1
What is the formation of solid in a previously clear solution
Precipitation reaction
2
What is it called when the formation of gas is evidence of a chemical reaction
Gas evolution reaction
3
Is there a indefinite signs of a chemical change
No, there is a definite
4
What do we represent a chemical reaction with
Chemical equation
5
What side is the product on
What side is the reaction on
Product-left
Reaction-right
6
A chemical equation in which the number of each element has teh same amount on both sides
Balanced equation
7
To balance equations what to we insert
Coefficients
8
What cant you change to balance an equation
Subscript
9
What is an aqueous solution
Homogeneous mixture of a substance with water
10
T/F water can conduct electricity
F can not conduct electricity
11
Ions in a sodium chloride studio conduct electricity, causing the light to light up. Solutions such as NaClare called strong
Electrolyte solutions
12
What is a solution containing a solute that dissociates into ions; therefore, a solution that conducts electricity well.
Strong electrolyte solution
13
Dissolves in solutions
Soluble
14
doesn't dissolve in water
Insoluble
15
A set of empirical rules used to determine whether an ionic compound is soluble
Solubility rules
16
A reaction that forms a solid or precipitate when two aqueous solutions are mixed.
Precipitation reactions
17
An insoluble product formed through the reaction of two solutions containing soluble compounds.
Precipitate
18
T Only insoluble compounds form precipitates
T precipitates
19
chemical equation showing all the species as they are actually present in solution
Complete ionic equation
20
Ions that do not participate in a reaction; they appear unchanged on both sides of a chemical equation.
Spectator ions
21
An equation that shows only the species that actually participate in a reaction
Net ionic equation
22
A chemical equation showing the complete, neutral formulas for every compound in a reaction
Molecular equation
23
reaction that forms water and typically a salt.
Acid-base reaction
24
A reaction that occurs in solution and forms a gas as one of the products.
Gas evolution reaction
25
What are acid base reactions also called
Neutralization reaction
26
An ionic compound that usually remains dissolved in a solution after an acid-base reaction has occurred.
Salt
27
A reaction in which electrons are transferred from one substance to another.
Oxidation reduction reaction/ redox reactions
28
T/F redox reactions are responsible for rust, bleaching hair, and the electricity in batteries
T
29
T/F redox reactions never involve the reaction of the substance oxygen
F usually
30
Oxidation means
loss of electrons
31
Reduction means
Gain of electrons
32
Reds 3 rules
1.)instance reacts with element oxygen
2.) metal reacts with nonmetal
3.) more generally, one substance transfers electrons to another substance
33
A reaction in which a substance reacts with oxygen, emitting heat and forming one or more oxygen-containing compounds.
Combustion reaction
