Describe 2 ways of salting out proteins ​

Chemistry
1 answer:
liubo4ka [24]2 years ago
8 0

The phenomenon known as "salting-out" occurs at very high ionic strengths, when protein solubility declines as ionic strength rises. As a result, salting out may be used to segregate proteins according to how soluble they are in salt solutions.

Because large levels of sodium chloride disturb the bonds and structure of the active site, the rate of enzyme activity will gradually decrease as the concentration of sodium chloride rises. As a result, some of the active sites get denaturized and the starch loses its ability to attach to them. As more enzymes get denatured and eventually cease to function, enzyme activity will steadily wane.

A rectangular block of zinc was found to be 11.014 cm wide, 0.2481 m high, and 523.735 mm deep.
ehidna [41]

From the stoichiometry of the problem, 2.01  × 10^5 g of zinc phosphate is produced.

<h3>What is volume?</h3>

Volume is the product of width, height and depth. The significant figures of the width, height and depth are 5, 4 and 6 respectively.The volume of the box is; 11.014  × 10^-2 m  × 0.2481 m × 523.735 × 10^-3 = 0.01431 m^3 or 14310 cm^3 or 0.5053ft^3.

Density of zinc = 7.140 g / cm3

Volume of zinc = 14310 cm^3

Mass of zinc = 7.140 g / cm3 ×  14310 cm^3 = 102 Kg

Moles of Zinc = mass /molar mass = 102 × 10^3/65 g/mol = 1569 moles

There are 195 g of zinc in  386 g zinc phosphate

102 × 10^3 g of Zn will produce  x g

x = 102 × 10^3 g ×  386 g / 195 g

x = 2.01  × 10^5 g of zinc phosphate

1. If 20 moles of HCl was placed in 40 liters of an
anastassius [24]

Answer:

A) 0.50 M

Explanation:

The computation of the number of molarity of the NaOH is given below:

As we know that

Molarity = Moles ÷ liters

where

Moles is 20

And, the liters is 40

So, the molarity is

= 20 ÷ 40

= 0.50 M

hence, the molarity of the NaOH  solution is 0.50 M

Therefore the A option is correct
