry teacher made this map (image attached) to teach us how to do conversions. Just follow the map. I think it's pretty straight forward. I hope this helps.

Select the structure that corresponds to the molecule name:

Pepsi [2]

Answer:

Option B

Explanation:

The name of the molecule is;

1,1,1,3,3,3-Hexachloropropanone

Now, we can see that it contains propanone which is also called acetone. So it will have a double bond with Carbon(C) and Oxygen (O).

Option B has that double bond between C and O that indicates it propanone or acetone.

Thus, it is the correct option.
