How are solutions and mixtures alike? 

• They are a combination of substances
• They are both chemically combined
• they can be separated immediately
• they have no similarities

How are mixtures and solutions different form each other? 

• there are no differences 
• once combines chemically the other combines electronically 
• they have more than one elements in them
• the mixture combines physically and the solution is not easily separated
