Discussion Overview

The discussion revolves around troubleshooting and balancing a chemical equation involving magnesium hydroxide and ammonium phosphate. Participants explore various strategies for balancing the equation and correcting any potential errors in the formulas presented.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant expresses uncertainty about balancing the equation and suggests there may be a typo in their formula.
  • Another participant points out that the reaction is unbalanced, specifically noting discrepancies in the number of oxygen and magnesium atoms.
  • A different participant proposes a balanced equation and outlines their method for balancing the atoms in a specific order: phosphorus, nitrogen, magnesium, oxygen, and hydrogen.
  • Another participant agrees with the balancing strategy and emphasizes the importance of balancing atoms that appear in only one molecule on each side of the equation.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the original equation's correctness, as some point out errors while others propose balanced versions. The discussion reflects multiple competing views on the balancing process.

Contextual Notes

Participants highlight specific atom counts and balancing strategies, but there are unresolved questions regarding the initial formula's accuracy and the steps taken to achieve balance.

Who May Find This Useful

This discussion may be useful for students or individuals interested in chemistry, particularly those looking to understand the process of balancing chemical equations and troubleshooting common errors.

I'm having trouble balancing this equation. I'm positive I've written the formula out correctly. Maybe there is a typo somewhere...

The question is:

magnesium hydroxide(aq) + ammonium phosphate(aq) --> magnesium phosphate(c) + ammonia(g) + water(l)

This is the formula I wrote out as:

MgOH(2) + (NH(4))3PO(4) --> Mg(3)(PO(4))2 + NH(3) + H(2)O

Any ideas or suggestions? Thanks

Your reaction is not balanced, look at the numner of oxygen atoms you have before and after the reaction.. neogenesis? :P

O: 14 to 9
check out your other atoms and figure out what is wrong with the equation.

Mg for instance, before the reaction you have got one molecule, after you magically have 3?
 
Ok based on the equation you gave, I think I got her.

3Mg(OH)2 + 2(NH4)3PO4 ---> Mg3(PO4)2 + 6NH3 + 6H20

I balanced it in this order:
1. balance P
2. balance N
3. balance Mg
4. balance O
5. balance H
 
I think a good stragegy might be balancing the atoms first, which are present only in one molecule at each side of the arrow.

So Shawn, your example is good since H was balanced last, O one before the last. That is good thinking.
 
3Mg(OH)2 + 2(NH4)3PO4 ---> Mg3(PO4)2 + 6NH3 + 6H20

3Mg(OH)_2 + 2(NH_4)_3PO_4 \longrightarrow Mg_3(PO_4)_2 + 6NH_3 + 6H_2O
