I believe the correct answer is combustion reaction. The reaction given above is the said type. It <span> always involve molecular oxygen O2. Anytime anything burns (in the usual sense), it is a </span>combustion reaction<span>. Hope this answers the question. Have a nice day.</span>
When an organic compound reacts with oxygen and results in the formation of water and carbon dioxide then this type of reaction is known as combustion reaction.
Therefore, when benzene reacts with oxygen and results in the formation of carbon dioxide and water then we can say that benzene has undergone combustion reaction.
B.They all have their valence electrons in the same type of subshell
Explanation:
The electron configurations of elements in the same group (column) of the periodic table have them in the same type of subshell.
But the subshells may be of different shells. Thus , the energies of them need not be the same.
For example , The Alkalai Metals are found in the first column of the periodic table Group IA. This set of elements all have valence electrons in only the '' orbital and because they are in the first column they all have configuration. i.e,
Lets say foxes hunt rabbits. If their are too many foxes then they will compete for the rabbits. The rabbits get outnumbered by the amount of foxes so the foxes kill all the rabbits and the rabbits could eventually go extinct.
5.4 - 4.21 answer should only have the the number of significant digits as the number in the equation with the least number of significant digits... in this case 5.4 is only two significant digits....so the answer should only have two significant digits
