Answer:Percent error= 90.9%
Explanation:
Percent error or percentage error is defined as the percentage of the difference between a measured value usually from an experiment and an exact value in comparison to the exact number.
its formula is thus
Percent error = experimental value - exact or actual value /exact value x 100
=(18.9 - 9.9 /9.9 ) x 100= 9/9.9) x 100
0.909 x 100 = 90.90 = 90.9%
Answer:
D. Oxidation
Explanation:
In an <em>electrolytic cell</em>, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.
A mnemonic technique that could be used is that the process that starts with a vowel (Oxidation) takes place at the place that also starts with a vowel (Anode).
