The image shows the particles of a substance in its three states. The kinetic energy of the particles increases as:
Certain types of metals, like gold, are both naturally occurring and can be created in a lab. (This process is not used often because it is expensive and not efficient!) This tells us what about metals like gold?
Which of these is NOT an example of a chemical reaction?
Combustibility, toxicity, PH, reactivity, ability to rust, and flammability are all examples of:

The particles in the image on the far left most likely:
Heating Zinc Chloride to its melting point of 290 °C and watching it turn to a liquid is an example of:
