🗑
Gas   no fixed volume or shape  
🗑
Liquid   a distinct volume independent of its container but has no specific shape  
🗑
Solid   a definite shape and volume  
🗑
Solutions   groups of molecules that are mixed up in a completely even distribution  
🗑
Compound   substances composed of two or more elements  
🗑
Pure Substance   matter that has distinct properties and a composition that doesn't vary from sample to sample  
🗑
Elements   cannot be decomposed into simpler substances (building block)  
🗑
Mixture   combinations of two or more substances in which each substance retains its own chemical identity  
🗑
Homogenous mixture   solutions are also mixtures, but all of the molecules are evenly distributed  
🗑
Alloys   mixture of two or more metals  
🗑
Emulsions   mixture of oils and waters  
🗑
Solute   the substance to be dissolved  
🗑
Solvent   the one doing the dissolving  
🗑
Solubility   the amount of solute that can be dissolved by the solvent  
🗑
Colloids   solutions with much bigger particles, usually foggy or milky when looked at  
🗑
Molecule   general term used to describe atoms connected by chemical bonds, every combination of atoms is a molecule  
🗑
Covalent compounds   happen when the atoms share the electrons  
🗑
Ionic compounds   happen when electrons are donated from one atom to another  
🗑
Electrons   negatively charged particles of the atom  
🗑
Matter   anything that has mass and takes up space  
🗑
Physical forces   create the changes (alone cannot break down compounds)  
🗑
Chemical Forces   bonds are built and broken down  
🗑
Heterogeneous mixtures   in which the two or more substances that form the mixture are not evenly distributed  
🗑
Suspensions   heterogeneous fluid mixtures containing solid particles large enough for sedimentation  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
