Good day class! Yesterday, we studied about the Conversion of Balanced Equations. Today, I will group you into four members and I will test your knowledge about our lesson by giving you some sample problems.
How many moles of ammonia are produced if 4.20 moles of hydrogen reacted with an excess nitrogen?N2+3H2 2NH3
N2 + 3H2 2NH3STEP 1.In the given chemical equation, there are; No. of Moles Substance
The first step in Converting Balanced Equation is to analyze the given equation.
3 H2 2 NH3
The second step in Converting Balanced Equation is to identify the problem.
STEP 2. Identify the problem. ? moles of NH3 : 4.20 moles of H2
The third step in Converting Balanced Equation is to identify the conversion factor based from the balanced equation.
STEP 3. Identify the conversion factor based from the balanced equation.2 mole of NH3 3 mole of H23 mole of H2 2 mole of NH3
The last step in Converting Balanced Equation is to multiply the given in the problem with the identified conversion factor.
STEP 4. Dimensional Analysis using the identified conversion factor.4.20 mole H2 x 2 mole NH3 3 mole H2 = 2. 80 mole NH3
