The mass of 40 mL of water is 40 grams. Since D = m/v and mL = cm3, the density of water is 1 g/cm3. Choose a volume between 1 and 100 mL. Use your graph to find the mass.

The cathode serves as the positive terminal and the anode as the negative terminal. The flow of electrons is from the cathode to the anode.</span><span>The relationship between a cathode and an anode involves electrons. An example of this is reaction that takes place in an electrolytic cell. It has a cathode compartment, an anode compartment and a salt bridge that divides the compartment. The movement of electrons is from the cathode to the anode. </span>
Answer: Option (b) is the correct answer.
Explanation:
A spontaneous reaction is defined as the process which tends to occur on its own. It does not require any external factor or force in order to start itself.
For example, when we dissolve KCl in water then potassium chloride being ionic in nature will dissolve on its own. Hence, it will be a spontaneous process.
And, a non-spontaneous reaction is defined as a process for the completion of which we have to provide certain conditions.
Thus, we can conclude that the statement it does not require any external action to begin, is true about a spontaneous process.
