  • Since the above organic compound is an compound with only one saturated bond, It can be considered as a single bond compound, and hence we can conclude that as alkane.
  • It also has 5 carbon atoms, so it is termed as pentane.
  • From right to left we have to number the atoms, and 2 nd carbon atom contain Cl atom so it is termed as 2-Chloro and in the 4th position carbon atom contains 2 methyl groups, so it is termed as, 2-Chloro-4,4-dimethylpentane.

Which of the substances in the chart has the least density?
3241004551 [841]
Answer:
            Option-D (Piece of Wood) is the correct answer.

Explanation:
                   Density is related to mass and volume as,

                             Density  =  Mass / Volume
For Wood,
                             Density  =  42.5 / 50

                             Density  =  0.85

You can calculate remaining densities by yourself. Among all the density of Piece of Wood is the least.

The side chain (r group) of the amino acid serine is ch2oh. The side chain of the amino acid leucine is ch2ch(ch3)2. Where would
wel

The answer is leucine would be in the interior, and serine would be on the exterior of the globular protein.

The side chain (R group) of the amino acid serine is CH₂OH. The side chain of the amino acid leucine is CH₂CH(CH₃)₂. In globular protein, leucine found in the interior, and serine found on the exterior. The nature of side chain decides the amino acid position in the globular protein , as CH₂CH(CH₃)₂ this is hydrophobic and CH₂OH is hydrophlic.

How many grams of sodium hydroxide are needed to make 250. Ml of a 7.80 m solution?
sashaice [31]
<h3><u>Answer;</u></h3>

= 78 g of NaOH

<h3><u>Explanation;</u></h3>

Concentration = Moles of solute/Volume of solution

Thus;

Moles of the solute = Volume × Concentration

                                = 7.80 Moles/L × 0.250 L

                                 = 1.95 moles

But; 1 mole of NaOH = 40.0 g

Thus;

Mass of NaOH = moles × molar mass

                         = 1.95 moles × 40 g/mole

                        <u> = 78 g of NaOH</u>
