D, forms from decomposed material
Explanation:
C3H8 + 502 ----> 3CO2 + 4H20
4NH3+7O2------> 4NO2+6H2O
2Al(NO3)3 + 3Na2S -------> Al2S3+6NaNO3
Based on bond type, CaCI2 has the highest melting point.
It's called "Ionic compound"
This was clear chemical reaction. The Potassium Chlorate reacted with Oxygen in a combustion reaction to change the chemical structure so that it was able to react with Silver Nitrate.
