Answer:
Option B will require a shorter wave length of light.
Explanation:
The bonding between Ozone (O3) and Oxygen (O2) can be used to explain why the breaking of oxygen into Oxygen radicals will require a shorter wave length.
- The bond between Oxygen (O2) is a double bond while Ozone (O3) has an intermediate bond between a double bond and a single bond.
- The bond order of Oxygen (O2) is equals 2 while that of Ozone (O3) is 1.5. Since the bond order of oxygen is higher, it will require more energy to break the bond compared to breaking the Ozone (O3) bond.
- Recall that Energy is inversely proportional to wave length.
- So it will require a shorter wave length to break the Oxygen (O2) into its radicals.
Molecules move more slowly in solids because there they are all very compact
Indium has 49 protons
mass number (# of neutrons and # of protons combined) is 115
115 - 49 = 66
66 neutrons
Answer:
Rate expression has been given below
Explanation:
According to the given equation, 1 molecule of A reacts with 1 molecule of B and produces 2 molecules of B at a time.
So, rate of disappearance of both A and B are one half of rate of appearance of B
Hence rate expression can be represented as:
![Rate=\frac{-\Delta [A]}{\Delta t}=\frac{-\Delta [B]}{\Delta t}=\frac{1}{2}\frac{\Delta [C]}{\Delta t}](https://tex.z-dn.net/?f=Rate%3D%5Cfrac%7B-%5CDelta%20%5BA%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B-%5CDelta%20%5BB%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Cfrac%7B%5CDelta%20%5BC%5D%7D%7B%5CDelta%20t%7D)
where ![\frac{-\Delta [A]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B-%5CDelta%20%5BA%5D%7D%7B%5CDelta%20t%7D)
is rate of disappearance of A, ![\frac{-\Delta [B]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B-%5CDelta%20%5BB%5D%7D%7B%5CDelta%20t%7D)
is rate of disappearance of B and ![\frac{\Delta [C]}{\Delta t}](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20%5BC%5D%7D%7B%5CDelta%20t%7D)
rate of appearance of C
Answer:
Barium and Calcium
Explanation:
When heated with chlorine,
Both calcium and barium are able to form ionic bonds.
Hydrogen can only form bonds that are partial positive. It is not strong enough to be considered an ionic bond.
Silicon forms strong covalent with chlorine, called silicon tetrachloride. The structure is in diamond form which requires a lot of heat energy to break the bonds are way more than energy needed to break the bonds between calcium chloride.
Krypton is an inert element which does not form bonds with any elements under standard conditions
