Study Notes

Chemical Reactions and Solutions

Molarity is a unit of measure that quantifies the amount of a substance dissolved in a solution.
A solution is a homogeneous mixture of a solvent and a solute.
Molarity is defined as the number of moles of a dissolved substance (solute) per liter of solution.
One mole equals 6.022 x 10^23 particles (Avogadro's number).

Gas-Phase Solutions

Four variables are needed to define the physical state of a gas: temperature, pressure, volume, and the amount of gas (expressed as the number of moles).
The ideal gas law quantifies the relationships between these variables.
At standard temperature and pressure (STP), one mole of gas occupies 22.4 liters.

Hydrates

A hydrate is a compound that contains water molecules.
When a hydrate is heated, the hydrate loses its water and the substance that is left over is called the anhydrate.
To determine the empirical formula of a hydrate, the "n" (number of moles of water) must be determined.
Steps to find the "n" moles of water in the hydrate: measure the compound before and after heating, determine the mass of water removed, convert the mass of water to moles, convert the mass of anhydrate to moles, and find the water to anhydrate mole ratio.

Dissolution

Dissolution is the process of a solute dissolving into a solvent to form a homogeneous mixture called a solution.
Factors that affect the rate of dissolution include polarity, temperature, pressure, and surface area of the solute.
Polar solutes dissolve in polar solvents, while nonpolar solutes dissolve in nonpolar solvents.

Solubility Curve

A solubility curve is a pictorial representation of the solubility of a solute in a solvent.
The curve represents the solubility limits of a given mass of solute in grams at a specific temperature in degrees Celsius.

Salts

Salts are ionic compounds with a cation and an anion.
Salt solubility is the amount of salt that is able to dissolve in a specified quantity of water at a certain temperature.
When two solutions with dissolved salts are mixed, a double replacement reaction occurs.

Colligative Properties

Colligative properties are properties of solutions that only depend on the ratio of solute and solvent present in the solution.
The four colligative properties are: boiling point elevation, freezing point depression, vapor pressure, and osmotic pressure.

Synthesis and Decomposition Reactions

A synthesis reaction is a reaction in which two or more substances combine to form a new compound.
A decomposition reaction is a reaction in which a compound breaks down into simpler substances.

Acids and Bases

Acids and bases have been defined in different ways, including the Arrhenius, Bronsted-Lowry, and Lewis definitions.
An acid is a proton donor, while a base is a proton acceptor.
An amphoteric substance is a chemical that can act as either a proton donor or acceptor.

Acid-Base Reactions

An acid-base reaction involves the reaction between an acid and a base to form their respective conjugate acid and conjugate base.
There are four acid-base reaction conditions: strong acid, strong base; strong acid, weak base; weak acid, strong base; and weak acid, weak base.

Autoionization of Water

Water molecules can ionize other water molecules to form hydronium ions and hydroxide ions.
The equilibrium constant for the autoionization of water is called the Kw constant, and is 10^-14 at 25°C.

Coordination Compounds

A coordination compound is a compound in which a central positively charged metal ion is covalently bound to a ligand in at least two places.
The oxidation number refers to the positive charges that a metal ion will most stably have on its own, and it is determined based on its spot in the periodic table.
The coordination number refers to the number of atoms most stably bound to a metal ion, which must be determined experimentally.

Redox Reactions

An oxidizing agent is a compound that easily gains electrons, decreases in oxidation state, and gets reduced in a reaction.
A reducing agent is a compound that easily loses electrons, increases in oxidation state, and gets oxidized in a reaction.
Redox reactions require both reduction and oxidation to occur simultaneously.

Electrochemical Cells

An electrochemical cell involves electron flow and a chemical reaction.
There are two types of electrochemical cells: Galvanic or Voltaic and Electrolytic.
All electrochemical cells include two electrodes: an anode and a cathode.

Motion

Motion is a change in the position or direction of an object relative to another object or a frame of reference.
Motion can be measured using velocity, speed, and acceleration, both instantaneously and as an average.
Average velocity is a change in position, or displacement, divided by a change in time.
Instantaneous velocity is a position of an object divided by the time it reaches that position.Here are the study notes for the provided text:

Speed and Distance

Speed measures how fast an object is moving through a distance
Formula: Speed = Distance / Time (S = d / t)

Acceleration

Acceleration is the rate of change of velocity over time
Falling objects accelerate at a consistent rate: -9.8 m/s/s
Acceleration can be calculated using a velocity-time graph

Mechanics and Motion

Mechanics is the study of moving objects
Motion is defined as the movement of an object
Inertia is the tendency of an object to resist changes in its state of motion
Velocity is speed with direction
Objects change their state of motion when forces act upon them

Circular Motion

Circular motion occurs when an object moves in a circle at a constant speed
Velocity changes constantly in circular motion
Centripetal force and centripetal acceleration are required to maintain circular motion

Projectile Motion

Projectile motion is the path of an object launched into the air
Equations used to solve projectile motion problems include:

Mass is directly related to inertia
Weight is a force that depends on mass and gravity

Force and Newton's Laws

Forces can be either contact or non-contact
Force is a push or pull resulting from an interaction between objects
Newton's First Law: an object at rest stays at rest, an object in motion stays in motion, unless acted on by an external force
Net force determines the change in an object's state of motion

Newton's Laws (continued)

Newton's Second Law: force is equal to the rate of change of momentum

Forces can be drawn as vectors to visualize the interactions between objects

Friction and Buoyancy

Friction is a force that resists motion between two surfaces
Buoyancy is the upward force exerted by a fluid on an object
Archimedes' Principle: the buoyant force on an object is equal to the weight of fluid displaced by the object

Momentum

Momentum is the product of an object's mass and velocity
Conservation of momentum: the total momentum of a system remains constant before and after a collision### Energy Concepts

There are two types of energy: kinetic energy and potential energy.
Kinetic energy involves motion or velocity, and the equation for kinetic energy is .
Potential energy is stored energy, and objects that are stationary have potential energy.

Energy Transformation

Energy can be transformed from one form to another, but it cannot be created or destroyed.

Pulley Systems

There are four types of pulley systems: fixed, moveable, compound, and complex.
Each type of pulley system serves a distinct purpose in affecting the input force needed to lift or lower an object.
The law of conservation of energy applies in pulley systems, meaning energy is neither created nor destroyed.

Law of Conservation of Mechanical Energy

The law of conservation of mechanical energy states that, for a closed system free from dissipative forces, energy is conserved.
Mechanical energy can change forms, such as from potential energy to kinetic energy.

Four variables are needed to define the physical state of a gas: temperature, pressure, volume, and the amount of gas (expressed as the number of moles).
The ideal gas law quantifies the relationships between these variables.
At standard temperature and pressure (STP), one mole of gas occupies 22.4 liters.

Hydrates

A hydrate is a compound that contains water molecules.
When a hydrate is heated, the hydrate loses its water and the substance that is left over is called the anhydrate.
To determine the empirical formula of a hydrate, the "n" (number of moles of water) must be determined.
Steps to find the "n" moles of water in the hydrate: measure the compound before and after heating, determine the mass of water removed, convert the mass of water to moles, convert the mass of anhydrate to moles, and find the water to anhydrate mole ratio.

Dissolution

Dissolution is the process of a solute dissolving into a solvent to form a homogeneous mixture called a solution.
