Chemical Equations Flashcards
(6 cards)
1
Q
What is a chemical equation
A
This tells us the reactants(left) and products(right)
2
Q
What does an equation tell us
A
This tells us the ratio in which the reactants and the ratio of products formed
3
Q
In what conditions are state symbols very important, in a ionic equation
A
When a precipitate or gas is formed
4
Q
What is an ionic equation
A
This is when the equation only consists of the reacting ions( all other species know as spectator ions)
5
Q
How do you work out ionic equations
A
This can be done by cancelling out the ions that are common to both sides of the equation, however a precipitate,liquid or gas can not be cancelled
6
Q
Turn the following into a ionic equation
MgCl2(aq)+2AgNO3(aq) –> 2AgCl(s) + Mg (NO3)2(aq)
A
2Cl(aq)+2Ag(aq)–>2AgCl(s)
