Hope this helps! I found it when I searched your question.
Given: Initial volume of gas= 15.0 L
Pressure=1.50 atm
Temperature=23°C
Use ideal gas equation as follows:
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature in Kelvin.
First convert the given temperature in Kelvin.
0°C=273.15 K
Thus, 23 °C=296.15 K
Rearranging ideal gas equation to calculate the value of nR as follows:
Now, final pressure is 3.50 atm and temperature is 286°C, converting the temperature into Kelvin,
0°C=273.15 K
Thus, 286 °C=559.15 K
Volume can be calculated using the ideal gas equation as follows:
Putting the value of given pressure and temperature and the above calculated value of nR,
Therefore, volume of at 3.50 atm and 286°C is 12.14 L.
Based in the information given, the data that'll be affected by the error is the value of the solvent data.
It should be noted that the data that'll be affected based on the scenario given is the value of the solvent. When the preparation is kept overnight, there'll be an overflow of the solvent.
In such a case, it'll be difficult to get the correct distance that the solvent travelled. The effect on the calculated Rr is that the <em>calculated Rr</em> will be incorrect due to the error in solvent value.

Answer:
<h3>Cu²+ e ----> Cu+ </h3>
This is not oxidation as it gain electron .
Oxidation reaction means addition of oxygen or removal of hydrogen
or in other words loss of electrons
Mg ----> Mg²+ + 2e
this is oxidation reaction as Mg loss 2e to become +2
Sn³+ -----> Sn4+ + 2e
this is oxidation reaction as it losses electrons
similarly other are also oxidation.
