Describe how amino acids are categorized by their chemical properties

1 answer:

5 0

Amino acids are categorized by their chemical properties on the basis of the sequence of side chain (R group).

<h3>What are amino acids?</h3>

Amino acids are known as the 'building blocks of the life' as they help in the formation of proteins inside the body.

Side chain of amino acids is specific in nature and are known by the name of R group, these R groups are attached with the alpha carbon atom. R groups characterizes below properties of the molecule:

Shape
Size
Charge and
Reactivity

Hence R group describes the chemical properties of amino acids.

You are given a stock solution of 500.0 mL of 1.00M magnesium chloride solution. Calculate the volume of the stock solution you

alexgriva [62]

Answer:

$50\; \rm mL$ of the stock solution would be required.

Explanation:

Assume that a solution of volume $V$ contains a solute with a concentration of $c$ . The quantity $n$ of that solute in this solution would be:

$n = c \cdot V$ .

For the solution that needs to be prepared, $c = 0.20\; \rm M = 0.20\; \rm mol \cdot L^{-1}$ . The volume of this solution is $V = 250.0\; \rm mL$ . Calculate the quantity of the solute (magnesium chloride) in the required solution:

$\begin{aligned}n &= c \cdot V \\ &= 0.20\; \rm mol \cdot L^{-1} \times 250.0\; \rm mL \\ &= 0.20\; \rm mol \cdot L^{-1} \times 0.2500\; \rm L \\ &= 0.050\; \rm mol\end{aligned}$ .

Rearrange the equation $n = c \cdot V$ to find an expression of volume $V$ , given the concentration $c$ and quantity $n$ of the solute:

$\displaystyle V= \frac{n}{c}$ .

Concentration of the solute in the stock solution: $c(\text{stock}) = 1.00\; \rm M = 1.00\; \rm mol \cdot L^{-1}$ .

Quantity of the solute required: $n = 0.050\; \rm mol$ .

Calculate the volume of the stock solution that would contain the required $n = 0.050\; \rm mol$ of the magnesium chloride solute:

$\begin{aligned}& V(\text{stock}) \\ &= \frac{n}{c(\text{stock})} \\ &= \frac{0.050\; \rm mol}{1.00\; \rm mol \cdot L^{-1}} \\ &= 0.050\; \rm L \\ &= 50\; \rm mL\end{aligned}$ .

Calculate Rations. A transformer has ten turns of wire on the input side and 50 turns of wire on the output side. if the input v

Illusion [34]

Answer:

Output voltage = 600 V

Explanation:

Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.

Number of input turns/Number of output turns = Voltage of input/voltage of output

10/50 = 120V/voltage of output

Voltage of output = 120 V/0.2

Voltage of output = 600 V

Consider the following reaction:

rusak2 [61]

Answer:

1. a) 0,18

2. e) The reaction proceeds to the left, forming more BrCl(g).

Explanation:

1. In a gas reaction as:

2SO₂(g) +O₂(g) ⇄ 2SO₃(g)

it is possible to convert kp to kc using:

kp = kc (RT)^Δn

Where kp is gas equilibrium constant, kc is equilibrium constant (13), R is gas constant (0,082atmL/molK), T is temperature (900K), and Δn is number of moles of gas products - number of moles of gas reactants (That is 2 - (2+1) = -1). Replacing:

kp = 13×(0,082atmL/molK×900K)^-1

2. Based on Le Chatelier's principle, the change in temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system. For the reaction:

2 BrCl(g) ⇄ Br₂(g) + Cl₂(g).

The addition of 0,050M of each compound cause <em>the reaction proceeds to the left, forming more BrCl(g)</em> because based on the reaction, you need two moles of BrCl per mole of Br₂(g) and Cl₂(g) to keep the system in the same. But you are adding the same proportion of moles of each compound.

I hope it helps!
