Question

Arrange these species by their ability to act as an oxidizing agent. Best oxidizing agent Best reducing agent

Answer 1

1. Oxidising agent capacity : Au​​​^{​​​​​3+} > Sn^{​​​​​2+} > Fe^{​​​​2+} > Ca^​​​2+

Order of reducing nature : Ca​​​^{​​​​​2+} > Fe^{​​​​​2+} > Sn^{​​​​​2+} > Au^{​​​​​3+}

2. Metals reacting with acids to produce hydrogen gas are : Mg and Ca

3. H_{​​​​​​2}​​​​​O --> H_{​​​​​​2} + 1/2 O₂

4. 2Mg + O^{​​​​​​_{​​​​​​​}}​​​​​​_{​​​​​​2} --> 2MgO

5. C₇H_{​​​​16} + 11O₂ --> 7 CO_{​​​​​2} + 8 H₂O
