Directions: Identify the type of chemical reaction from the UNbalanced equations

11) Decomposition Reaction. To be more specific, the chemical reaction is a decomposition of a binary compound.

12) Double Displacement Reaction. Also called Ionic Reaction

13) Cation Replacement Reaction

14) Double Displacement Reaction. Also called Ionic Reaction

15) Combustion Reaction

16) Synthesis Reaction. Also called Composition Reaction

17) Decomposition Reaction. To be more specific, the chemical reaction is a decomposition of a binary compound.

18) Cation Replacement Reaction  

the answer would be a

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
