1. Stoichiometry Basics
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It is essential for understanding the behavior of chemical systems and for predicting the outcomes of reactions. Stoichiometric calculations involve using the mole concept, which is a measure of the amount of substance.
Stoichiometry plays a crucial role in various fields, including:
- Chemistry
- Medicine
- Environmental science
2. Balancing Chemical Equations
A balanced chemical equation shows the stoichiometric ratios of the reactants and products in a chemical reaction. Balancing equations ensures that the number of atoms of each element is the same on both sides of the equation.
To balance equations, follow these steps:
- Write the unbalanced equation.
- Count the number of atoms of each element on both sides.
- Adjust the coefficients in front of each molecule to make the number of atoms of each element equal on both sides.
3. Limiting Reactants and Excess Reactants, Chapter 11 stoichiometry answer key
In a chemical reaction, the limiting reactant is the reactant that is completely consumed, while the excess reactant is the reactant that is left over after the reaction is complete.
To determine the limiting reactant:
- Convert the given amounts of reactants to moles.
- Use the stoichiometry of the balanced equation to determine the mole ratio between the reactants.
- Compare the mole ratios to the actual mole amounts.
