Key Topics to Focus On 🔑
Following are the major focus and the key topics, that should be addressed for you to prepare well for the study.com Chemistry 111L: The Chemistry I with Lab exam. Now let’s discuss certain issues and analyze, which topics are usually included in the exam. Having understood the key ideas in these lessons will prepare you for more advanced topics.
- Chemical Reactions & Equations
|
Concept
|
Description
|
Example
|
|---|---|---|
|
Reactants & Products
|
The reactants are the materials that undergo the chemical reaction while the product is substances formed as the result of the chemical reaction.
|
A classic example is the formation of water: 2H₂ + O₂ → 2H₂O. Here, hydrogen (H₂) and oxygen (O₂) are the reactants, and water (H₂O) is the product.
|
|
Balancing Equations
|
According to the first principle of chemical change, the mass of the reactants should be equal to the mass of the products. In order to solve an equation one must alter coefficients and not the subscripts.
|
For instance, balancing the combustion of methane: CH₄ + 2O₂ → CO₂ + 2H₂O. This ensures the same number of atoms on both sides of the equation.
|
|
Percent Yield
|
Measures the efficiency of a reaction. Calculated using the formula: (Actual yield / Theoretical yield) × 100%.
|
If your experiment predicts 50 grams of product but you only get 40 grams, the percent yield is (40 / 50) × 100% = 80%.
|
Key Points:
- Pay special attention to balancing equations—this will be heavily tested in the final exam, and it’s a common pitfall for students.
- Understanding percent yield can also help in lab experiments, especially when calculating how efficient your reaction was compared to the theoretical maximum.
- Always remember: In every chemical reaction, mass is conserved!
- Gas Laws
|
Law
|
Description
|
Formula
|
|---|---|---|
|
Boyle's Law
|
The pressure and volume of a gas are inversely proportional at a constant temperature.
|
P₁V₁ = P₂V₂
|
|
Charles' Law
|
The volume of a gas is directly proportional to its temperature at constant pressure.
|
V₁ / T₁ = V₂ / T₂
|
|
Ideal Gas Law
|
Describes the relationship between pressure, volume, temperature, and number of moles.
|
PV = nRT (R = 0.0821 atm·L/mol·K)
|
Key Points:
- The Boyle’s, Charles’, and the Ideal Gas Law are the basis for understanding how gases act under different circumstances.
- You’ll likely see problems on the final exam where you need to rearrange these equations and solve for different variables like pressure (P), volume (V), or temperature (T).
- Don’t forget that temperature always needs to be in Kelvin when using these gas laws!
- Atomic Structure & Periodic Trends
|
Property
|
Explanation
|
Trend on the Periodic Table
|
|---|---|---|
|
Atomic Radius
|
Distance from the nucleus to the outermost electron shell. Increases down a group decrease across a period.
|
Elements like francium have a large atomic radius, while helium has a small atomic radius.
|
|
Electronegativity
|
The ability of an atom to attract electrons in a bond. Decreases down a group, and increases across a period.
|
Fluorine is the most electronegative element, making it highly reactive.
|
Key Points:
- Understanding these periodic trends will help to better predict how the atoms will interact with one another at different times.
- The influence of electronegativity is significant in deciding the nature of the bond formed and whether the bond is ionic, polar covalent, or non-polar covalent.
- This material will be covered in tests regarding bond formation, thus, identifying trends in these cases will be beneficial.
- Intermolecular Forces (IMFs)
|
IMF Type
|
Description
|
Real-World Example
|
|---|---|---|
|
London Dispersion Forces
|
The weakest force occurs between all molecules due to temporary dipoles.
|
Explains why nonpolar molecules like O₂ can condense into a liquid under cold temperatures.
|
|
Dipole-Dipole Forces
|
Occurs between polar molecules with permanent dipoles.
|
HCl exhibits dipole-dipole interactions due to the difference in electronegativity between hydrogen and chlorine.
|
|
Hydrogen Bonding
|
Stronger IMF occurs when hydrogen bonds with electronegative atoms like F, O, or N.
|
Responsible for water's high boiling point and surface tension. Think of water (H₂O) forming hydrogen bonds between molecules, which is why water is such a powerful solvent.
|
Key Points:
- IMFs are responsible for defining some of the physical characteristics of substances including the boiling and melting point.
- Hydrogen bonding is what makes water such an effective solvent, and you’ll need to know this for both the lab component and the final exam.
- Such questions will include forces affecting phase changes, hence, ensure that you are able to explain how IMFs determine whether a given substance is in the solid, liquid, or gaseous form.
Below is a list of major headings that, if you grasp them, will give you the knowledge base to succeed in the study.com Chemistry 111L: Chemistry I with Lab final exam!
