Fire transfers heat by CONVECTION, meaning some heat rises, and FALL, meaning some heat goes out in every directions.
Hope that helps!!!
Answer: Atoms with 11 protons, 10 neutrons and 11 electrons belong to the same element with 11 protons, 12 neutrons and 11 electrons.
Explanation:
Elements that contain same number of valence electrons belong to the same group. This is because they will have same reactivity (or properties) due to which they lie in the same group.
For example, element with 11 protons, 10 neutrons and 11 electrons is same as the element with 11 protons, 12 neutrons and 11 electrons.
Hence, both these atoms belong to the same element.
Thus, we can conclude that atoms with 11 protons, 10 neutrons and 11 electrons belong to the same element with 11 protons, 12 neutrons and 11 electrons.

Explanation:
Take 46g / 46 g/mol = 1 mol NO2 produced
1 mol * 1/2 = 0.5 mol O2 needed (1/2 ratio between NO2 and O2)
