Answer:
They had a negative charge
Explanation:
In order to calculate the molar mass of the protein, we may manipulate the ideal gas equation:
PV = nRT, where n is the number of moles. We also know that:
n = m / Mr, where m is mass and Mr is molecular weight
Thus,
Mr = (mRT)/(PV)
Here, the mass is in grams, the temperature is in Kelvin, the pressure is in atm and the volume is in liters, so the molar gas constant is 0.082057.
Mr = (3.6 * 0.082057 * (27 + 273)) / (0.0203 * 0.2)
Mr = 21,828 g/mol
Thus, the Mr of the protein is 2.18 x 10⁴ g/mol
Answer:
- The metal industry uses large quantities of copper sulphate as an electrolyte in copper refining, for copper coating steel wire prior to wire drawing and in various copper plating processes
.
- The mining industry employs it as an activator in the concentration by froth flotation of lead, zinc, cobalt and gold ores
.
- The paint industry uses it in anti-fouling paints and it plays a part in the colouring of glass.
Explanation:
Hello,
In this case, since copper sulphate also known as blue stone, blue vitriol is more commonly found in a pentahydrated cupric sulphate due to its stability. In fact it is often the starting raw material for the production of other varied copper-based salts. Henceforth, you will find three applications.
