is a reducing agent, 
is an oxidizing agent.
<h3>What is an oxidizing agent?</h3>
An oxidizing agent is a substance that causes oxidation by accepting electrons.
Al is a reducing agent, is an oxidizing agent.

Answer:
[H⁺] = 1.30X10⁻⁴ M
Explanation:
the problem will be solved by using Nernst's equation, which is :
In the given equation
n = 2
Q = ![=\frac{[Zn^{+2}][p_{H2}]}{[H^{+}]^{2}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5BZn%5E%7B%2B2%7D%5D%5Bp_%7BH2%7D%5D%7D%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D)
Putting values
![0.53= 0.76 - \frac{0.0592}{n}log(\frac{1X1}{[H^{+}]^{2}})](https://tex.z-dn.net/?f=0.53%3D%200.76%20-%20%5Cfrac%7B0.0592%7D%7Bn%7Dlog%28%5Cfrac%7B1X1%7D%7B%5BH%5E%7B%2B%7D%5D%5E%7B2%7D%7D%29)
on calculating
[H⁺] = 1.30X10⁻⁴ M
the answer is aaaaaaaaaaaaaaaaaaaaaaa
Answer:
Mass = 10.1 g
Explanation:
Given data:
Mass of Fe₂O₃ produced = ?
Mass of iron rust = 12.0 g
Solution:
Chemical equation:
4Fe + 3O₂ → 2Fe₂O₃
Number of moles of iron:
Number of moles = mass/ molar mass
Number of moles = 12.0 g/ 55.85 g/mol
Number of moles = 0.215 mol
Now we will compare the moles of iron and Fe₂O₃ .
Fe : Fe₂O₃
4 : 2
0.215 : 2/4×0.125 = 0.063 mol
Mass of Fe₂O₃ :
Mass = number of moles × molar mass
Mass = 0.063 mol × 159.7 g/mol
Mass = 10.1 g
