weeeeeb [17]

Answer:

Four abiotic forms of nitrogen cycle and its chemical formula

Ammonium – NH^{4+}

Ammonia – NH^3

Nitrite – NO^2

Nitrate – NO^3

Explanation:

Ammonium: In the nitrogen cycle ammonium is starting point that is present in soil and are converted to various forms by different process.

Ammonia: In the process of nitrogen fixation, the bacteria having nitrogenase enzymes reacts with the nitrogen as well as hydrogen and produces the ammonia, which is further converted to organic compounds.

Nitrite: The nitrosomonas bacteria present helps in conversion of nitrogen gas into nitrite.

Nitrate: Again the Nitrite is converted into Nitrate by the nitrobacter. During the process of assimilation ammonium and nitrate are absorbed by the plants.

"ucture and properties of Matter
lapo4ka [179]

Answer:

Covalent bonds form when two atoms share valence electrons,

while Van der Waals forces cause an attraction between nonpolar

molecules

Explanation:

A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.

Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).
