Hydrophilic compounds polar or non polar?
Hydrophilic compounds are polar or ionic and this is the reason for attraction of water towards these substances.
Carbon dioxide contains carbon yet it is considered to be inorganic Why?
Organic compounds are actually compounds containing carbon covalently bonded with a hydrogen. You can say carbon is the main thing here. Compounds of carbon [except oxides, carbonates, bicarbonates] are termed as organic. Water does not contain a carbon atom. So it is inorganic. Carbon dioxide is considered by chemists as inorganic, along with carbon monoxide, carbonates and bicarbonates. Nature has not distinguished compounds into inorganic and organic compounds that clearly. These compounds of carbon are just assumed to be inorganic. Also there is that one thing about carbon being covalently bonded with hydrogen in organic compounds. Due to that criteria carbon dioxide is considered inorganic. But actually there is no clear reason.
One reason that carbon atoms form large numbers of compounds is that a carbon atom forms?
One reason that carbon atoms can form large numbers of compounds is that a carbon atom forms four bonds in its compounds.
What is the difference between an organic compound and an inorganic compound?
In general, if a compound contains carbon it is organic. The reason for this is that carbon is considered to be the building block of life, and inorganic compounds are said to be more mineral than biological. There are, however, a few cases of carbon-containing compounds which are considered inorganic because of convention, some being carbonates, simple oxides of carbon, cyanides and the allotropes of carbon.
What is the reason for coordination compounds to have various colors?
r u unistar ?
Why water dissloves so many different substances?
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
What is the reason for colour in chemical compounds?
because the ions involved are of specific colors.
What cause a depletion of the ozone?
There are some chemical compounds. Main reason is CFC
Is rotted food a physical or chemical change?
It is a chemical change since the bacteria chemically reacts with the food and forms other compounds which are not healthy for edification. There is a change in odor and sometimes even color. Another reason it is considered a chemical reaction is because it cannot be reversed back into the original fresh (not ruined) food.
What make a brass not a mineral?
For the same reason that substances like steel are not considered to be minerals. Brass is an alloy of other metals and has to be deliberately created. It's made of other metals, which are not actually minerals themselves either.
Is a leaves a sample of matter what is the reason?
Leaves are complex mixtures of many compounds; all these compounds are formed from atoms. And atoms are the smallest units of matter.
Are the reactants of photosynthesis organic or inorganic?
I think what you're asking is, are the materials autotrophic eukaryotes (multicellular organisms that are able to produce their own glucose for energy), like most plants that use photosynthesis to produce glucose from carbon dioxide and water, considered inorganic compounds? sunlight H20+CO2---------> C6H12O6 + O2 the best answer I found was, "Organic compounds are actually compounds containing carbon covalently bonded with a hydrogen. You can say carbon is the main thing here. Compounds of carbon [except oxides, carbonates, bicarbonates] are termed as organic. Water does not contain a carbon atom. So it is inorganic. Carbon dioxide is considered by chemists as inorganic, along with carbon monoxide, carbonates and bicarbonates.
