Answer:

609g

Explanation:

The translated question is:

What maximum amount of grams of potassium nitrate (V) can be dissolved in 300g of water at 90 °C

<h2>Solution</h2>

To answer the question you need to consultate the solubiity information for potassium nitrate (V), KNO₃.

The attached table contains the solutibility table for KNO₃ at different temperatures.

At 90ºC it is 203g / 100g water.

Then, to calculate the maximum amount of grams of potassium nitrate (V) that can be dissolved in 300g of water at 90 °C, just multiply by the amount of water:

203g / 100g water × 300 g water = 609g ← answer

What is the difference between an exergonic reaction and an endergonic reaction?

Marina CMI [18]

The difference between an exergonic reaction and an endergonic reaction is that an exergonic reaction involves release of energy, while an endergonic reaction involves absorption of energy.

In an exergonic reaction, energy is released to the surroundings. The bonds being formed are stronger than the bonds being broken. In an endergonic reaction, energy is absorbed from the surroundings.

The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

A sample of chlorine gas occupies a volume of 707 ml at 2.90 atm. What is the new pressure in torr if the volume is compressed t

dolphi86 [110]

Answer:

The new pressure is 3850 torr.

Explanation:

The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :

$P_1V_1=P_2V_2$

Here,

$P_1=2.9\ atm$

$V_1=707\ mL$

$V_2=0.533\ L$

Let $P_2$ is the new pressure. So using Boyle's law we get :

$P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{2.9\times 707}{0.533}\\\\P_2=3846.71\ \text{torr}$

$P_2=3850\ \text{torr}$

So, the new pressure is 3850 torr.

Which of the following describes the relationship between acid strength and ka value for weak acids?

Leona [35]

I think the correct answer would be when ka increases, the acid strength increases. Ka is the product of hydronium ions and the [A-] ions concentration over the acid concentration. Therefore, increasing the the Ka, the numerator in the definition would increase as well which correspondingly increase the strength of the acid.
