Question

Help me guys...✌️✌️

Write 15 chemical reaction and balance them and find the oxidized and reduced element and also oxidizing and reducing agents.
First and the best answer will be Brainiest

Answer 1

Hint 1

\text {Al}(s)\rightarrow \text{Al}^{3+} (aq)+3e^-A, l, left parenthesis, s, right parenthesis, right arrow, A, l, start superscript, 3, plus, end superscript, left parenthesis, a, q, right parenthesis, plus, 3, e, start superscript, minus, end superscript

2\text {H}^+(aq) + 2e^- \rightarrow \text H_2(g)2, H, start superscript, plus, end superscript, left parenthesis, a, q, right parenthesis, plus, 2, e, start superscript, minus, end superscript, right arrow, H, start subscript, 2, end subscript, left parenthesis, g, right parenthesis

Hint 2

332266

6H+(aq)+6e−2Al(s)6H+(aq)+2Al(s)→                      3H2(g)   3×reduction half-reaction→2Al3+(aq)+6e−     2×oxidation half-reaction→2Al3+(aq)+3H2(g)         Overall balanced reaction
