The inputs of a chemical reaction are called this

Reactants

100

___ Na + ___ O2 ---> ___ Na2O

4 Na + O2 ---> 2 Na2O

100

P4 + 3 O2 ---> 2 P2O3

Synthesis

100

K + Cl2 --->

Predict the products and balance 

2K + Cl2 ---> 2KCl

100

Some reactions are reversible, meaning that the reaction proceeds in both directions. When no net change occurs in the amount of reactants and products, a system is said to be in 

Equilibrium

200

A reaction in which energy is absorbed

Endothermic

200

___ NH4OH + ___ H3PO4 ---> ___ (NH4)3PO4 + ___ H2O

 3 NH4OH +  H3PO4 ---> (NH4)3PO4 + 3 H2O

200

O3 ---> O + O2

Decomposition

200

Li + N2 --->

Predict the products and balance

6Li + N2 ---> 2Li3N

200

is a substance that speeds up the rate of a reaction without being permanently changed or used up itself.

Catalyst

300

a number, which is always positive, that is placed in front of the parts of a chemical reaction to indicate how many units are involved

Coefficient

300

___ AgI + ___ Fe2(CO3)3   --->  ___ FeI3 + ___ Ag2CO3

6 AgI +  Fe2(CO3)3   --->  2 FeI3 + 3 Ag2CO3

300

2 AgNO3 + Cu ---> Cu(NO3)2 + 2 Ag

Single Displacement

300

C4H6 + O2 --->

Write the products and balance the equation

2 C4H6 + 11 O2 ---> 8 CO2 + 6 H20

300

The amount of energy particles must have when they collide is called this

Activation energy

400

small-sized number on the bottom right of an element's symbol; it refers to the number of atoms of the element

Subscript

400

___ Na + ___ NaNO3 ---> ___ Na2O + ___ N2

10 Na + 2 NaNO3 ---> 6 Na2O +  N2

400

 2 Na +  2 H2O --->  2 NaOH +  H2

Single Displacement

400

Pb(NO3)2 + KOH --->

Predict the products and balance

Pb(NO3)2 + 2KOH ---> Pb(OH)2 + 2KNO3

400

An insoluble product that is formed after a chemical reaction 

Precipitate

500

The kind of reaction in which a substance rapidly combines with oxygen to form one or more oxides

Combustion

500

___C10H22 + ___ O2 ---> ___ CO2 + ___ H2O

2 C10H22 + 31 O2 ---> 20 CO2 + 22 H2O

500

C3H6O + 4 O2 ---> 3 CO2 + 3 H2O

Combustion

500

HCl + Mg(OH)2 ---> 

Predict the products and balance

2HCl + Mg(OH)2 ---> MgCl2 + 2H2O

500

In which direction would this equation shift if I were to remove some carbon dioxide?

CaCO3 ⇋ CaO + CO2 

To the right; if CO2 is removed, the reaction will favor more production of CO2 to reestablish equilibrium, the reaction will favor the decomposition of limestone, producing more lime and CO2
