Answer:
A. Perchloric acid and potassium hydroxide
B. Trioxonitrate V acid and Cesium hydroxide
C. Hydroiodic acid and calcium hydroxide
Explanation:
An acid reacts with a base to form salt and water. The acid and the base that reacted for each of the compounds have been written in the answer above. The reaction equations are given below:
A. HClO4 (aq) + KOH (aq) ———> KClO4 (aq) + H2O (l)
B. HNO3 (aq) + CsOH (aq) ———-> CsNO3 (aq) + H2O (l)
C. 2HI (aq) + Ca(OH)2 (aq) ———> CaI2 (aq) + 2H2O (l)
The question is incomplete, here is the complete question:
Consider the following two-step process (unbalanced). How many moles of water can be formed from 0.680 moles of ?
Enter your answer numerically to three siginificant figures.
<u>Answer:</u> The amount of water formed from given amount of nitrogen gas is 1.38 moles
<u>Explanation:</u>
We are given:
Moles of nitrogen gas = 0.46 moles
The balanced chemical equation follows:
.......(1)
.......(2)
<u>From equation 1:</u>
By Stoichiometry of the reaction:
1 mole of nitrogen gas produces 2 moles of ammonia
So, 0.46 moles of nitrogen gas will produce = of ammonia
<u>From equation 2:</u>
By Stoichiometry of the reaction:
4 moles of ammonia produces 6 moles of water
So, 0.92 moles of ammonia will produce = of water
Hence, the amount of water formed from given amount of nitrogen gas is 1.38 moles
The amount of KNO₃ precipitated out of solution when you cooled the solution from 100°C to -22°C is obtained from the solubility curve
<h3>What is a solubility curve?</h3>
A solubility curve is a curve of the solubility of a solute against temperature.
The solubility curve shows that the solubility of different solute at different temperatures.
The solubility curve of KNO₃ is as shown. Solubility at 100 °C and -22 °C is not shown in the curve.
However, the amount of KNO₃ precipitated out of solution when cooled the solution from 100 °C to -22 °C can be determined by subtracting the amount of solute dissolve at -22 °C from that dissolved at 100 °C.
In conclusion, the solubility curve is used to determined the amount of solute dissolved in a given volume of solvent at different temperatures.
