Types of Reactions & Balancing Flashcards
What is a synthesis reaction?
A reaction where 2 reactants combine to form 1 new substance
What is a decomposition reaction?
A reaction where one substance breaks apart into 2 or more substances
What is a single displacement reaction?
A reaction where 1 element takes the place (displaces) another element in a compound.
What is a double displacement reaction?
A reaction where 2 cations exchange places to form 2 new compounds.
Which reaction is like stealing a dance partner?
single displacement
Which reaction is like 2 dancing couples switching partners?
double displacement
What type of reaction does the following general pattern show?
X + Y –> XY

Decomposition
What is the law of conservation of mass?
A law that states that in any chemical reaction, the matter (atoms) can never be created or destroyed, only rearranged.
When balancing an equation, what should be balanced first?
A polyatomic
What is the number called that gets placed in front of a substance in order to balance it?
A coefficient
True or False; When a reaction occurs, the mass of the reactants will weigh less than the mass of the products.
False. The law of conservation of mass indicates the total mass of reactants will be the same as the total mass of the products.
