Answer:
6 elements which are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus
Explanation:
Living organisms are made up of various unit of giant organic molecules that have been produced through life processes.
The bulk of elements that makes up living organisms are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus.
Carbon is almost present everywhere in living organisms. It's unique ability to form a key component lies on its bond formation capabilities. Carbon is found in nearly all organic molecules like carbohydrates, proteins, fats and oils, e.t.c
Hydrogen like carbon is key to life. It is light and making it form different bond types with carbon. It is one of the atoms that makes up water.
Nitrogen is usually found in proteins. They are unique elements that life cannot do without.
Oxygen is useful in respiration processes and it is the bedrock through which energy is released from glucose.
Sulfur is key to life.
Phosphorus in Adenosine Diphosphate is a good store of energy.
The acronym 'DNA' stands for deoxyribonucleic acid.
DNA is used to 'code' the genetic makeup of all living organisms, and is found inside the nucleus of the cell(Eukaryotes) or just floating in the cytoplasm of the cell(Prokaryotes). DNA is made up of 4 different pairs of base molecules(nucleotides) that are slightly different from another. The similar molecule structure RNA(ribonucleic acid) differs from DNA in that RNA nucleotides are just slightly different from the nucleotides of DNA. This difference is that RNA nucleotides have a hydroxide group(OH) where the DNA nucleotides just have a hydrogen atom.
Because the DNA nucleotide doesn't have the hydroxide group it has one less oxygen than RNA nucleotides do. This is where DNA derives the prefix "deoxy-," meaning "without oxygen."
The prefix "ribo-" is given to molecules with a certain configuration of a set of 3 consecutive but not necessarily contiguous CHOH(asymmetric) groups.
The combined form "nucleo-" is used to imply something that has to do with the nucleus, such as the nucleus of a cell where DNA is stored in Eukaryotes.
And finally, the ending of the acronym: "acid." DNA is an acid because the 4 nucleotides each contain a phosphate group, which are acidic.
And thus, we get our answer: deoxyribonucleic acid, and the meaning:
deoxy-ribo-nucleic acid
(without oxygen) + (has 3 CHOH groups) + (in/of the nucleus) + (acidic)
Thus, DNA is a molecule is basically an acidic molecule residing in the nucleus with 3 CHOH groups and is missing oxygen atoms.
I know this isn't really what you're looking for, but honestly I had a great time doing a little research into the name!
Hope this explains it a little! c;
Answer:- 0.00724 moles.
Solution:- Grams of salicylic acid are given and it asks to calculate the moles.
For the moles, we divide the grams by the molar mass.
Formula of salicylic acid is 
Molar mass = 7(12.01)+6(1.01)+3(16.00)
= 84.07+6.06+48.00
= 138.13 gram per mol
We could make the dimensional analysis set up for showing unit cancellation and have the moles.
= 0.00724 moles
So, there will be 0.00724 moles of salicylic acid in it's 1.00 gram.
Answer:
Pyrophoricity is a property of metals and oxides of lower oxidation states, including radioactive ones, in which they spontaneously ignite during or after stabilization.
