Answer:

A. High concentration of oxygen in the blood; high concentration of carbon dioxide in the body tissues

Explanation:

Diffusion occurs from a region of higher concentration to a region of lower concentration. Diffusion occurs against a concentration gradient.

High concentration of oxygen in the blood causes oxygen to leave the blood and enter body tissues.  High concentration of carbon dioxide  in the body tissues causes carbon dioxide to leave body tissues and enter the blood.

What’s the IUPAC name
hichkok12 [17]

Answer:

Methyl pentanoate.

Explanation:

Hello there!

In this case, according to the given information, we can see the correct structure will be:

                             O

                              ||

CH3CH2CH2CH2COCH3

Which matches with the structure of an ester due to the -COO- functional group. In such a case, the first part of the name is in function of the right side of the ester, in this case, methyl, followed by the left side, pentanoate, as it has five carbon atoms and is an ester (similar to an inorganic salt, but organic) and therefore, the name will be methyl pentanoate.

Regards!

Anastasy [175]

Explanation:

Molarity=\frac{\text{Moles of compound}}{\text{Volume of solution (L)}}

Moles of compound =

\frac{\text{mass of compound}}{\text{Molar mass of compound}}

We have ;

Volume of solution = 600 mL = 0.600 L ( 1 mL = 0.001 L)

Moles of NaOH = n

Molarity of the solution = 3 M

3M=\frac{n}{0.600 L}

n = 3 M × 0.600 L = 1.800 mol

Mass of 1.800 mole sof NaOH :

1.800 mol × 40 g/mol = 72.0 g

Preparation:

Weight 72.0 grams of sodium hydroxide and add it to the 500 mL of volumetric flask along with some water. Dissolve the all the solute by adding small proportion of water. After the solution becomes clear make the water upto the mark of 500 ml.

Transfer the solution to a bigger beaker  and 100 mL of water more to it.
