What is a mixture? |
A combination of two or more different substances. |
|
|
What is a homogeneous mixture? |
A homogeneous mixture is made up of two or more substances that can be distinguished just by looking at them (has more then one visible phase) |
|
|
What is a heterogeneous mixture? |
A heterogeneous mixture is made up of two or more substances that can be distinguished just by looking at them (it has more then one visible phase). |
|
|
Name an example foreach of the two previous question. |
Heterogeneous: soda in a cup (we see the liquid and gaseous phase). Homogeneous: tea we don't see the mixtures (liquid phase and dissolved tea particles) |
|
|
What is a solution? |
It's a homogeneous mixture in which one or more substances are dissolved in another substance. |
|
|
What is a solute? |
In solution the substances being dissolved is called a solute. There is less solute than solvent in a solution. |
|
|
What is a solvent? |
The substance that the solute is being dissolved in is called a solvent. There is more solvent than a solute in a solution. |
|
|
Can solution s be solid, liquid and gaseous? |
Yes. For instance kitchen sinks are made of stainless steel but it also contains chrone, nickel and some carbon as solutes. The sea and nitrogen for solid and liquid. |
|
|
What do we call a metal combined with another substance? |
An alloy. |
|
|
What is an aqueous solution? |
It's a solution that uses water as a solvent. For example the sea would be an aqueous solution. |
|

Is a soda pops a heterogeneous or homogeneous mixture |
Heterogeneous |
|
|
What is a heterogeneous mixture |
Mixtures that contain several phases, made up of two or more substances that can be distinguished with our eyes. Have more than one visible phase. |
|
|
What is a homogeneous mixture? |
Has only one visible phase. Made up of two or more substances that cannot be distinguished with our eyes.bonly one visible phase. |
|
|
