Which of the following best explains why electrometallurgy is a useful process in many industries?

A.) Electrometallurgy can etch permanent marks and designs into the surfaces of metal products.

B.) Electrometallurgy can create a thin film around metals, preventing rusting and other forms of corrosion.

C.) Electrometallurgy can refine a wide range of impure metals used in manufacturing, wiring, and many other applications.

D.) Electrometallurgy can split water molecules into a cheap source of oxygen gas that can be carried into space and beneath the ocean.

C.) Electrometallurgy can refine a wide range of impure metals used in manufacturing, wiring, and many other applications.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
