Answer:
Kindly check the attachment for the diagram representing the cell and showing all necessary components including: anode, cathode, electron flow, cation flow and anion flow.
Explanation:
So, the reaction in the concentration cell is given below as;
Cu2+(1.00 M) → Cu2+(0.0100 M).--(1).
The anode = Cu2+(0.0100 M) because it has lesser Concentration, thus, lesser potential value.
Cathode = Cu2+(1.00 M) because it has higher Concentration, hence higher potential value.
It must be noted that in the digaram depicting the Reaction, the electrons moves from the anode part of the cell to the cathode part of the cell and this is done through an external circuit. The following are the things that happens at each electrode;
At the Anode: in here is where oxidation occurs and Cu^2+ is released into the solution.
At the cathode: in here is where the reduction occur and the Cu^2+ moves in the direction to where the Cu electrode is, thus, causing the deposition of Cu.
Answer:
B.Bronze is harder than copper, so it retains a cutting edge sharper than that of copper.
Explanation:
The importance of bronze in the history of the human kind can not be only measured in the durability but the help that it provided to our ancestors, the things they were allowed to do once they dicovered how to mold it, and the tools that they produced and made many every day tasks easier for them and the ability of bronze to mantain the cutting edge longer than copper was one of the main reasons why it took its places in the fabrication of many tools.
The question is incomplete, here is the complete question:
A murexide soution has a concentration of and an absorbance of 1.850 and the path length is 1 cm. What is the molar absorptivity of the solution?
<u>Answer:</u> The molar absorptivity coefficient is
<u>Explanation:</u>
To calculate the molar absorptivity coefficient, we use the equation given by Beer-Lambert law, which is:
where,
A = absorbance = 1.850
= molar absorptivity coefficient = ?
C = concentration of the solution =
l = path length = 1 cm
Putting values in above equation, we get:
Hence, the molar absorptivity coefficient is
If you increase the temperature the air will try to expand. Since it is sealed and the air can't expand, it will apply higher pressure to the can because it will want to burst out. It works the other way around, if you cool it down it will lower the pressure.
At convergent boundaries, tectonic plates Collide with each other. The events that occur at these boundaries are linked to the types of plates (oceanic or Connentaux that are interacting. oceanic crust gets bent and pulled under, or Subducted, beneath the lighter and thicker continental crust.
