Chapter 3.2 Combination and Decomposition

Question 1

COMBINATION REACTIONS

Answer 1

2 or more substances react to form 1 product
2+x=1 product

1. metal + metal
2. metal + nonmetal
3. nonmetal + nonmetal

Question 2

IONIC SOLID

Answer 2

Combination reaction between a NONMETAL + Metal

Question 3

DECOMPOSITION REACTIONS

Answer 3

a single reactant breaks apart to form 2 or more substances. ( usually wen heated)
C—–> A+B

Question 4

COMBUSTION REACTION

Answer 4

rapid reactions that produce a flame … involve O2 from the air as a reactant

Question 5

Hydro Carbon and combustion

Answer 5

when combusted in the air react with o2 to form co2 and h2o.
HYDROCARBONS + O2= CO2 +H2O

.Wen there is insufficient quantity of o2 CARBON MONOXIDE IS PRODUCED (CO)

Question 6

INCOMPLETE COMBUSTION

Answer 6

.When there is insufficient quantity of o2 CARBON MONOXIDE IS PRODUCED (CO)

Question 7

SOOT

Answer 7

severly restricted o2 =SOOT ( fine partivles of Carbon

Question 8

COMPLETE COMBUSTION

Answer 8

Produces only Co2 and H20
