<span>It generally does not mean that there is double the oxygen, but in this case there is double, because the subscript number tells how many atoms of that element are in a particle. In this case, there are two of the oxygen, hence the DI-oxide verbiage, and one of the carbon. When there is only one, it's MONOxide, to indicate only one atom.</span>
Answer:
B
Explanation:
reaction order is simply the sum of orders for each reactant.
Answer: Option (d) is the correct answer.
Explanation:
An oxidizing agent is a specie which accepts electrons and gets reduced in a chemical reaction.
In the given reaction,
Oxidation state of Al changes from 0 to +3, therefore, it is reducing agent. Whereas oxidation state of Br is changing from -2 to -3 this means Br is gaining electrons, therefore, it is an oxidizing agent.
Thus, we can conclude that the statement is the oxidizing agent because its oxidation number decreases.
