Answer:
The particles start moving faster and expand making the ball expand.
Explanation:
Just try to find how you will get the reaction by adding the other reactions. Reverse the second eq as O is in reactant side and half it..
Now in the final reaction there is neither ozone nor oxygen so now you have oxygen on the products side after adding reversed
2 and 3, O ->1/2 O2
adding this to the third eq you get,
NO+O +O3 -> NO2 +3/2 O2
Now you need to remove O3 and O2 using the first equation,
So reverse the first one,half it and add, 3/2O2-> O3 adding it removes O3 and O2 you get the requires equation,
NO + O->NO2 you can do the calculation bit yourself when you add reactions Enthalpy is also added by Hess law so yeah that part should be pretty simple.
Calcium carbonate
Explanation:
The chemical most commonly used to counteract the effects of acid precipitation on aquatic ecosystems is calcium carbonate.
Acid rain or acid deposition or acid precipitation is any form of precipitation with an elevated level of hydrogen ion concentration in them.
To nullify this acidic precipitation in aquatic ecosystem, we need to use an environmentally friendly alkaline agent.
The most desired is calcium carbonate. The carbonate neutralizes the acid by producing carbon dioxide, water and calcium salts.
Answer:
(i) Formula = Fe₂(SO₄)₃
Name = Iron (III) Sulfate or ferric sulfate
(ii) Formula (NH₄)₂CO₃
Name = Ammonium Carbonate
Explanation:
Data given:
(i) Fe³⁺ and SO₄²⁻
ii) NH₄⁺ and CO₃²⁻
Formula and named of the compound =?
Solution:
(i) compound from Fe³⁺ and SO₄²⁻ and its name
writing a formula in combined form
- The symbols of two ions written together that is FeSO₄
- The charges shown on each atom is its valency and it show its combining tendency so iron will combine with 3 sulfate ions and sulfate ion will combine with 2 iron ions
- When two ions combine their valencies should be write on the base of the alternate ions.
- that is 2 will be at the base of Fe and 3 will be at the base of SO₄ without charges
- So the combined formula and name will be
compound formula form from Fe³⁺ and SO₄²⁻ = Fe₂(SO₄)₃
Name of the compound = Iron (III) Sulfate or ferric sulfate
______
(ii) compound from NH₄⁺ and CO₃²⁻ and its name
writing a formula in combined form
- The symbols of two ions written together that is NH₄CO₃
- The charges shown on each atom is its valency and it show its combining tendency so NH₄⁺ will combine with 1 carbonate ion and carbonate ion will combine with two NH₄⁺ ions
- When two ions combine their valencies should be write on the base of the alternate ions 1 should not be written.
- 2 will be at the base of NH₄⁺ without charge
- So the combined formula and name will be
compound formula form from NH₄⁺ and CO₃²⁻ = (NH₄)₂CO₃
Name of the compound = Ammonium Carbonate
Result the solution is a basic because .. in there added a strong base.. naoh
