Answer: Option (A) is the correct answer.
Explanation:
A solution that contains ions is able to conduct electricity because ionic solutions are capable of conducting electricity as there are ions which can move from one place to another.
Thus, all the options show formation of ions except the equation .
Hence, the equation represents a solution that does not conduct electricity.
Answer:
For finding frequency, we need to first find the period of the graph.
The period of a sinusoidal graph is the time interval in which it repeats its pattern.
In the graph, we can see, after time, it repeats its pattern.
Hence the period of the graph is .
Now we need to find its frequency
The formula for frequency is
This is the answer

Answer:
9.6 mol
Explanation:
Start by writing out the balanced equation of the reaction.
2 +
⇒ 2
Here you will see 2 mol of hydrogen for every 1 mol of oxygen. Using this ratio, you can assume the amount of hydrogen will always be double that of oxygen. In this case, 4.8 * 2 = 9.6
