Both are oxidation reactions. Burning is just a lot faster than rusting.
Carbon has a tendency to form covalent bonds.

Hello!
The genetic material of all organisms which is made up of two twisted strands in a double helix is called DNA (DeoxyriboNucleic Acid)
DNA is the basis of all genetic information. It contains all instructions for the development and functioning of all living organisms and some viruses. The main function of DNA is the long-term storage of information to build other cell components like Proteins and RNA. It is composed of two strands with 4 possible bases which are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).
Have a nice day!
Answer:
66.2 % of O
Explanation:
Our compound is the lithium nitrite.
LiNO₂
This salt is ionic and can be dissociated: LiNO₂ → Li⁺ + NO₂⁻
We determine the molar mass:
molar mass of Li + 3 . molar mass of N + 6 . molar mass of O
6.94 g/mol + 3. 14 g/mol + 6 . 16 g/mol = 144.94 g/mol
The mass of oxygen contained in 1 mol of lithium nitrite is:
6 . 16 g/mol = 96 g
So the percentage of oxygen present is:
(96 g / 144.94 g) . 100 = 66.2 %
