Answer: 1.41725 X 10^{24} atoms
Explanation:
One male of any gas containing no. of atoms![$=6.023\times10^{23}$](https://tex.z-dn.net/?f=%24%3D6.023%5Ctimes10%5E%7B23%7D%24)
2.5 moles of gas containing no. of atoms![$=2.5\times6.023\times10^{23}$$=15.0575\times10^{23}$](https://tex.z-dn.net/?f=%24%3D2.5%5Ctimes6.023%5Ctimes10%5E%7B23%7D%24%24%3D15.0575%5Ctimes10%5E%7B23%7D%24)
The given gas is triatomic gas. Hence
No. of atoms![$=3\times15.075\times10^{23}$](https://tex.z-dn.net/?f=%24%3D3%5Ctimes15.075%5Ctimes10%5E%7B23%7D%24)
![$=14.1725\times10^{23}$\\$=1.41725\times10^{24}$](https://tex.z-dn.net/?f=%24%3D14.1725%5Ctimes10%5E%7B23%7D%24%5C%5C%24%3D1.41725%5Ctimes10%5E%7B24%7D%24)
Answer:
Explanation:
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
During the digestion process, the first step would be mastication, lubrication with the saliva, and later on is being formed into a bolus. Bolus is the term used for food substance that is turned into small balls. When the bolus is formed, this is then pushed or moved to the stomach.
Answer: Magnesium Mg
Explanation:
Oxidization is the process by which a substance either gains oxygen or losses electrons.
The chemical reaction of the above is denoted by,
Mg(s) + 2HCl(aq) -----> MgCl2(aq) + H2(g)
Mg went from a 0 to a +2 state which would mean that it lost electrons.
It was therefore oxidized.
