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:
C . causes environmental acidification due to production of sulfuric acid.
Answer:
Sucrose (C12H22011) will not let a lightbulb light in water
Explanation:
Sucrose is too soluble to allow a lightbulb to light.
Answer:
c. C-F.
Explanation:
Hello, to know the type of bond, you must subtract the electronegativities for each element forming the bond:
a. C-N=3.04-2.55=0.49
b. C-C=2.55-2.55=0
c. C-F=3.98-2.55=1.43
d. C-H=2.55-2.2=0.35
Thus, since for an electronegativity difference between 0.7 and 1.7, the bond is polar, the highest number (most polar), based on calculations is 1.43, that is for c. C-F.
Best regards.
Hi there!
All gasses and engines need fuel to burn because the heat or chemical reaction from the burning fuels are converted into different types of energy that fuel (or help fuel) the engine or gas.
Hope this helps!
