300

What is the equation for power?

Power = Energy transferred/Time

400

What is the difference between heterogeneous and homogeneous?

Heterogenous is a mixture that you can see the different parts and can easily be separated

Homogeneous is a mixture that is evenly mixed and cannot be separated easily.  

400

What is the difference between crystalline solids and amorphous solids?

Crystalline solids are arranged in a regular repeating pattern that are made up of crystals. 

Amorphous solids aren't arranged in a regular pattern and does not melt at a specific temperature.

What is the difference between exothermic and endothermic reactions?

Exothermic releases energy. While endothermic requires more energy.

500

What is the difference between a colloid and a suspension? 

A colloid is a mixture between small undissolved particles that do not mix. A suspension is a mixture of which particles can be seen and easily separated. 

500
