Manong Juan and Manang Maria are hardworking farmers in the Province of Laguna. Both are aware that to produce ammonia, there is a need to react nitrogen and hydrogen gas. But they wondered, how much urea fertilizer can be manufactured from ammonia. How many moles of N2 are consumed to produce 3.00 mol NH3? N2 + 3H2 → 2NH3
A mole is the number of atoms in exactly 12g of the carbon-12 isotope. This is called Avogadro’s number and is given by the value_____.
Arrange the following steps in calculating stoichiometric problems. I. Convert moles of wanted substance to desired units. II. Convert units of a given substance to moles. III. Balance the equation. IV. Using the mole ratio, calculate the moles of substance yielded by the reaction.
Balance the given equation.
NH₃ + O₂ → NO₂ + H₂O
What is the stoichiometric coefficient for hydrogen gas H2? N2+ 3 H2 → 2NH3
Suppose you want to determine the mass (g) of NH3 that can form from 2.50 moles N2. The mole factors needed would be:
N2+ 3 H2 → 2 NH3
How many grams of O2 are needed to produce 0.400 moles of Fe2O3 in the following reaction?
4 Fe + 3 O2 → 2 Fe2O3
