Question | Answer |
---|---|
gas evaluation | evidence of chemical reactions |
insoluble solid is produced in solution | evidence of cemical reactions |
a permante color change is observed | evidence of chemical reactions |
an energy change is observed | evidence of chemical reactions |
combination reaction or combustion | simple substances combined giving a complex compound. a+b --> ab |
decomposition reaction/sublimation | single compounds compound becomes simple compound abc= a+b+c |
single displacement reaction/ single replacement reactions | single anion is kicked out of equation. most reactive metal will displace least reactive metal |
metals are arranged in | decreasing order of reactivity. Li>Al |
double displacement reaction/ double replacement reaction | both anions will be displaced, cations will switch or exchange anions |
neutralization reaction/acid-base | acid reacts with base and neutralizes. produces salt and water |
