Answer:
The symbol is the right answer.
Explanation:
The “ Symbol” is the correct answer because chemist uses the letters of the alphabet to denote the element. For instance, the element oxygen is denoted by the letter of the alphabet “O”, the hydrogen is denoted by the letter of alphabet “H”, Boron is denoted by the letter of alphabet “B”, etc. Here these are the examples that use one letter but there are other elements that use more than 1 letter as the symbol. For example, the Chlorine is represented by the Cl.
Well, you didn't give me any options so if this isn't the answer to your pacific question then I apologize.
but most likely a steel smelting facility.
Hope this helps
Answer:
Explanation:
Oxidation no is equal to charge on each atomic ion. If it is increased , element is oxidised and if it is decreased , element is reduced .
2AgCl+Zn⟶2Ag+ZnCl2
Zinc is oxidised , Ag is reduced .
Ag⁺ converts to Ag . ( oxidation number is reduced ) so Ag is reduced.
Zn converts to Zn⁺² ( oxidation number is increased ) so Zn is oxidised .
4NH₃+3O₂⟶2N₂+6H₂O
oxidation number of nitrogen in ammonia is - 3
oxidation no of nitrogen in nitrogen is zero.
Oxidation no of nitrogen is increased so it is oxidised.
oxidation no of oxygen is zero in oxygen and its oxidation no in water is -2 . So oxidation no is reduced so oxidation is reduced.
Fe₂O₃+2Al⟶Al₂O₃+2Fe
oxidation no of Fe in Fe₂O₃ is + 3 and it is zero in Fe so iron is reduced.
oxidation no of Al in Al is zero and it is +3 in Al₂O₃ so it is oxidised .
Answer:
27.0
Explanation:
Because Mass can neither be created nor be destroyed hence total mass of sample of iodine and tube remain equal as it is sealed.
Answer: one simple distillation column is required to separate the stream into five pure products. With four different flat bottom flask, for collection of the distilled products
Explanation: simple distillation works with the difference in boiling points of the liquid to be separated. For the separation of five different constituent to be possible, we have to know the boiling points of the constituents.
For your understanding, let's define constituents in the liquid to be A, B, C, D, E. And the boiling points increases respectively. Start by heating the liquid to the boiling point of A to extract A. After a while check if the constituents A is still dropping in the flat bottom flask, if it has stopped dropping, it simply means that we have extracted all A constituents in the liquid, label the Flask A. Get another flask to extract constituent B.
Heat the mixture to the boiling point of B, after a while check if constituent B is still dropping in the flat bottom flask, if it has stopped dropping,it means that we have extracted all B constituent in the liquid, label the Flask B. Get another flask for C.
Repeat the same process for C and D.
After Extracting D we don't need to distillate E because we already have a pure form of E inside to the conical flask.
