Answer: as copper has lower electrode potential value than hydrogen, it could be reduced by hydrogen.
Explanation: hydrogen has zero reduction potential while Cu has +0.34V and Al has -1.66 V .
SO in electrochemical series who has most negative or less reduction potential value tends to be a good reducing agent than the other.

Answer:
a) 6,7x10⁻⁴M/s
b) 8,0x10⁻⁴M/s
Explanation:
a) You can determine the average rate of descomposition calculating the ratio of change of concentration to change of time.
For the entire experiment:
t=0,00→ 0,0100M
t=10,00→0,0033M
= 6,7x10⁻⁴M/s
b) Between 2,00 and 4,00 seconds:
t=2,00→ 0,0071M
t=4,00→0,0055M
= 8,0x10⁻⁴M/s
I hope it helps!
<h3><u>Answer;</u></h3>
Coefficient
<h3><u>Explanation;</u></h3>
- Coefficients are the numbers in front of the chemical formulas.
- For example in 3H2O ,the three infront of the water molecule is called the coefficient.
- These numbers give two very important pieces of information about a chemical equation. The coefficients give the number of molecules (or atoms) involved in the reaction.
- Additionally, coefficient give the number of moles of each substance involved in the reaction.
Answer:
The difference between normal salt and acid salt is that acid salt is basically made up of strong acid and also including a weak base. However normal salt is practically made up of strong base or even a weak acid and also a weak base. Acid salt or in a more logical term known as acidic salt ionises into a type of form of H + ions which is more than OH- ions, which is in a water solution. But even than normal salt ionises into a form of eqaul number of H+ ions and OH- ions in this so called water solution.
