Answer:
0.017 mol
Explanation:
CH3COOH - acetic acid - we can write as C2O2H4
From formula C2O2H4 we can see that ratio C: O = 2:2 = 1:1, so number of moles C and O are the same.
So if we have 0.017 mol C, we should have 0.017 mol O.
Cd + 2HCl → CdCl₂ + H₂, 2ZnS + 3O₂ → 2ZnO + 2SO₂ and CH₄ + 2O₂ → CO₂ + 2H₂O reactions are redox reaction.
<h3>What is redox reaction?</h3>
Redox reactions are those reactions in which oxidation and reduction process takes place simultaneously.
Above balanced equation is a redox reaction as in this reaction oxidation of Cadmium takes place from 0 to+2 state and reduction of hydrogen takes place from +1 to 0 state.
- CuCl₂ + Na₂S → 2NaCl + CuS
- CaCO₃ → CaO + CO₂
Above two balanced reaction are not the redox reaction as their is no oxidation or reduction takes place.
Above balanced equation is a redox reaction as in this reaction oxidation of sulfur takes place from -2 to+4 state and reduction of oxygen takes place from 0 to -2 state.
Above balanced equation is a redox reaction as in this reaction oxidation of carbon takes place from -4 to+4 state and reduction of oxygen takes place from 0 to -2 state.
Hence, Cd + 2HCl → CdCl₂ + H₂, 2ZnS + 3O₂ → 2ZnO + 2SO₂ and CH₄ + 2O₂ → CO₂ + 2H₂O reactions are redox reaction

Answer:
A
Explanation:
You can eliminate C because you need to consult a periodic table to determine the mass (not the weight).
There are other answers you could use. The wording is awfully sloppy. D is an example of that. The elements part is true, the atoms part is not really true in all cases. For example NaCl is table salt and both the elements are ions, not atoms. Na is plus ion and Cl is minus one. B is wrong for the same reason.
I think in the end I would choose A. I think this is a very sly question. It is not really testing chemistry. It is testing how well you know your definitions.
Some athletes use anabolic steroids in order to make their performance better, but the side effects are destroyed testicles, bad vision, bad sleeping habits, bald head.
