BCA Method
Note: This method isn't about being "easier" or more simple. Rather, it is about having a better conceptual understanding of the process of stoichiometry calculations.
BCA Tables: The Process
Step 1: Write the balanced equation. Step 2: Make sure you have moles for your starting value. (Convert
from grams to moles using the molar mass if needed.) Step 3: Insert the starting moles into the BCA Table and complete
the "B" Row. Step 4: Calculate the changes necessary based on the mole ratio of
the balanced equation. (Complete the "C" Row.) Step 5: Calculate the "A" Row. Step 6: Convert any values from the "A" Row into grams (if needed)
by using the molar mass.
Practice Problem
Dihydrogen sulfide gas, which smells like rotten eggs, burns in air to produce sulfur dioxide and water. How many moles of oxygen gas would be needed to completely burn 2.4 moles of hydrogen sulfide? How many moles of each product would be produced?
Step 1: Write the balanced equation.
