chemical reactions Flashcards
Reaction
something done, felt, or thought in response to a situation or event.
Observation
the action or process of closely observing or monitoring something or someone.
Solubility
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent.
Combination
a joining or merging of different parts or qualities in which the component elements are individually distinct.
Exchange
an act of giving one thing and receiving another (especially of the same kind) in return.
Thermal Decomposation
Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing decomposition.
Displacment
the action of moving something from its place or position.
Reactant
a substance that takes part in and undergoes change during a reaction.
Product
an article or substance that is manufactured or refined for sale
Spectator ions
A spectator ion is an ion that exists as a reactant and a product in a chemical equation. Spectator ions can, for example, be observed in the reaction of aqueous solutions of sodium carbonate and copper(II) sulfate but does not affect the equilibrium:
participate
be involved; take part.
Element
an essential or characteristic part of something abstract.
Ion
forming nouns denoting the action of a verb or an instance of this.
Atom
the smallest particle of a chemical element that can exist.
Proton
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron.
Electron
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
Neutron
a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
Solution
a means of solving a problem or dealing with a difficult situation.
Aqueous
of or containing water.
Activity series
The activity series is a useful guide for predicting the products of metal displacement reactions. For example, placing a strip of zinc metal in a copper(II) sulfate solution will produce metallic copper and zinc sulfate, since zinc is above copper on the series.
