Answer:
If the chef is in a hurry we would assume he would want the pan to heat up so copper
Explanation:
Hey there!:
Option B,CO2 at 353K
*Since most collisions means that highest kinetic energy.
*As we know that kinetic energy of gas molecules is directly proportional to absolute temperature
*More the temperature, More the kinetic energy.
* Hence B is the correct answer as it has highest temperature.
Hope this helps!
Explanation:
a) The presence of sulfate ions in a solution can be confirmed by the reaction of barium chloride in an acidic medium.
The balanced chemical equation of the reaction is shown below:
Hence, the white precipitate is barium sulfate and its formation with the ionic equation is shown below:
b) The presence of copper (II) ions can be confirmed by the following test:
Add potassium iodide solution to copper (II) solution.
Then a white ppt of cuprous iodide along with the liberation of iodine is observed and the entire solution attains brown color.
The chemical equation of the reaction is shown below:
c)(i)Due to this reaction, the blue color of the solution becomes white.
Reddish-brown copper is deposited at the bottom of the container.
(ii)In this reaction, zinc is oxidized.
d) (i) Copper is produced at the cathode.
(ii)
(iii) The reaction that takes place at the cathode is reduction.
Reduction is gaining of electrons.
A chemical symbol designates an element that belongs to the periodic table.
A chemical formula combines two or more symbols and it represents a chemical compound. We notice that the chemical symbols are followed oftenly by a subscript that represents the mole proprtions of next element.
