Answer:
Explanation:
Hello,
In this case, considering the given information the redox reaction is:
Which properly balanced turns out:
In such a way, one sees a 6 to 1 molar relationship between the standard iron (II) solution and the dichromate, therefore, by using the following equation it is possible to determine the oxygen as shown below:
Thus, the moles of iron (II) solution are:
Moreover, the moles of dichormate result:
Thereby, the volume of the sample is:
Finally, the chemical oxygen demand result:
Best regards.

Answer: (C) 30 times
Richter scale is used to determine the magnitude of an earthquake from the arrival time of P and S waves. It determines the total amount of energy released during an earthquake.
If Richter magnitude scale measures 6.5 then it produces 30 times more energy than 1 Richter scale magnitude during an earthquake. The magnitude of an earthquake is plotted on a logarithmic scale from 1 to 9 and increases 10 folds by one magnitude. If 6.5 is the magnitude, it means it is 10 times more than 5.5 magnitude earthquake. Similarly the amount of energy is calculated as 30 folds. So 6.5 magnitude will have 30 folds more energy released than that with 5.5 magnitude earthquake.
