Flashcards in Ch 7 Deck (34)
What is the formation of solid in a previously clear solution
What is it called when the formation of gas is evidence of a chemical reaction
Gas evolution reaction
Is there a indefinite signs of a chemical change
No, there is a definite
What do we represent a chemical reaction with
What side is the product on
What side is the reaction on
A chemical equation in which the number of each element has teh same amount on both sides
To balance equations what to we insert
What cant you change to balance an equation
What is an aqueous solution
Homogeneous mixture of a substance with water
T/F water can conduct electricity
F can not conduct electricity
Ions in a sodium chloride studio conduct electricity, causing the light to light up. Solutions such as NaClare called strong
What is a solution containing a solute that dissociates into ions; therefore, a solution that conducts electricity well.
Strong electrolyte solution
Dissolves in solutions
doesn't dissolve in water
A set of empirical rules used to determine whether an ionic compound is soluble
A reaction that forms a solid or precipitate when two aqueous solutions are mixed.
An insoluble product formed through the reaction of two solutions containing soluble compounds.
T Only insoluble compounds form precipitates
chemical equation showing all the species as they are actually present in solution
Complete ionic equation
Ions that do not participate in a reaction; they appear unchanged on both sides of a chemical equation.
An equation that shows only the species that actually participate in a reaction
Net ionic equation
A chemical equation showing the complete, neutral formulas for every compound in a reaction
reaction that forms water and typically a salt.
A reaction that occurs in solution and forms a gas as one of the products.
Gas evolution reaction
What are acid base reactions also called
An ionic compound that usually remains dissolved in a solution after an acid-base reaction has occurred.
A reaction in which electrons are transferred from one substance to another.
Oxidation reduction reaction/ redox reactions
T/F redox reactions are responsible for rust, bleaching hair, and the electricity in batteries
T/F redox reactions never involve the reaction of the substance oxygen
loss of electrons
Gain of electrons
Reds 3 rules
1.)instance reacts with element oxygen
2.) metal reacts with nonmetal
3.) more generally, one substance transfers electrons to another substance
A reaction in which a substance reacts with oxygen, emitting heat and forming one or more oxygen-containing compounds.
