How Do I Solve Double Displacement Reactions for Chemistry Homework?

Click For Summary

Discussion Overview

The discussion revolves around solving double displacement reactions for a chemistry homework assignment. Participants are asked to complete and balance chemical equations, identify reactants and products, and determine if reactions occur or not. The scope includes conceptual understanding and practical application of chemical reactions.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses significant stress and confusion regarding their chemistry homework, specifically about balancing equations and identifying products.
  • Another participant asks for clarification on which part of the homework is causing difficulty, focusing on finding products or balancing equations.
  • A participant shares their attempts at balancing the equations and expresses uncertainty about the correctness of their answers.
  • Some participants suggest that the posted answers may have issues, particularly with the valencies in the equations.
  • There is a mention of forum rules regarding posting answers, indicating a need for adherence to community guidelines.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correctness of the answers provided. There are multiple viewpoints on the validity of the attempts, and some participants express uncertainty about specific reactions and products.

Contextual Notes

I am so stressed right now and am on the verge of a nervous breakdown. My chemistry homework is just really confusing and I need to pass this class, could someone please help me out? I need to hand this in tomorrow and I have already answered the questions myself but I feel like my answers are all wrong. I would appreciate it if someone could show me how to solve these so I know that when I hand this in tomorrow it won't bring my grade down even lower.

Complete and balance following equations: (find reactants and products)
1.Reactants: KOH+H2SO4
2.Reactants: FeS+HCl
3.Reactants: NaCl+H2SO4

If reaction occurs, list products. If no reaction occurs, state "no reaction":
1.Reaction: CaBr2+KOH
2.Reaction: Cu(OH)2+HC2H3O2
3.Reaction: FeS+2HCl
4.Reaction: Ca(NO3)2+2HClMy attemps: 1. H2SO4(aq) + 2KOH(aq) --> K2SO4(aq) + 2H2O(l)
2. FeS + 2HCl ------> FeCl2 + H2S
3. 2NaCl + H2SO4 = Na2SO4 + 2HCl(g)

1. CaBr2 + KOH = CaOH + KBr2
2. Cu(OH)2 + 2 HC2H3O2 = Cu(C2H3O2)2 + 2 H2O
3. ?
4. No reaction ?

Idk what it nmeans by listing products :/

Please post your answers - forum rules!
 
What part do you struggle with exactly? Part where you need to find the products? Or part where you need to balance the equation?

Both, but finding products in particular. I swear I'm not an airhead lol, I had a medical issues which caused me to miss school and now I'm so behind. :cry:

Sorry, I'm a new member so I wasn't aware of the rules. I just posted my attempts.

I'm not much of a chemist, but those look right to me.

I don't think so. See http://www.chemguide.co.uk/inorganic/group7/halideions.html.

A problem with the valencies?

The rest I leave to others.
