Answer:

Multi-star system.

Explanation:

Multi star systems are what scientists call systems of stars that are composed by 3 or more stars, this is more than two stars, most of the multi stars systems have only three stars this is because the logistics and forces necessaries to create a system that has 4 or more stars are really complicated and less likely to occur.

Mizar is a quadruple or quaternary star system.
When there is more than two stars, it is called a star system or multiple star system or stellar system.
Depending on the number of stars, they are also called a triple, quadruple or quintuple star system or trinary, ternary, quaternary, quintenary, sextuple, sextenary, septuple or septenary star system.

Which of the following statements is true of proteins?
UkoKoshka [18]

Answer:

The answer is Denaturation is reversible

Explanation:

Denaturation of proteins is the process whereby there is a disruption in the tertiary, quaternary or secondary structure of proteins which causes a conformation change in its action

denaturation is reversible, that is, the proteins can regain their native state when the denaturing influence is removed. This process can be called renaturation.

A certain substance X condenses at a temperature of 123.3 degree C . But if a 650. g sample of X is prepared with 24.6 g of urea
Pavel [41]

Answer:

<u>The molal boiling point elevation constant is 1.59 ≈  1.6</u> Kkgmol^{-1}

Explanation:

To solve this question , we will make use of the equation ,

ΔT_{b} = i*K_{b} *m

<em>where , </em>

  • <em>ΔT_{b} is the change in boiling point of the substance X ( °C or K)</em>
  • <em>i is the Vant Hoff Factor which = 1 in this case ( no unit )</em>
  • <em>K_{b} is the mola boiling point elevation constant of X ( Kkgmol^{-1})</em>
  • <em>m is the molality of the solution which has (NH_{2})_{2} CO as the solute and  X as the solution (molkg^{-1})</em>

  1. ΔT_{b} = 124.3 -123.3 = 1 °C or K;
  2. i=1;
  3. m= \frac{moles of solute}{weight of solvent(kg)}molkg^{-1}

           ∴ m = \frac{\frac{24.6}{60} }{\frac{650}{1000} }

  • <em>as the weight of (NH_{2})_{2} CO is 60g and thus number of moles = \frac{24.6}{60}</em>
  • <em>and the weight of solvent in kg is \frac{650}{1000}</em>

    4. K_{b} ⇒ ?

∴

1=1*K_{b} *\frac{\frac{24.6}{60} }{\frac{650}{1000} }

⇒ K_{b} = 1.59 ≈ 1.6 Kkgmol^{-1}
