The general formula for an aldehyde is: b) rcho
An aldehyde in chemistry is an organic compound that contains the following functional group: RCHO in which the carbon atom is attached with a double bond with the oxygen atom and with a single bond with the hydrogen atom.
The aldehyde compounds are very used in the manufacture of solvents, perfumes and resins

Lipids are hydrophobic; They would be insoluble, group together, and float to the top
Answer:
Electrons repel each other due to electrostatic force of attraction between both of them as a result prevent the electron from entering the nucleus preventing it from collapsing
To solve this question, we first need to know the mass of one mole of mercury. This can be done by checking the periodic table.
From the periodic table, we can see that:
molar mass of mercury = 200.59 grams/mole.
From the measurements, the chemist found that the participated amount of mercury is 0.02 moles.
We can simply determine the mass of 0.02 moles by doing cross multiplication as follows:
mass of 0.02 moles = (0.02 x 200.59) / 1 = 4.0118 grams
Rounding the answer to 2 significant digits, we get:
mass of 0.02 moles = 4.01 grams
