Answer : The process illustrated in this drawing is, condensation.

Explanation :

Amino acid : The acid that contains two functional groups that are carboxylic group, -COOH and ammine group, -NH_2.

When the two or more that two amino acids join together with the help of peptide bond, they produces polypeptide chain or protein.

The bond present between the two amino acid is called a peptide bond.

The peptide bond is a chemical bond that is formed between the two molecules  when the nitrogen of one amino acid react with the carbon of another amino acid by releasing a water molecule. This is a dehydration synthesis or condensation reaction.

Condensation reaction : It is a reaction in which two molecules combine to form a larger molecule and producing water as a byproduct.

Hence, the process illustrated in this drawing is, condensation.

Murrr4er [49]

Answer:

<em>56.4 m</em>

<em></em>

Explanation:

volume increases by factor of 6, i.e \frac{V2}{V1} = 6

Initial temperature T1 at bottom of lake =  5.24°C = 278.24 K

Final temperature T2 at top of lake = 18.73°C = 291.73 K

NB to change temperature from °C to K we add 273

Final pressure P2 at the top of the lake = 0.973 atm

Initial pressure P1 at bottom of lake = ?

Using the equation of an ideal gas

\frac{P1V1}{T1} = \frac{P2V2}{T2}

P1 = \frac{P2V2T1}{V1T2} = \frac{0.973*6*278.24}{291.73}

P1 = 5.57 atm

5.57 atm = 5.57 x 101325 = 564380.25 Pa

Density Ρ of lake = 1.02 g/cm^{3} = 1020 kg/m^{3}

acceleration due to gravity g = 9.81 m/s^{2}

Pressure at lake bottom = pgd

where d is the depth of the lake

564380.25 = 1020 x 9.81 x  d

d = \frac{564380.25}{10006.2} = <em>56.4 m</em>

Calculate the standard potential for a cell that employs the over-all cell reaction: 2Al(s) + 3 I2(s)→2 Al+3 + 6 I- From reducti
Valentin [98]

Answer:

Explanation:

2Al(s) + 3 I₂(s)   →    2 Al⁺³    +     6 I⁻

Aluminium is oxidised and iodine is reduced .

so cell potential = Ereduction - Eoxidation

Al⁺³ + 3e = Al          -  1.66 V

I₂ + 2 e = 2 I⁻             0.54 V

=  .54 - ( - 1.66 )

= 1.66 + .54

= 2.2  V
