mix it with water and if it seperates from the water it is hydrophobic
Chemical formulas are used to represent chemical compounds. It shows the component elements of the compound. Also it shows the ratios of the component elements.
Hydrophobic describes molecules that are repelled by water. You can determine if a molecule is hydrophobic by looking at its structure - if it contains mostly nonpolar covalent bonds or hydrophobic functional groups (e.g. alkyl groups), it is likely to be hydrophobic. Additionally, hydrophobic molecules tend to aggregate together in water due to the hydrophobic effect.
It depends on the surface status of the silicon. Bare silicon surface without any chemical termination is 'hydrophobic'. But this is very unstable status and it is very easily oxidized forming native SiO2 layer in the air which is 'hydrophilic'. Chemical treatment to make silicon surface hydrogen terminated will make it hydrophobic; while surface with OH termination will make it hydrophilic.
Cysteine is considered hydrophilic in terms of its chemical properties.
Quartz is a component of granite that is not susceptible to chemical weathering. Quartz is a very durable mineral that can resist the chemical breakdown caused by exposure to elements like water and air.
Oil is hydrophobic because its chemical formula doesn't allow it to dissolve in water. In other words, it's "water hating".
it is a chemical component which gives bad odor
The main component of a lipid bilayer is phospholipids. They are composed of a hydrophobic tail region and a hydrophilic head region which allows them to form a double layer that makes up the cell membrane.
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
Phospholipid bilayer which consist of hydrophobic tail (repelled by water) and hydrophilic head (attracted to water).The other component are cholestrol.
Water
The main component is ethanol.
