Answer : The sketch of two amino acids side by side are shown below.

Explanation :

Amino acid : Amino acid are the acid that contains two functional groups which 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.

Hence, the sketch of two amino acids side by side are shown below.

Jason measures three values of density for his unknown. The values he obtains are: 1.019 g/mL 1.498 g/mL 1.572 g/mL What is the

jok3333 [9.3K]

Answer: The average of the densities of the given measurements is 1.363 g/mL

Explanation:

The equation used to calculate density of a substance is given by:

$\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}$

We are given:

First measured value of density, $d_1$ = 1.019 g/mL

Second measured value of density, $d_2$ = 1.498 g/mL

Third measured value of density, $d_3$ = 1.572 g/mL

Putting values in above equation, we get:

$\rho_{mix}=\frac{d_1+d_2+d_3}{3}$

$\rho=\frac{1.019+1.498+1.572}{3}\\\\\rho=1.363g/mL$

Hence, the average of the densities of the given measurements is 1.363 g/mL

A. 1720 kJ B. 125.6 kJ C. 3440 kJ D. 4730 kJ

Feliz [49]

Answer:

Q = 3440Kj

Explanation:

Given data:

Mass of gold = 2kg

Latent heat of vaporization = 1720 Kj/Kg

Energy required to vaporize 2kg gold = ?

Solution:

Equation

Q= mLvap

It is given that heat required to vaporize the one kilogram gold is 1720 Kj thus, for 2 kg

by putting values,

Q= 2kg × 1720 Kj/Kg

Q = 3440Kj

which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?

NeTakaya

The given question is incomplete. The complete question is as follows.

Which of the following best helps explain why an increase in temperature increases the rate of a chemical reaction?

(a) at higher temperatures, high-energy collisions happen less frequently.

(b) at low temperatures, low-energy collisions happen more frequently.

(c) at higher temperatures, less-energy collisions happen less frequently.

(d) at higher temperatures, high-energy collisions happen more frequently

Explanation:

When we increase the temperature of a chemical reaction then molecules of the reactant species tend to gain kinetic energy. As a result, they come into motion which leads to more number of collisions within the molecules.

Therefore, chemical reaction will take less amount of time in order to reach its end point. This means that there will occur an increase in rate of reaction.

Thus, we can conclude that the statement at higher temperatures, high-energy collisions happen more frequently, best explains why an increase in temperature increases the rate of a chemical reaction.

What is the density of a cube of water measuring 2cmX4cmX1cm, with a mass of 8g?

Vinil7 [7]

The actual formula for volume for a cube is the length multiplied by the width and then multiplied by the height. Since all three measurements are the same, the formula results in the measurement of one side cubed. For the example, 5^3 is 125 cm^3. Multiply the volume by the known density, which is the mass per volume.
