chemical reactions Flashcards
precipitate
a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid
product
a substance that is formed as a result of a chemical reaction.
reactant
a substance that is used in a chemical reaction to create new products.
diatomic element
an element that cannot stand alone
Hydrogen (H₂)
Nitrogen (N₂)
Oxygen (O₂)
Fluorine (F₂)
Chlorine (Cl₂)
Bromine (Br₂)
Iodine (I₂)
soluble
refers to a substance that can dissolve in a liquid, forming a solution.
Law of Conservation of matter
matter cannot be created or destroyed in a chemical reaction. It can only be rearranged or transformed from one form to another.
insoluble
a substance that does not dissolve in a liquid.
activity series
a list of metals arranged in order of their ability to displace other metals from compounds in a chemical reaction.
aqueous
dissolved in water
solubility rules chart
indicates which common ionic compounds are generally soluble or insoluble in water:
(s)
Solid: The substance is in the solid state.
(aq)
Aqueous: The substance is dissolved in water, forming a solution.
(l)
Liquid: The substance is in the liquid state.
∆
Heat: Indicates that heat is required or applied during the reaction.
(g)
Gas: The substance is in the gaseous state.
