Answer:
in physical science, an isolated system is either of the following:
1. a physical system so far removed from other systems that it does not interact with them.
2. a thermodynamic system enclosed by rigid immovable walls through which neither mass nor energy can pass.
Explanation:
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.
Oxygen is more <u>electronegative</u> than Hydrogen
So . . .
When the two form covalent bonds, oxygen pulls the electrons closer and farther from hydrogen
So . . .
The water molecule is <u>polar</u>, with oxygen more negative and hydrogen more positive.
So . . .
Since opposites attract, the more negative oxygens attract the more positive hydrogens of other water molecules, forming the <u>hydrogen bonds.</u>
Symbol Element Atomic Radius Electronegativity Ionization Energy
Ca Calcium 194 pm 1 57110 kJ/mol
Ba Barium 253 pm 0.89 3.6 x 10³ kJ/mol
As Arsenic 114 pm 2.18 12310 kJ/mol
Bi Bismuth 143 pm 2.02 8520 kJ/mol
Based on the above information.
The element with the largest radius is Ba.
The element with the highest electronegativity is As
The element with the hightest Ionization energy is Ca.
Answer:
ΔG° = ΔH° - TΔS°
ΔG° = 25.22-(201 )(0.08448)
ΔG° = 8.24 kJ/mol
