Compounded Problems
Compounds made of only two elements
What are Binary compounds?
Compounds formed when atoms share electrons in covalent bonds and usually formed between nonmetals.
What are Molecular Compounds?
A chemical reaction in which two or more substances react to form a single compound.
What is a Synthesis reaction?
All chemical reactions involve this.
What is energy?
These speed up reactions but are not changes in the process (they really aren't part of the chemical reaction).
What are catalysts?
A covalently bonded group of atoms that has a positive or negative charge and acts as a unit.
What are Polyatomic ions?
The SI unit for the amount of a substance.
What is a mole?
A chemical reaction in which a compound breaks down into two or more simpler substances.
What is Decomposition reaction?
Energy stored in chemical bonds.
What is Chemical energy?
In Endothermic reactions, reactants + energy equal this.
What are products?
Chemists use a system for naming compounds and writing formulas based on rules established by this organization.
What is the International Union of Pure and Applied Chemistry (IUPAC)?
A molecular compound with the formula: CO
What is Carbon Monoxide?
A chemical reaction in which one element takes the place of another element in a compound.
What is a Single replacement reaction?
The energy required to start a reaction.
What is activation energy?
In Exothermic reactions, products + energy equal this.
What are reactants?
When the name of the cation contains a Roman numeral to indicate the charge of the ion.
When does a metal form more than one cation?
A molecular compound with he formula: CO2.
What is Carbon Dioxide?
A chemical reaction in which two compounds exchange positive ions and form new compounds.
What is a Double replacement reaction?
A measure of how strong a bond is.
What is bond energy?
A chemical reaction that absorbs energy from its surroundings.
What is an Endothermic reaction?
The only cation on the Polyatomic Ions list.
What is ammonium ion?
6.02 x 10^23
What is Avogadro’s Number?
A chemical reaction in which a substance reacts rapidly with oxygen, often producing heat and light.
What is a Combustion reaction?
The principle that states, "energy cannot be created or destroyed, it can only be transformed from one type to another."
What is The Law of Conservation of Energy?
A chemical reaction that releases energy to its surroundings.
What is an Exothermic reaction?
