Miscellaneous
Mass is neither created nor destroyed in a chemical reaction. The total mass of reactants equals the total mass of products.
What is The Conservation of Mass
Generally decreases across a period and increases down a group.
What is Atomic Radius?
Higher temperatures increase reaction rates by providing more energy to particles, leading to more frequent and energetic collisions.
What is Temperature's Effect on Reaction Rates?
A reaction with oxygen that produces energy (e.g., burning fuels).
What is Combustion?
If a system at equilibrium is subjected to a change in concentration, temperature, or pressure, the system will adjust to counteract that change.
What is Le Chatelier's Principle?
Increases across a period and decreases down a group.
What is Electronegativity?
Increasing the concentration of reactants increases the rate of reaction.
What is Concentration's Effect on Reaction Rates?
Two or more reactants combine to form a product (e.g., A + B -> AB).
What is Synthesis?
Water has a high specific heat, is a solvent for many substances, and expands when frozen.
What is the Unique Properties of Water?
Increases across a period and decreases down a group.
What is Ionization Energy?
More surface area allows for more collisions.
What is Surface Area's effect on reaction rates?
A single compound breaks down into two or more products (e.g., AB -> A + B).
What is Decomposition?
Water shapes landscapes through erosion, sediment transport, and weathering.
What is Water's Importance in Earth Processes?
Elements in Group 18 that are generally unreactive.
What is Noble Gases?
Substances that speed up reactions without being consumed.
What is Catalysts' effect on reaction rates?
An element replaces another in a compound (e.g., A + BC -> AC + B).
What is Single Displacement?
Characteristics that can be observed without changing the substance (e.g., color, boiling point, melting point).
What is Physical Properties?
What is answer every question?
Characteristics that describe a substance’s ability to change into different substances (e.g., reactivity, flammability).
What is Chemical Properties?
The ions of two compounds exchange places (e.g., AB + CD -> AD + CB).
What is Double Displacement?
