Can you use evaporation to separate the components of coca-cola? Explain in 2-3 sentences.

Help with the following question

Please answer parts a and b

Which chemical or functional group helps a molecule dissolve in water?  NH2 (amino group) fats hydrocarbon tails (side chains) CH3 (methyl group)

Identify the false statement regarding water. A homogeneous mixture is a solution where only one phase can be seen. Below 0 °C the H-bonds cause the water molecules to form a crystal lattice structure. Water can ionize into H+ and OH- ions. Water pipes have often rupture in the summer as the heat increases the kinetic energy and water becomes less dense. Hydrogen bonding gives water its unusual properties.

Please help with both questions!

2. Why are similar sized organic molecules that contain oxygen atoms more soluble in water than organic molecules that only contain carbon and hydrogen atoms? Give examples to support your explanation

The boiling point of 20.0 g of Ca(NO 3 ) 2 dissolved in 500.0 g of water would be ? kb =0.512^ C/m

1. Water is necessary for life on Earth. Water is made up of hydrogen and oxygen atoms (H2O); however, biological life in water depends on another form of oxygen. These organisms need molecular oxygen (O2), which they use to perform aerobic respiration. This molecular oxygen fits into spaces between water molecules and is available for aquatic organisms to use. How do you think molecular oxygen gets into the water? Choose two of the following choices. Select all that apply: From the oxygen atoms that are part of the water molecules. From oxygen that dissolves into water from the atmosphere. From oxygen that is given off by aquatic organisms during respiration. From oxygen that is given off by aquatic plants during photosynthesis.

The minimum level of mercury levels in water considered safe is 1 part per billion (ppb) by weight. Ifyou did an analysis and found that the concentration was 0.59 parts per billion. What quantity of mercuryin grams was present in 8.52 L of the water, the density of which is 0.998 g/ml? (1 ppb Hg = 1 ng Hg per1 g water)
