Answer:
The d-block elements are all metals and most have one or more chemically active d-orbital electrons. Because there is a relatively small difference in the energy of the different d-orbital electrons, the number of electrons participating in chemical bonding can vary.
C.) Volume
Intensive properties, for example; color and density, do not depend on present matter.
Human activities are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, theexhaust<span> from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.</span>
Answer: Option (d) is the correct answer.
Explanation:
The given equations as as follows.
(slow)
Therefore, overall reaction equation will be as follows.
So, cancelling the spectator ions then the equation will be as follows.
As, it is known that slow step of a reaction is the rate determining step. Therefore, rate law for the slow step will be as follows.
Rate law = ![k[H_{2}O_{2}][I^{-}]](https://tex.z-dn.net/?f=k%5BH_%7B2%7DO_%7B2%7D%5D%5BI%5E%7B-%7D%5D)
Hence, the reaction is first order with respect to ![[I^{-}]](https://tex.z-dn.net/?f=%5BI%5E%7B-%7D%5D)
and it is also first order reaction with respect to ![[H_{2}O_{2}]](https://tex.z-dn.net/?f=%5BH_%7B2%7DO_%7B2%7D%5D)
.
Also, acts as a catalyst in the reaction.
Thus, we can conclude that the incorrect statement is 
is a catalyst.
PH value of 0.10 m of HBr, a strong acid.
When dissolved in water it gives H+ and Br-, so H+ is the concentration.
pH = - log H+) => pH = - log (0.10) = -(-1) = 1
HF and HC2H3O2 are weak acids. They both will have pH value greater than 1 as they ionize in solution.
