Based on your answer in part B, arrange the five elements in order of their reactivity. Drag the most reactive element to the to
p and the least reactive element to the bottom. Tiles magnesium iron copper zinc hydrogen
1 answer:
Answer: Order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Explanation: Reactivity of the elements is the tendency of the elements to loose or gain electrons with ease.
As, all the given elements are metals, so the metals which will loose electrons easily will be more reactive. To study the reactivity of metals, we use reactivity series.
The metals which are more reactive are placed on the top of the reactivity series and which are less reactive are placed at the bottom.
Hence, the order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Reactivity series is attached below.

Answer:
The hydrogen ion concentrations associated with these pH value 7.35 is
The hydrogen ion concentrations associated with these pH value 7.45 is .
Explanation:
To calculate the pH of the solution, we use the equation:
We are given:
1) pH = 7.35
Putting values in above equation, we get:
The hydrogen ion concentrations associated with these pH value 7.35 is
2) pH = 7.45
Putting values in above equation, we get:
The hydrogen ion concentrations associated with these pH value 7.45 is .
