Chosen Problem on Chemical Reactions #1 Magnesium reacts with nitrogen gas to produce Magnesium nitride.
Hmm.. Ma'am Jovy is counting on me. How can I solve this again? Think, Mira, think!
Magnesium solid + Nitrogen gas --> Magnesium nitride
Step 1: Convert the given problem into a word equation
Magnesium solid + Nitrogen gas --> Magnesium nitride
Mg (s) + N2 (g) --> Mg3N2(s)
Step 2: Convert the word equation into a chemical equation whilst looking out for diatomic substances like nitrogen
Reactant SideElementProduct Side3 = (3)1Mg32N2
Oh I can totally remember now. By referring to Step 2, listing the coefficients of the reactant and product side can make you see a lot better!
In balancing the number of atoms , a coefficient is added before the chemical symbol as indicated in the parenthesis.
Final Balanced Equation
Omg. it now satisfies the law of conservation of matter!
3 Mg (s) + N2 (g) --> Mg3N2(s)
Step 3:Balance the given chemical equation written in the step 2 by adding coefficient afterthe chemical symbol or chemical formula.
THE END
