Compounds are different from elements primarily because compounds are composed of one or two elements. In this case, when elements are combined to form a compound,the reaction incurs a chemical change which results to a product with different properties as its base elements.
Answer : The expression for reaction quotient will be :
![Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}](https://tex.z-dn.net/?f=Q_c%3D%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5D%7D%7B%5BAg%5E%7B%2B%7D%5D%5E2%7D)
Explanation :
Reaction quotient (Qc) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.
The given redox reaction is :
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
The expression for reaction quotient will be :
You would also need to know the mol of sodium. After knowing the mol, write down the reaction;
Na + H20 -> NaOH + H2
Use the mol ratio, to find the amount of mol of sodium hydroxide. (Remember to balance the equation first)
After you have the necessary variables, use the following formula:
mass of sodium hydroxide = mol of sodium hydroxide x molar mass (relative/formula mass of sodium hydroxide)
That is how you will find the mass of sodium hydroxide.
Your answer is B: The outer electron of Adam B has moved to a higher energy state
