Answer 6

used in place of ——> for reversible reactions

Question 7

(s)

Answer 7

solid

Question 8

(l)

Answer 8

liquid

Question 9

(g)

Answer 9

gas

Question 10

(aq)

Answer 10

aqueous

Question 11

triangle about the arrow

h above the arrow

Answer 11

indicates that heat is supplied to the reaction

Question 12

element above the arrow

Answer 12

indicates the substance was used as a catalyst

Question 13

Combination/Synthesis Reaction

Answer 13

two or more reactants come together and form ONE product

Question 14

Decomposition

Answer 14

break compound into elements

AB -> A + B

Question 15

Single replacement

Answer 15

Switch the halogens or metals
A + BC -> B +AC

• if a metal is more reactive it will replace the other metal
• if a halogen is more reactive it will replace the other halogen

Question 16

double replacement

Answer 16

switch metals

AX + BY -> AY + BX

Question 17

combustion

Answer 17

C+H + O2 -> CO2 + H2O

Question 18

When an ionic compound dissolves in water…

Answer 19

it dissociates into cations and anions

Question 20

complete ionic equation

Answer 20

shows dissolved ionic compounds as dissociated free ions

Question 21

net ionic equation

Answer 21

only shows what involved in making the main product

Question 22

spectator ion

Answer 22

ion that appears on both sides of the equation but is not directly involved in the reaction of the main product

Question 23

DECOMP RULE #1:

Carbonates

Answer 23

(CO3)^-2 compounds give off carbon dioxide and an oxide compound

Question 24

DECOMP RULE #2
