Answer:
0.517
Explanation:
HCN + NaOH → NaCN + H2O [balanced as written]
(35.4 mL) x (0.268 M NaOH) x (1 mol HCN / 1 mol NaOH) / (18.35 mL HCN) = 0.517 M HCN
The best definition of energy is D. the ability to do work.
The others are examples of energy changes, but they are not definitions.
Non-spontaneous reaction occurs: electrolytic cell.
Spontaneous reaction occurs: voltaic cell
Oxidation occurs at anode: both
Electrolyte supports electron flow: both
