Question
What volumes of $\mathrm{H}_{2}(g)$ and $\mathrm{O}_{2}(g)$ at STP are produced from the electrolysis of water by a current of $2.50 \mathrm{~A}$ in $15.0 \mathrm{~min} ?$
Step 1
We know that current (I) = 2.50 A and time (t) = 15.0 min = 15.0 * 60 s. We can use the formula: q = I * t where q is the charge transferred during electrolysis. q = 2.50 A * (15.0 * 60 s) = 2250 C Now, we can find the number of moles of electrons (n) using Show more…
