Chemistry Chapter 9 Flashcards

Study Notes

Chemical reaction involves the rearrangement of atoms from reactants to form products.
Reactants are the starting substances in a reaction, while products are the resulting substances.

A chemical equation represents a reaction using chemical formulas to indicate reactants and products' identities and amounts.
Coefficients are numbers placed in front of reactants or products to balance the equation.

Synthesis reaction combines two or more reactants to form a single product, represented as A + B -> AB.
Combustion reaction occurs when a substance reacts with oxygen, releasing energy in heat and light.
Decomposition reaction involves a single compound breaking down into two or more substances, shown as AB -> A + B.
Single-replacement reaction features one element replacing another in a compound, exemplified by A + BX -> AX + B.
Double-replacement reaction entails the exchange of ions between two compounds, represented as AX + BY -> AY + BX.

A precipitate is a solid that forms in a solution during a chemical reaction.
Solutes are substances dissolved in water, forming an aqueous solution.
The solvent is typically water in an aqueous solution.

A complete ionic equation details all particles in a solution as they exist.
Spectator ions are ions that do not take part in the reaction; they appear as both reactants and products.
A net ionic equation simplifies the equation by excluding spectator ions, focusing only on the particles involved in the reaction.
