Dihydrogen Monoxide Formula Stoichiometry Lab Question Problems?

Stoichiometry lab question problems? - dihydrogen monoxide formula

+ Zinc sulfate heptahydrate, sodium carbonate and respond to zinc sulfate and sodium phosphate to form carbon monoxide.

Write a balanced formula equation for the double displacement reaction. Predict which compounds will form a precipitate, and enter into the equation with the symbol (s) following the chemical formula

Here is a picture if it helps. That is what I have. I have balanced the equation.

So basically, I balanced the equation, but not part of the precipitate


Thank you!

great. You are in the middle.

The precipitate requires knowledge of the solubility. Basically, all the elements in Group 1 is always soluble, and does not form a precipitate. Therefore Na2SO4 Na + is excluded, not because it is a form of precipitation.

In addition, the water does not crash because it is part of the same liquid.

CO3 precipitation falls as ZnCO3 is not just a group of atoms, and some other elements.

Carbonate, the answer is ZnCO3 or zinc
