Question 1

five types of reactions

Answer 1

synthesis, decomposition, combustion, single replacement, double replacement

Question 2

combination reaction

Answer 2

when two or more substances react to forma single new substance

Question 3

decomposition reation

Answer 3

chemical change in which a single compound breaks down into two or more simpler products

Question 4

single replacement

Answer 4

chemical change in which one element replaces a second element in a compound

Question 5

activity series

Answer 5

lists metals in order of decreaing reactivity. metal above others has ability to displace others

Question 6

double replacement

Answer 6

chemical change involging an exchange of positive ions between two compounds

Question 7

combustion reaction

Answer 7

chemical change in which an elemtn or a compound reacts with oxygen, producing energy in the form of heat and light

Question 8

predicting products of a combination

Answer 8

reactants generally two elements or two compounds where at least one is molecular

Question 9

predicting products of single replacement

Answer 9

reactants: an element and a compound (usually a metal or halide) see activity series

Question 10

predicting products of a double replacement

Answer 10

reactnats: two ionic compounds

Question 11

predicting products of combustion

Answer 11

reactants: oxygen and a compound of c, h
products: co2 and h20

Question 12

complete ionic equation

Answer 12

equatio that shows dissolved ionic compounds as dissociated free ions

Question 13

spectator ion

Answer 13

ion that appears on both sides of an equation and is not directly involved in the reaction

Question 14

net ionic equation

Answer 14

equation for a reaction in solution that shows only those particles directly involved in the chemical change

Question 15

net ionic is

Answer 15

balanced with respect to both mass and charge
