  • OMG!WE HAVE A HOMEWORK in Chemistry AND THE DEADLINE IS TOMORROW
  • And it is about... writing and balancing the chemical equations
  • No need to worry Gen, because there are 3 easy ways to solve that homework
  • Homework:
  • write and balance the chemical equation
  • " Nitrogen gas reacts to Hydrogen gas to produce Ammonia"
  • STEP 1: Convert the given problem into a word equation.
  • Nitrogen gas + Hydrogen gas --> Ammonia
  • N + H --> NH 2(g) 2(g) 3(g)
  • STEP 2: Convert the word equation into a chemical equation.
  • Note that there is a subscript written after the chemical symbol of Nitrogen at the reactant side of the equation is 2 while the hydrogen is 2 as well. This is because of both nitrogen gas and hydrogen gas are diatomic substance. Carbon, Hydrogen, Oxygen, Nitrogen, and other elements are diatomic substance. The product side, the chemical formula of ammonia is NH3. 
  • N + 3H --> 2NH 2(g) 2(g) 3(g)
  • STEP 3: Balance the given chemical equation written inthe step 2 by adding coefficient after the chemical symbol or chemical formula.
  • To explain how we came up with this balanced chemical equation, let us refer the chemical equation in step 2. Let us determine the number of atoms of each element in the reactant side and in the product side. Look at the diagram below showing the subscript written after the chemical symbols and chemical formula in the chemical equation. Carbon, Hydrogen, Oxygen, Nitrogen,
