4.3 Reaction Stoichiometry
4.3 Reaction Stoichiometry
- The equation is balanced after a final check of atom and charge balance.
- H2O is produced by hydrogen peroxide in acidic solution.
- A balanced equation is needed for this reaction.
- By the end of this section, you will be able to: Chemical formulas give the identities of the reactants and products involved in the chemical change.
- A quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction can be made using coefficients.
- The use of balanced chemical equations is explored in this module.
- The way people go about many activities is similar to the way the general approach is used.
- Food preparation can offer an appropriate comparison.
- A recipe for eight pancakes calls for 1 cup pancake mix, 34 cup milk, and one egg.
- If two dozen pancakes are needed for a big family breakfast, the ingredient amounts must be increased proportionally according to the recipe.
- Balanced chemical equations are used to determine the amount of one reactant required to react with a given amount of another reactant, or to yield a given amount.
- The number of ammonia molecule produced from a given number of hydrogen molecule or the number of hydrogen molecule required to produce a given number of ammonia molecule can be calculated using these factors.
- Similar factors can be derived for any pair of substances.
- There is a reaction to produce aluminum iodide.
- The heat of the reaction causes some of the solid iodine to be purple.
- The two substances of interest are 3 mol I2 2 mol Al.
- The approach is the same, though the number of moles of the molecule is not requested.
- The moles-to-numbers conversion factor will be used.
- The amount of substances involved in a chemical reaction may be related to these examples.
- It's not easy to directly measure the numbers of atoms and molecules, and the more readily measured property of mass is required in the practical application of stoichiometry.
- Additional steps of the sort learned in the previous chapter are required in this case.
- The approach required here is the same as for the different approach only that the provided and requested mass are for reactant species.
- These examples show a few instances of calculation.
- Depending on what quantities are provided and sought, there are many variations on the beginning and ending computational steps.
- Regardless of the details, all of these calculations share a common essential component.
- Computational steps are depicted in the flowchart.
- Since the 1990s, most automobiles have safety features such as absorbers.
- When a vehicle is involved in a collision, an appropriate amount of gas needs to be quickly inflated to the correct level.
- The requirement is satisfied through the use of explosives and the decomposition of NaN3 is a common choice.
