When crystals of feso4 are strongly heated the residue obtained is?
The residue obtained from heating crystals of FeSO4 (iron(II) sulfate) is Fe2O3 (iron(III) oxide) and SO2 (sulfur dioxide) gases. This is because the heating process causes the iron(II) sulfate to decompose, releasing water vapor, sulfur dioxide gas, and leaving iron(III) oxide as a solid residue.
What happens when Al reacts with FeSo4?
