Answer

Explanation:

Step1: Balance equation 1

Balance Li and H atoms. 2Li + H₂O₂ -> 2LiOH

Step2: Balance equation 2

Balance O atoms first. 2HgO -> 2Hg + O₂

Step3: Balance equation 3

Balance O atoms first. 2H₂O -> 2H₂ + O₂

Step4: Balance equation 4

Balance Si, F and H atoms. SiO₂ + 4HF -> SiF₄ + 2H₂O

Step5: Balance equation 5

Balance N and O atoms. 2N₂ + O₂ -> 2N₂O

Step6: Balance equation 6

Balance Mg and N atoms. 3Mg + N₂ -> Mg₃N₂

Step7: Balance equation 7

Balance Au, S and H atoms. Au₂S₃ + 3H₂ -> 2Au + 3H₂S

Step8: Balance equation 8

Balance Fe and O atoms. 4Fe + 3O₂ -> 2Fe₂O₃

Step9: Balance equation 9

As per tip, balance Cl first. H₃PO₄ + 5HCl -> PCl₅ + 4H₂O

Step10: Balance equation 10

Balance Al, Fe and O atoms. 2Al + 3FeO -> Al₂O₃ + 3Fe
