The balanced equation for this is:
S8+ 802 =8S02
Hydrocarbons are a type of organic compound. Hydrocarbons contain a carbon, hydrogen and oxygen bond that makes it organic. Chlorides, carbonates, and nitrous oxides are not organic compounds but they are inorganic compounds.
It can be any row
Explanation:
An element with a valence electrons of 3 can be in any row on the periodic table.
The rows are the horizontal arrangement of elements on the periodic table.
Elements on the same row have the same energy level.
- The periodic table rows are called periods.
- It is only in the groups that we can find such element.
- Group 3 elements have 3 valence electrons.
- Since this group cuts through all the rows, therefore, elements with 3 valence electrons can be found in any row.

Explanation:
Exothermic reactions are those reactions in which heat is released.
Reactants→products+heat
For example, formation of ammonia from nitrogen and hydrogen is an exothermic reaction.
N2(g)+3H2(g)→2NH3(g)+92.2kJ
Endothermic reactions are those reactions in which heat is absorbed.
Reactants+heat→products
For example, dissociation of ammonia into nitrogen and hydrogen is an endothermic reaction.
2NH3 (g)+92.2kJ→
N2(g)+3H2(g)
