Temple University Stoichiometry Questions
Question Description
I’m working on a science multi-part question and need guidance to help me understand better.
Stoichiometry
Select Water at the top and make a single water molecule.
- How many of each reactant were used?
- What is the mole ratio (how many of each reactant and product are there)?
- Now write it as a chemical reaction:
Ca(OH)2 + 2 HCl?CaCl2 + 2 H2O
Max out how many water molecules that can be made without leftovers/excess.
- How many of each reactant were used?
- How many products were produced?
- What is the mol ratio (how many of each reactant and product are there)?
- Now express it as a chemical equation:
Now max out every reactant.
- How many products were made?
- How many and what were the leftovers/excess?
- What is the limiting reactant?
Enter the following under reactants on the left (Before Reaction): 6 H2 and 4 O2
- Fill in the number of products and leftovers under After Reaction in the table below.
Products: Leftovers:
H2O |
H2 |
O2 |
|
# |
- How many H2 and O2 molecules do you need to make exactly 4 water molecules with no leftovers? H2 _____ O2 _____
Select Ammonia and Make a single ammonia molecule.
- How many of each reactant were used?
- What is the mol ratio?
- Write it as a chemical equation:
Find the max amount of ammonia that can be produced without any leftovers.
- How many of each reactant are used?
- How many ammonia molecules are produced?
- What is the mol ratio (how many of each reactant and product are there)?
- Write it as a chemical equation:
Now max all of the reactants.
- How many ammonia molecules are produced?
- How many of each leftover are there?
- What is the limiting reactant in this reaction?
Enter the following under reactants on the left (Before Reaction): 5 N2 and 5 H2
- Fill in the number of products and leftovers under After Reaction in the table below.
Products: Leftovers:
NH3 |
N2 |
H2 |
