Lets write the formula, then start to determine!
Force = mass times acceleration
Therefore,
acceleration = force divided by mass
Answer:- A) mass
The cell notation of the redox reaction between Cu and ClO₃⁻ is:
<h3>What is a voltaic cell?</h3>
A voltaic cell or electrochemical cell is a device which produces electricity from chemical reactions occuring within the cell.
The reactions occuring in a voltaic cell are redox reactions.
Oxidation occurs at the anode while reduction occurs at the cathode.
In the given reaction between Cu and ClO₃⁻ as shown below:
- ClO₃⁻ (aq) + 3 Cu (s) + 6H⁺ (aq) → Cl⁻ (aq) + 3 Cu²⁺ (aq) + 3 H₂O (l)
Cu is oxidized as follows: 3 Cu (s) → 3 Cu²⁺
ClO₃⁻ is reduced as follows: ClO₃⁻ (aq) → Cl⁻ (aq)
The voltaic cell notation is as follows where Pt is used as an inert electrode in contact with the ClO₃⁻ and Cl⁻:
Therefore, the cell notation of the redox reaction between Cu and ClO₃⁻ shows that Cu is oxidized while ClO₃⁻ is reduced.

Answer:
Volume of the calcium hydroxide solution used is 0.0235 mL.
Explanation:
Moles of KHP =
According to reaction, 2 moles of KHP with 1 mole of calcium hydroxide , then 0.0330 moles of KHP will recat with ;
of calcium hydroxide
Molarity of the calcium hydroxide solution = 0.703 M
Volume of calcium hydroxide solution = V
Volume of the calcium hydroxide solution used is 0.0235 mL.
