4FeS2 + 11O2-> 2Fe2O3 + 8SO2
Not sure.... I think this is it
a) figure describe ionization energy , electron affinity & electron negativity
b) figure describe Atomic Radius
c) does represent anything
Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element. H-->Cl
Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy. M + IP-----> M+ + e-
Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.
X + e- ------> X- =- EA
Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.
Answer:They are all controlled by the human beings.
Explanation:
The selective breeding, cloning and genetic engineering are some of the techniques which is induced by the human efforts.
In case of selective breeding the male and female species having the selective characters are mated with each other so that the offspring produced has the desired characters. It neither requires any enzyme nor uses udder cells.
In case of genetic engineering, the gene of interest is inserted in the bacterial species by the help of vector so that when the bacterial species amplify the gene of interest. This is how the desired products are produced by bacterial species. Example: Insulin production.
Cloning can be defined as another technique made by human beings in which the genetically identical species is made naturally or artificially for the benefit of the mankind.
The element used to make the first atomic bomb is uranium
10) Arsenic is a chemical agent which was used in preserving dead bodies in the past. It is mainly a formaldehyde mixture with coloring agents to give a dead body the look of life. Sylvester was a third mummy that was embalmed with arsenic in the late 1800s and is now on exhibit at Ye Olde Curiosity Shop in Seattle, Washington. His mummified body showed an extremely unusual since the remains weighed approximately 80 lbs when a body is composed of 70-80% water, after dehydration, the weight should be about 20-30% the premortem weight. The solution was also used during Civil War to preserve dead bodies <span>as the dead were being shipped home from the battlefield.

9) R<span>esearch can yield dates when certain plants/animals became domesticated and entered the standard diets of people, meaning you would not see masses eating beef before the cow became domesticated. To further this you can look at when a specific food was introduced into the diets of people in the geographic area of the person you are studying. </span>
