The species is; Ca(NO3)2 ( NO3(-) is a polyatomic ion and is in parenthesis )
7.5 grams Ca(NO3)2 (1 mole Ca(NO3)2/164.1 grams)(2 mole N/1 mole Ca(NO3)2)(6.022 X 10^23/1 mole N)
= 5.5 X 10^22 atoms of nitrogen
Nitrogen can be found and obtained from air. about 78.08% of the air we breathe is nitrogen...Nitrogen is a gas.It is dominant in atmosphere.
Nitrogen, making up 75% of the Earth's atmosphere.
75. decane 2-methylnonane 2,2-dimethyloctane 2,3-dimethyloctane etc. ... I'm not going to list all 75.
Each formula unit of Fe2(C2O4)3 contains 15 atoms (2 Fe atoms, 6 C atoms, and 7 O atoms). Therefore, 5 formula units would contain a total of 75 atoms (5 formula units x 15 atoms per formula unit).
Nitrogen is a common element on Earth and can be found in the atmosphere, making up about 78% of the air we breathe. It is also present in the soil, oceans, and living organisms like plants and animals.
Yes. About 75% of air is Nitrogen.
About 75%
air molecules are , nitrogen , oxygen, and carbon dioxide mosly nitrogen (75%)
nitrogen about 75 (probably 65-85%)

After 3 half-lives, half of the original sample would remain unchanged. After the 1st half-life: 300 unchanged atoms. After the 2nd half-life: 150 unchanged atoms. After the 3rd half-life: 75 unchanged atoms would remain.
Nitrogen. N2 About 75%
This refers to the diatomic elemental form of nitrogen, N2. It makes up 75% of the atmosphere.
Because air is composed of nitrogen (not 100% mind you) and when you exhale air, you also exhale nitrogen.
Nitrogen is an element, atomic number 7, so a total of 7 electrons. In its elemental form it is a diatomic gas N2 which is approx 75% of the air around us. It forms many compounds, such as ammonia, NH3
