Answer:
A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.5 kPa.
<u>The pressure for oxygen is 3 kPa</u>
Explanation:
According to Dalton's Law of Partial Pressure total exerted by the mixture of non-reacting gases is equal to sum of the partial pressure of each gas.
So,
For , a gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure:
Insert the values in :
Answer:
126.4 g of are required
Explanation:
Balanced reaction:
According to balanced reaction-
8 moles of are produced from 2 moles of
So, 8.70 moles of are produced from
moles of
or 2.175 moles of
Molar mass of = 58.12 g/mol
So, mass of required =
= 126.4 g
Hence 126.4 g of are required
Answer:
1.The electrode on the right is positive
2. 0.058V
Explanation:
The above cell is a concentration cell.
A concentration cell is an electrolytic cell that is made of two half-cells with the same electrodes, but differs in concentrations of the solutions. A concentration cell functions by diluting the more concentrated solution and concentrating the more dilute solution, creating a voltage as the cell reaches an equilibrium thereby transferring the electrons from the cell with the lower concentration to the cell with the higher concentration.
In the above cell, electrons flow from the left electrode (less concentrated) to the right electrode (more concentrated). Therefore, the right electrode is the positive electrode (cathode).
Part 2: Please, see the attachment below for the calculations.
Answer:
Cl2, because it gained electrons
Explanation:
2Fe^2+ went from 2+ to 3+
Cl2 went from 0 to -1
Reduction-gain
Oxidation-loss
- means gained and + means loss trust me it doesn't make sense but if you stick to it it'll be a lot easier for you.
