Answer:
No
Explanation:
It is given that :
Amount of the clear aqueous solution = 4 L
Temperature of the clear solution = 22°C
The solution remain clear even after an unknown amount of X compound is dissolved in the solution.
Then the water is evaporated under vacuum and the remaining precipitates weighs 0.56 kg.
Therefore, from the above data, we cannot calculate the solubility of the compound X that is added to the clear aqueous solution at 22°C.
The substance which gets dissolved is known as solute and the substance where the solute is dissolved is known as the solvent.
An element's atomic number shows the number of protons in its nucleus.
Step 1. - Scientists first take a look at their empirical evidence and try to explain it.
Step 2. - Scientists test if their explanation or conclusion is logical.
Step 3. - If their explanation is logical, they search for new test that may help them to support their first idea.
The answer for this problem is 22.12. Hope it helped. :)
WORK: 10.5+11.62=22.12
Answer:
0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment
Explanation:
The concentration of the solution is given by :
We have:
Concentration of copper (II) nitrate solution =
The volume of solution = 4.12 mL
1 mL= 0.001 L
Moles of copper (II) nitrate in solution = n
Moles of copper (II) nitrate in solution = 0.0099292 mol
1 Mole of copper(II) nitrate has 1 mole of copper then 0.0099292 moles of copper(II) nitrate will have :
Mass of 0.0099292 moles of copper:
This mass of copper present in the solution is the theoretical mass of copper present in the given copper(II) nitrate solution.
0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment
