- double-displacement reaction
- takes place if a precipitate, water, or gas forms when two ionic compounds in solution are combined.
- synthesis reaction
- two or more substances combine to form another substance
- products
- the new substances produced
- precipitate
- an insoluble compound formed during this type of reaction.
- coefficients
- represent the number of units of each substance taking part in a reaction
