COMPOUNDS
What are binary compounds?
In this formula, these are the reactants:
H2 + O2 ---> H2O
What are hydrogen (H2) and oxygen (O2)?
This is the name for the energy required to start a reaction.
What is activation energy?
This is the measurement that helps chemists count atoms, molecules, or ions.
What are moles?
Fireworks are an example of this type of reaction.
What is exothermic?
This is what is indicated when an element ends in the suffix -ide.
Example: chloride, oxide
What is an anion?
This is a reaction in which 2 or more substances react to form a single compound.
What is synthesis?
Chemical bonds store energy- this is the name for that energy.
Energy is measured in these units.
This is the name for a reaction that absorbs energy from its surroundings.
What is an endothermic reaction?
When a cation contains a Roman numeral (like iron II), it indicates this.
What is the charge of the ion?
