Answer:

About 170-180 grams of potassium nitrate are completely dissolved in 100 g.

Explanation:

Hello!

In this case, according to the reported solubility data for potassium nitrate at different temperatures on the attached picture, it is possible to bear out that about 170-180 grams of potassium nitrate are completely dissolved in 100 g; considering that the solubility is the maximum amount of a solute that can be dissolved in a solvent, in this case water.

Best regards!

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.

If a substance is covalent, then it likely will

svet-max [94.6K]

Answer : If a substance is covalent, then it is likely to melt easily and fast, it may be composed of two or more non-metals which share a covalent bonding between them and it will not conduct electricity.

It is seen that covalent substances are made up of two or more non-metals which share a covalent bond between them. They are found to melt easily and when dissolved in water they are seen to be insoluble. They are also not good conductors of electricity as there is no free electron available to conduct electricity.

How does deforestation affect the carbon cycle

Mama L [17]

Deforestation is the mass cutting of trees. Much of our oxygen comes from trees so if we cut down the trees then their will be more carbon dioxide in the air instead of the needed amount of oxygen.
