Chemical ____
This is a way to define a chemical reaction using elements in a compound and other various symbols
What is a chemical equation?
This means ‘written below’; it is written after a chemical symbol to determine the atoms in that element
What is a subscript?
This is a reaction where two elements combine to form another element.
What is a synthesis reaction?
This is used to slow down chemical reactions.
What is an inhibitor?
Mass is neither created nor destroyed during a chemical reaction.
What is the Law of Conservation of Mass?
This is a representation of elements in a compound and the number of the atoms of each element.
What is a chemical formula?
These are the elements before a chemical reaction has occured.
What are reactants?
This is a reaction where a substance breaks down into two or more substances.
What is a decomposition reaction?
What is an exothermic reaction?
(In order) A decomposition reaction is the opposite of this reaction. A double-displacement reaction is the opposite of this reaction. A synthesis reaction is the opposite of this reaction. A single-displacement reaction is the opposite of this reaction.
(In order) What is a synthesis reaction? What is a single-displacement reaction? What is a decomposition reaction? What is a double-displacement reaction?
This is a change in which one or more substances is converted into a new substance while energy is released or absorbed
What is a chemical reaction?
This is a number that represents the amount of units that each chemical taking part in a reaction has.
What is a coefficient?
This is a reaction where one element replaces another element.
What is a single-displacement reaction?
This is a chemical reaction where heat energy is absorbed.
What is an endothermic reaction?
This is the same and this is different about endothermic and exothermic reactions.
(Answers vary) What is that they both involve heat? What is endothermic absorbs heat and exothermic releases heat?
(Give the equation) Zinc plus lead two nitrate yield zinc nitrate plus lead.
What is Zn + Pb (NO3)2 → Zn(NO3)2 + Pb
These are the new chemical elements after a reaction.
What are products?
This is a reaction where a positive ion replaces another positive ion and forms two new compounds.
What is a double-displacement reaction?
This substance speeds up a chemical reaction.
What is a catalyst?
(Not in order) What is change in odor, color, smell, and temperature?
K4Fe(CN)6 + 6H2SO4 + 6H2O = 2K2SO4 + FeSO4 + 3(NH4)2SO4 + 6CO
What is a balanced chemical equation?
Means 'containing water'
What is aqueous?
This is a reaction where a substance reacts with oxygen and produces heat and light.
What is a combustion reaction?
This is an insoluble compound that comes out of solution during a double-displacement reaction.
What is a precipitate?
These are all of the parts in the following equation:
C6H6O + 7O2 --> 6CO2 + 3H2O
What is an element, a subscript, and a coefficient.
