Answer:-

Electrocautery Device

Explanation:-

The heat and light produced like a discharge due to a low impedence connection is called arc flash. They can cause substantial damage including fire and injury.

Electrocauterization or electric surgery is the process of destroying tissue with electricity. In this process the electrode is held away from the tissue, so that when the air gap between the electrode and the tissue is ionized leading to an electric arc discharge.

Here a low impedence is used to since a return electrode burn will occur if the heat produced, over time, is not safely dissipated by the size or conductivity of the patient return electrode.

Hence an arc flash can result from a Electrocautery Device if proper precautions are not taken.

Answer:

copper metal is a product of the cell reaction.

Explanation:

In writing the line notation of a cell reaction, we ought to recall that the anode is placed at the left hand side of the notation while the cathode is placed at the right hand side of the notation.

If we look at the line notation shown in the question, we will realize that the Cu2+ (aq) | Cu(s) half cell is the cathode and that copper metal is the product of the reaction as shown by the notation.

What is the number of grams in 3.2 moles of CuSO4×5H2O

son4ous [18]

Hey there!:

Molar mass CuSO4*5H2O = 249.68 g/mol

Therefore:

1 mole CuSO4*5H2O ---------------- 249.68 g

3.2 moles --------------------------------- ?? ( mass of CuSO4*5H2O )

mass CuSO4*5H2O = 249.68 * 3.2

mass CuSO4*5H2O = 798.97 g

Hope that helps!
