Answer:
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
Explanation:
In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;
A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.
The answer is flow of heat
<span>Coca-cola is similar to tomato juice because both are acidic drinks. Coca-cola is acidic because it is a carbonated drink. This means there is a presence of an acid in coke namely: carbonic acid and phosphoric acid. Tomato juice is also acidic because of the presence of vitamin c (ascorbic acid), but slightly less acidic than coke.</span>
Answer:
Explanation:
1 mol of sodium = 23 grams (use the number on your periodic table).
0.7350 mol sodium = x
Cross multiply
1*x = 0.7350 * 23
x = 16.905
You will get slightly less than this, depending on your periodic table. But the method will be the same.
Answer:
The answer to your question is: D) 8
Explanation:
We can know the valence of an element if we know in which is located.
For example if an element is in group IA it would have 1 valence electron,
if an element is located in group IIIA it would have 3 valence electrons, if an element is located in group VIIA, it would have 7 valence electron and so on.
Neon is located in group VIIIA, so it would have 8 valence electrons.
