Chapter 10 Flashcards
In a combustion reaction look for
Oxygen on the reactant side
Oxide on the product side
In a synthesis reaction 2 or more substances react to make
A single product
Also called direct combination
Decomposition reaction is when
Single reactant breaks down into 2 or more substances
Single replacement will occur if the metal is by itself only if
Its more reactive then the metal in the compound
The uncombined metal displaces the metal in the compound
Double replacement reaction produces
2 new substances
A chemical reaction occurs when a substance reacts to form
New substances
Beginning material
Reactants
End materials
Products
Chemical equation
Represents a chemical reaction
➡️
Yields to
Equals
In a balanced chemical equation the total number of atoms of each kind of element must be the
Same
The law of conservation of matter states that
Matter cant be created or destroyed
This means that the mass of the reactants
Equals the mass of the products

Activity series tells us
How likely a metal is to react
When a more reactive metal is alone it will replace a less reactive metal in the compound this is known as
Single displacement replacement
A solution is
Solute+solvent
Solute
The substance that is dissolved
Solvent
The substance that does the dissolving
