SUMMARY

The chemical equation Ag2S + HNO3 → Ag2SO4 + NO2 + H2O is correctly balanced using nitric acid (HNO3) instead of nitrous acid (HNO2). The oxidation and reduction processes must be identified, with silver compounds needing careful consideration. The balancing process involves counting elements on both sides, particularly focusing on oxygen to achieve equilibrium.

PREREQUISITES
  • Understanding of oxidation-reduction reactions
  • Familiarity with balancing chemical equations
  • Knowledge of silver compounds and their reactions
  • Basic chemistry concepts, including acids and their properties
NEXT STEPS
  • Study the principles of oxidation and reduction in redox reactions
  • Learn techniques for balancing complex chemical equations
  • Research the properties and reactions of silver sulfide (Ag2S)
  • Explore the differences between nitric acid (HNO3) and nitrous acid (HNO2)
USEFUL FOR

Chemistry students, educators, and anyone involved in chemical education or laboratory work will benefit from this discussion.

Ag(subscript of 2)S + HNO(subscript of 2) -> Ag(subs.2)SO(subs.4) + NO(subs.2) +H(subs2)O

TNX! PO!
 
Physics news on Phys.org
So, Ag2S + HNO2 -> Ag2SO4 + NO2 + H2O ?

What's being oxidised? What's being reduced? What stays the same?
 
In the future, you'll want to ask homework questions under

There is probably a mistake on your products side. Instead of HNO2, it's probably HNO3, nitric acid. The equation cannot balance with HNO2.

To find your coefficients:

Count and mark the number of elements on each side of the reaction.
Looking at your oxygens should get you the solution quickly.

Wait, this kind of looks like a dehydration reaction. Make sure about your silver compounds too.

You mean reagents side, don't you?
 
Indeed I did, my apologies.
 
my given is correct . and we answer it in while we were on our class :)

So, what is the answer then?
