Re: Mass Action Balancing
No,
Lithium is too innoble . It will not exist in aqueous environment. It will form LiOH.
Also H4SiO4 is not stable, it decompose to SiO2 and 2 H2O

Re: Ph not being interpreted as phenol group
Write down what YOU think and dont use these robot programs. They never work correctly. Its the same like online translation programs.

Re: HELP
Sodium is exchanged by copper nothing else. The hydroxide is only to keep alcaline pH.
Na2EDTA + Cu 2+ => CuEDTA + 2 Na+
PS: please use better headline, instead only HELP.

Re: magnesium carbonate reaction
No it isn't, it is like in mathematics 1/2 + 1/3
How do you calculate it?
The citric acid has 3 H+ and the magnesium is Mg 2+
Now you have to combine it.
It is magnesium citrate nothing else.

Re: Gold (V) thiosulfate
Never heard about this compound.
But this one is existing
https://pubchem.ncbi.nlm.nih.gov/compou ... hiosulfate
But calculation is molar mass of all oxygen divided by molar mass of the compound.
For example CO2: 32 g/mol/ 44 g/mol *100% = 72,73 %
