Evaporation changes liquid water to gas
Explanation:
Precipitation exists in snow, rain, sleet, many forms liquid or solid but NOT gas.
Evaporation is from a liquid to a gas change, also called vaporization.

To determine the concentration of a sodium thiosulfate solution as in this experiment, a student pipetted 25.0 mL of 0.0100 M potassium iodate (KIO3) solution into a 125 mL Erlernmeyer flask. Potassium iodide and sulfuric acid were added as in this experiment. The titration needed 15.21 mL of the sodium thiosulfate to reach the end point. What is the concentration of the sodium thiosulfate solution
Answers
Answer:
0.0986M is the concentration of the Na₂S₂O₃ solution
Explanation:
Potassium iodate, KIO₃, reacts with sodium thiosulfate, Na₂S₂O₃, as follows:
KIO₃ + 6Na₂S₂O₃ +5KI + 3H₂SO₄ → 3H₂O + 3K₂SO₄ + 3Na₂S₄O₆ + 6NaI
To solve this question we must find the moles of sodium thiosulfate that reacts as follows:
Moles KIO₃:
0.0250L * (0.0100mol / L) = 2.5x10⁻⁴moles KIO₃
Moles Na₂S₂O₃:
2.5x10⁻⁴moles KIO₃ * (6mol Na₂S₂O₃ / 1mol KIO₃) = 1.5x10⁻³ moles Na₂S₂O₃
Molar concentration:
1.5x10⁻³ moles Na₂S₂O₃ / 0.01521L =

Karl-Anthony is trying to plate gold onto his silver ring. He constructs an electrolyte cell using his ring as one of the electrodes. He runs this cell for 90.6 minutes at 213.8 mA. How many moles of electrons were transferred in this process?
Answers
Answer:
0.012 mole of electron
Explanation:
From the question given above, the following data were obtained:
Time (t) = 90.6 minutes
Current (I) = 213.8 mA
Number of mole of electrons =?
Next, we shall convert 90.6 mins to seconds. This can be obtained as follow:
1 min = 60 s
Therefore,
90.6 mins = 90.6 × 60
90.6 mins = 5436 s
Next, we shall convert 213.8 mA to A. This can be obtained as follow:
1000 mA = 1 A
Therefore,
213.8 mA = 213.8 mA × 1 A / 1000 mA
213.8 mA = 0.2138 A
Next, we shall determine the quantity of electricity used in the process. This can be obtained as follow:
Time (t) = 5436 s
Current (I) = 0.2138 A
Quantity of electricity (Q) =?
Q = it
Q = 0.2138 × 5436
Q = 1162.2168 C
Next, the equation for the reaction.
Au⁺ + e —> Au
From the balanced equation above,
1 mole of electron was transferred.
Recall:
1 faraday = 96500 C = 1 e
Thus,
96500 C of electricity is needed to transfer 1 mole of electron.
Finally, we shall determine the number of mole electrons transferred by the application of 1162.2168 C of electricity. This can be obtained as follow:
96500 C of electricity is needed to transfer 1 mole of electron.
Therefore,
1162.2168 C of electricity will transfer = 1162.2168 / 96500 = 0.012 mole of electron
Thus, 0.012 mole of electron was transferred in the process.
Following are the calculation to the moles of electrons that transferred in the process:
Given
Current flows
time[tex]= 90.6\ min = 90.6 \times 60\ sec= 5436 \ sec\\\\[/tex]
For Step 1:
Calculating the Total charge flown in the given time:
For Step 2:
Charge on a single electron
So:
Following are the calculation to the charges of electrons:
Following are the calculation to the electrons transferred:
[tex]=\frac{(726.38\times 10^{19})}{ (6.023 \times 10^{23})}\\\\= 120.60\times 10^{-4}\ moles\\\\[/tex]

What is the percent yield of LiCl if I produced 30.85g LiCl and my theoretical yield was calculated to be 35.40g LiCl?
Answers
Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
[tex]\frac{Actual}{Theoretical} *100[/tex]
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
[tex]\frac{30.85}{35.40} *100\\\\ =87.15[/tex]
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.
Consider the Fischer ester synthesis of methyl benzoate from benzoic acid and methanol in the presence of sulfuric acid as a catalyst. A reaction was performed in which 3.8 g of benzoic acid was reacted with excess methanol to make 2.0 g of methyl benzoate. Calculate the theoretical yield and percent yield for this reaction.
Answers
Answer:
48.8%
Explanation:
The reaction has a 1:1 mole ratio so;
Number of moles of benzoic acid reacted = mass/molar mass = 3.8 g/122.12 g/mol = 0.03 moles
So;
0.03 moles of methyl benzoate is formed in the reaction
Mass of methyl benzoate formed = 0.03 moles * 136.15 g/mol = 4.1 g
percent yield = actual yield/theoretical yield * 100/1
percent yield = 2.0 g/4.1 g * 100 = 48.8%
