Answer 1

To write the formulas of ionic compounds in the criss-cross method, we should be known every element and its symbols. And also we should have a basic understanding of each atom which constitutes the compound. Here are the chemical formulas: 

• Zinc Nitrate Zn (NO3)2 

• Calcium Carbonate CaCO3 

• Aluminum Hydroxide Al (OH)3 

• Ammonium Hydroxide NH4OH 

• Silver Nitrate AgNO3 

• Copper Carbonate CuCO3 

• Potassium Oxide K2O 

• Iron Sulphate FeSO4
