Mixtures
Explanation:
The forms of matter that exists without having chemical bonds between them are mixtures.
Mixtures are impure substances. They are made of matter that are not chemically bonded to one another.
Here are some of the characteristics of a mixture:
- Composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass
- The constituents retain their identities i.e physical properties are not altered.
- The constituents reacts differently to changed conditions.
- They can easily be separated into constituents by physical methods.
Many natural mixtures exists and several others can be formulated. Examples include air, sea-water, muddy water, alloys e.t.c

Answer:
The answer to your question is: 55.84 u. The element is Iron
Explanation:
isotope 1 mass 53.94 u abundance 5.85%
2 mass 55.9349 abundance 91.75%
3 mass 56.9354 abundance 2.12%
4 mass 57.9333 abundance 0.28%
average atomic mass = (53.94 x 0.0585) + (55.9349 x 0.9175) + (56.9354 x 0.0212) + (57.9333 x 0.0028)
average atomic mass = 3.155 + 51.32 + 1.207 + 0.1622
average atomic mass = 55.84 u. The element is Iron
Molar Mass of KCLO3
= 39 + 35.5 + 48 g
= 122.5 g .
So , percentage of Potassium ( K )
= 39 / 122.5 * 100 %
= 31.83 %
Now , percentage of Chlorine ( Cl )
= 35.5 / 122.5 * 100 %
= 28.97 %
So, finally, percentage of Oxygen ( O )
= 48 / 122.5 * 100 %
= 39.18 %
The ammonia gas is absorbed in the concentrated brine to produce aqueous sodium chloride and aqueous ammonia. This ammoniation process is exothermic, so energy is released as heat. The ammonia tower eventually needs to be cooled.
