Loss of atmospheric ozone has led to an ozone "hole" over Antarctica. The process occurs in part by three consecutive reactions. (Each of the reactants and products in these reactions are gases.)
(1) Chlorine atoms react with ozone (O3) to form chlorine monoxide and molecular oxygen.
(2) Chlorine monoxide forms ClOOCl.
(3) ClOOCl absorbs sunlight and breaks into chlorine atoms and molecular oxygen. If the coefficient for a particular substance is "1", do not write the "1" in the balanced equation. For example, instead of writing "1Cl(g)", simply write "Cl(g)".
(a) Write a balanced equation for each step, including the state of each molecule.
(b) Write an overall balanced equation for the sequence.
Ozone O₃ consists of a strong reactive gas made up of three atoms of oxygen. Ozone occurs on the Earth as natural and man-made gas.
Ozone impacts life on Earth in positive or harmful ways depending upon its location in the atmosphere.
From the information given, we are to balance the reactant and the product that leads to the formation of Ozone by following each step.
Step 1:
2Cl° + 2O₃ 2ClO° + 2O₂
Chlorine molecular
monooxide oxygen
Step 2:
2ClO° ClOOCl
Step 3:
ClOOCl + sunlight → 2Cl° + O₂
(b)
The Overall balanced equation can be expressed as:
2O₃ → 3O₂
Therefore, from the above explanation we can see the step by step process for the balanced equation and the overall balanced equation.

Explanation:
The chemical reaction represented as “AB ⇒ A + B” is a ______
Answer:
Below
Explanation:
This would be a decomposition reaction. This occurs when a compound breaks down into 2 + simpler substances. We can see this from AB --> A + B, one compound (AB) breaks down into 2 simple substances ( A and B ).

The ionic radius of a sodium ion is 2.27 angstroms (A) . What is this length in um
[tex]\boxed{\sf 1Å=10^{-10}m}[/tex]
[tex]\\ \rm\longmapsto 2.27Å[/tex]
[tex]\\ \rm\longmapsto 2.27\times 10^{-10}m[/tex]
[tex]\\ \rm\longmapsto 0.227\times 10^{-9}m[/tex]
[tex]\\ \rm\longmapsto 0.0227\times 10^{-8}m[/tex]
[tex]\\ \rm\longmapsto 0.00227\times 10^{-7}m[/tex]
[tex]\\ \rm\longmapsto 0.00023\times 10^{-6}m[/tex]
[tex]\\ \rm\longmapsto 0.00023\mu m[/tex]
Therefore, length = 2.27 × [tex]10^{-4}[/tex] um
Ionic radius of sodium = 2.27 angstrons
1 angstron = [tex]10^{-10} m[/tex]
1 m =[tex] 10^6[/tex] micrometer (um)
So, 1 angstron = [tex]10^{-10} m\times10^6 um/m = 10^{-4} um[/tex]
Hence,
2.27 anstrons × [tex]10^{-4}[/tex] um/angstron =
2.27 ×[tex] 10^{-4} [/tex]um
So, length = 2.27 × [tex]10^{-4}[/tex] um

Answer:

What is the final temperature of water given an initial temperature of 28 ˚C, a mass of 7 g, and heat (q) of 184 J (Specific Heat of water = 4.184 )?
Answer:34.28 Degree celcius
Explanation:The heat given is equal to the change in temperature multiplied by the mass and the specific heat capacity
This gives the equation:Q=mc∆T
Where Q=184,m=7, specific heat capacity=4.184,∆T=X-28,
But ∆T=Final temperature (T'')-Initial temperature (T')
Therefore the equation becomes
184=7×4.184(X-28)
Solving the remaining linear equation gives you X as 34.28°C

Filtration is the most appropriate method for separating a solution of water and which substance?
A. alcohol
B. salt
C. sand
D. sugar
Answer:
Sand
Explanation:
If you get salt or sugar in your water, you have to legit desalinate it to get the water and item out. You need to evaporate the water by increasing temperature and then lower temperature to separate the substances.
If you have alcohol, you need to distill it by trapping it and stuff.
With sand, the molecules are much larger which lets you separate the substances easily.
For example, on a beach, you can slap a handful of sand in your pail, but the sand sinks to the bottom right? You can just pour out the water.
What is a mixture? How will you separate the components of a mixture containing sugar, sand and water?
Answer:
Mixture is combination of two or more substances
Explanation:
The sugar would dissolve in water. You could then pour off the solution and wash the remaining sand with a bit more water. Heat the water to evaporate it from the sugar, and the two are separated.

Balance this equations pH3+O2=P4O10+H2O
Because there are 4 P on the right side, we have to put a coefficient of 4 on the left to balance out the P.
This would give us 12 H on the left and 2 H on the right, so we have to put a 6 on the right to balance out the H.
Now we have 16 O on the left and 2 on the right, so a coefficient of 8 is required to balance out the O.
