Missing question:
<span>(1) C2H5OH (3) C12H22O11
(2) C6H12O6 (4) CH3COOH.
Answer is: 4) CH</span>₃COOH, acetic acid.
In water, acetic acid dissociates on ions, so it can conduct electricity:
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
When we put
electrodes (cathode and anode) in acetic acid solution, positive and negative
ions migrate to electrodes.<span>
Negative acetate ions go to positive electrode
and gives electrons to electrode.
<span>Positive hydrogen ions go to negative electrode
and gain electrons.</span></span>
<span>The question says,'before applying the corkscrew, Lucas discovers a bit of mold on the cork of a bottle of Pinot Noir. Lucas should............. The correct option is B. The standard method of removing mold from wine cork is to dampen a clean napkin with water and use it to wipe the mold away from the cork. The cork should then be removed and the outside and the inside of the wine neck must be cleaned thoroughly as well.</span>
Answer:
The correct option is 1, since by changing the partial pressures the gas pressures change, the gases go from the zones of higher partial pressure to the zones of lower partial pressure, an example of this is the homeostasis of the human pulmonary alveolus in gas exchange with CO2 and O2.
Explanation:
In the first it increases, in the second the volume is maintained, and in the third reaction it decreases.
Answer:
Atoms
Explanation:
The molecular formula uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. :)
