g You are preparing a series of samples to be analyzed by Spectrophotometry. For one sample, you take 5 mL of potassium permanganate that is at a stock concentration of 12 mg/mL and mix it with 5 mL of water. What is the final concentration of potassium permanganate in this sample

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium

In medium-sized stars such as the sun, nuclear fusion almost always means the fusing of nuclei to form , but larger stars can produce elements as heavy as
