Copper is washed with ethanol and ether to remove any remaining impurities or contaminants that may be present on the surface. This helps to ensure the purity of the copper sample for further analytical or experimental purposes. Ethanol and ether are typically used because they are effective solvents for cleaning and are easily evaporated, leaving behind a clean copper surface.

How many grams of Cu(NO3)2 will be produced if you start with 4.2 grams of cu?
To determine the number of grams of Cu(NO3)2 produced, you need to consider the molar ratio between Cu(NO3)2 and Cu. Firstly, convert the 4.2 grams of Cu to moles using the molar mass of Cu. Then, use the balanced chemical equation to find the moles of Cu(NO3)2 produced. Finally, convert the moles of Cu(NO3)2 to grams using its molar mass.
What volume in drops of 16M HNO3 is required to react with 0.0214grams of Cu metal?
To find the volume of 16M HNO3 required to react with 0.0214g of Cu metal, you need to calculate the moles of Cu. Then, using the balanced equation for the reaction between Cu and HNO3 (Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O), you can determine the moles of HNO3 needed. Finally, using the molarity of the HNO3 solution, you can calculate the volume in drops.
How do you convert 12.54 g of Cu to atoms?
To convert grams of Cu to atoms, first calculate the molar mass of Cu from the periodic table (63.55 g/mol). Next, divide the given mass (12.54 g) by the molar mass to get moles of Cu. Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
Copper will react with silver nitrate to form copper nitrate and silver From this reaction 127.1 grams of copper will produce how many grams of silver?
The balanced equation for the reaction is: Cu + 2AgNO3 -> Cu(NO3)2 + 2Ag Calculate the molar mass of Cu and Ag (Cu = 63.55 g/mol, Ag = 107.87 g/mol). Using the molar ratio of Cu to Ag (1:2), convert the mass of Cu to moles, then use the molar ratio to find the moles of Ag produced. Finally, convert moles of Ag to grams using the molar mass of Ag to find the grams of silver produced.

What does ethanol due to copper two?
Ethanol can react with copper(II) ions (Cu²⁺) in various ways, primarily through coordination and complexation. Ethanol can act as a ligand, forming complexes with copper ions. This interaction can influence the properties of the copper solution, such as its color and reactivity, and can be utilized in various chemical processes, including catalysis and organic synthesis. Additionally, ethanol can reduce copper(II) ions to copper(I) ions in certain conditions.

How do you convert cu in into cu yards?
To convert cubic inches (cu in) to cubic yards (cu yd), divide the volume in cubic inches by 46,656, since there are 46,656 cubic inches in one cubic yard (1 cu yd = 3 ft x 3 ft x 3 ft = 27 cu ft, and 1 cu ft = 1,728 cu in). The formula is: cu yd = cu in ÷ 46,656. For example, if you have 1,000 cu in, you would calculate 1,000 ÷ 46,656, which equals approximately 0.0214 cu yd.
