Predicting products

First identify the reax type Are the reactants (2 reactants) A + B ? Could be synthesis, Single Replacement, or Double Replacement. Ask are both single elements? Yes Synthesis, they combine No Ask is one a single element? Yes Single replacement (the single element becomes part of compound producing a new single element) NO Ask are both substances compounds? Yes Double replacement (Switch partners)

Ask: Is there only one reactant? Yes Decomposition (simply break apart the compound) No Ask: Is there only one product? Synthesis (combine reactants)

Are the products ONLY: CO2 and H2O Yes Look at reactants, Is O2 present? Is the other reactant a hydrocarbon (compound made of mostly H & C) Yes  Combustion
