Answer:

k=1.12x10^{-4}s

Explanation:

Hello,

By considering the rate law:

ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\

Solving for the time, we've got:

k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\  \\k=1.12x10^{-4}s

Best regards.

Why did Rutherford conclude that the atom was mostly empty space?
olga nikolaevna [1]
Rutherford came to this conclusion after his Gold-Foil experiment. He found that most of the alpha particales(when released) went straight through the gold foil, of which consisted of atoms. In the middle of the atom theres a small nucleus that has mass and positive charge. Because the nucleus is so small the alpha <span>particles were able to go straight through leading to the conclusion that atoms are mostly empty space. </span>

Describe 2 ways of salting out proteins ​
liubo4ka [24]

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.

HELP!!!!
ale4655 [162]

Answer: Option (b) is the correct answer.

Explanation:

Since energy of reactants is less than the energy of products. Therefore, it means energy is absorbed during the reaction.

As the energy required to break the bonds in the reactants is greater than the energy released when products are formed.  

Therefore, it is an endothermic reaction.

Thus, we can conclude that the statement, it is endothermic because the energy required to break bonds in the reactants is greater than the energy released when the products are formed is correct.
