Is chemistry relevant only in the chemistry laboratory?
no, it's relevant in many situations. Doctors can't even become doctors without chemistry, it's also very important to make medicines. Chemistry is very important (also chemistry just rocks in general) :)
What are the important developments in the field of chemistry during the 15th century?
Scientific instruments Medicine Chemistry
How many valence electrons does CH3CO-OH have?
Through covalent bonding, the nitrogen atom will have 8 valence electrons, the hydrogen atoms will each have 2 valence electrons, and the chlorine atom will have 8 valence electrons.
Why Antoine Lavoisier contribution important?
Antoine Lavoisier is credited with the discovery of the of mass conservation. But Lavoisier had many other important contributions in chemistry.
Why is the Lewis dot diagram important?
Becouse it shows how many Valence electrons an atom has

The chemistry of life is centered on the chemistry of the element oxygen?
It is not base on Oxygen, it is based of Carbon. Why? A simple answer, is because Carbon can bond with many other compounds and elements since it has 4 valence electrons. Oxygen has 6 valence electrons.

What role do oxidation numbers play in a chemical formulas?
Oxidation numbers are very important in much of chemistry because many times atoms do lose or gain electrons. When this happens, they become ions.However, oxidation numbers are especially important when writing chemical formulas for ionic compounds.
Where might one find pictures of women famous for their work in chemistry?
There are many places where one might find pictures of women famous for their work in chemistry. One might find pictures of women famous for their work in chemistry at popular on the web sources such as Smithsonian Mag and PhotoBucket.
Why are ion important in chemistry?
Ion is a basic compound of many chemicals/processes
Why is chemistry important in the following areashealth?
Chemistry is important in the area of health because many of our bodies functions are, in essence, chemical reactions. Further, chemistry is useful in synthesizing drugs that help alleviate physical issues, and vaccines that help eliminate diseases.
Is chemistry important to your life?
Yes, it is very important to life, because it is used in the manufacture of plastics, fertilizers, fuel, food, etc. By studying chemistry, you can know many things about the human body and also about plant and animal life. Another important thing is that chemistry is used in the manufacture of cosmetics.
How many valence electrons are in a full outer shell?
8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons
What can you do in chemistry?
In chemistry you work with mixtures, compounds, chemicals, elements, and you learn about atoms. Chemistry is very important because it teaches you many things like how to separate a mixture. Checks mix is a mixture and water is a compound.
Why are electrons not included in the atomic mass of an element?
They usually are, in fact. However, the combined weight of the electrons in an element makes up less than 0.03%, which means any value that includes them has too many decimal values below 1 to be used in everyday simple chemistry, and overcomplicates basic chemistry (such as that in high schools).
