B is the answer to it!!!!!
Answer:
The only PH range which is not covered by any of the given components of the universal indicator is 7.6-8.0
Hence the PH range 7.6-8 can't be described using universal indicator.
Answer:
The coefficients would be 2, 3, 2, and 4.
Explanation:
If we want to check this we would multiply the coefficient by each element. What we want is to have the same number of atoms on each side.
<em><u>Reactant side:</u></em>
- # of carbon atoms: 2
- # of hydrogen atoms: 8
- # of oxygen atoms: 8
<em><u>Product side:</u></em>
- # of carbon atoms: 2
- # of hydrogen atoms: 8
- # of oxygen atoms: 8
And that's it!
