Chemical Reactions Flashcards
Steps for double displacement
Step 1. Write reactants and products checking charges
Step 2. Balance with the big numbers (coefficients)
Step 3. Stop writing
Double replacement formula
Ab+SR -> Ar+SB
Single replacement formula
T+RS -> TS+R
Anything higher in the chart can replace it
Single replacement steps
Steps
- write all oft the elements with charges
- Balance with big numbers(coefficients)
- stop writing
Synthesis formula
R+S -> RS
XY+ZR -> XYZR
Steps for synthesis reactions
- Write compounds based on charges
- balance with coefficients
- Stop writing
Exceptions to rules(synthesis)
- Nonmetal oxide plus water
- creates one solution - Metal oxide plus water
- seated one solution - Metal oxide plus nonmetal oxide forms a salt
- dido
Decomposition formula
AB-> A+B
Exceptions for decomposition
Metal chlorates
Ex 2kclo3->2kcl+3O2
2. Metal carbonate decomposes
3. An acid makes a nonmetal oxide and water
4. Base(metal hydroxide) turns into metal oxide and water
Combustion formula
Any given +O2 ➡️ CO2+H2O
Metal oxide plus water makes a
Base
Nonmetal oxide plus water makes a
Acid
