Do strong acid and strong base have similar effects on protein solubility and denaturation

1 answer:

7 0

Both strong acid and strong base will alter the solubility and the nature of a protein. This is because, adding a strong acid or base to a protein will drastically change the pH of the protein and this will leads to formation of precipitation and denaturation of the protein.

What types of substances dissolve in water and isopropanol

exis [7]

The substances that would dissolve in water and isopropanol would be polar substances. This is by the virtue like dissolves like. Water and isopropanol are polar solvents which would mean polar molecules would be dissolved in them. Polar molecules contains electrical poles which allows them to be dissolve into polar solvents.

Retinol is 83.84% c, 10.58% h, and 5.58% o by mass. what is the molecular formula of retinol? add the missing subscripts.

ikadub [295]

Answer is: molecular formula of retinol is C₂₀H₃₀O.
n(C) = 83,84 g ÷ 12 g/mol.
n(C) = 6,99 mol.
n(H) = 10,58 ÷ 1,008 g/mol.
n(H) = 10,5 mol.
n(O) = 5,58 g ÷ 16 g/mol.
n(O) = 0,348 mol.
n(C) : n(H) : n(O) = 6,99 mol : 10,5 mol : 0,348 mol /:0,348.
n(C) : n(H) : n(O) = 20 mol : 30,1 mol : 1.

How many milliliters of 2.15 wt% dimethylglyoxime solution should be used to provide a 50.0% excess for Reac- tion 7-2 with 0.99

Lilit [14]

This is an incomplete question, here is a complete question.

How many milliliters of 2.15 wt% dimethylglyoxime solution should be used to provide a 50.0% excess for Reaction 7-2 with 0.998 4 g of steel containing 2.07 wt% Ni? Assume that the density of the dimethylglyoxime solution is 0.790 g/mL.

Answer : The volume of solution is, 7.195 mL

Explanation :

First we have to calculate the mass of Ni.

Mass of Ni = $0.998g\times 2.07\% =0.998g\times \frac{2.07}{100}=0.0206g$
