The answer to the question is the first opti.on.A
Answer:
Reductio is gain of electrons, while oxdation is loss. The oxidtion states of carbon in the reaction will show either of oxidation or reduction occurrence.

Explanation:
Electrons displacement is explained for each reaction below:
- +2 to +4 = loss of 2 more lectrons-------oxidation
- +4 throughout reaction----no exchange of electrons
- -4 to +4 = loss of 4 electrons-----oxidation
- 0 to -2 = gain of 2 electrons-----reduction
In flame tests salts<span> that are </span>dissolved in water<span> are evaporated using a </span>hot flame<span>. In the flame the </span>metal atoms<span> become excited and produce their characteristic spectrum of light. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
About 255.3 grams is the answer I believe. I just had a school work packet and had that question on it, and that is the answer that I had put on it I believe.
adding more of solid X will increase the heat of the solution by another few degrees
