All Flashcards
What is the general form of a synthesis reaction?
A + B → AB
What is the general form of a decomposition reaction?
AB → A + B
What is the general form of a combustion reaction?
Hydrocarbon + O2 → CO2 + H2O
What is the general form of a single replacement reaction?
AB + C → AC + B
What is the general form of a double replacement reaction?
AB + CD → AD + CB
What is the key difference between physical and chemical changes?
Physical changes alter form, chemical changes create new substances.
Compare and contrast synthesis and decomposition reactions.
Synthesis combines reactants into one product; decomposition breaks one reactant into multiple products.
What is the main difference between single and double replacement reactions?
Single replacement involves one element swapping; double replacement involves two compounds exchanging ions.
What is the effect of a hydrocarbon reacting with oxygen?
Combustion, producing CO2 and H2O.
What is the result of mixing aqueous solutions of lead(II) nitrate and potassium iodide?
Formation of a yellow precipitate (PbI2).
