Week 17

over the past few weeks, we have been exploring many new ideas and concepts in chemistry.
first we learned about chemical properties/changes.
Chemical: associated with identity change
Chemical properties: flammability, oxidation, toxicity, chemical stability, combustibility
The we learned about the difference between compounds, elements, and mixtures.
i learned that compound is 2 or more atoms of different elements bound together and that elements are atoms that share all properties together. (Physical properties and chemical properties
A Mixture is 2 or more pure substances that are mixed together without being joined
Also over the past week, we have been learning about the period table of elements. We learned the difference between metals and non metals. For example:
Metals:
Solid at room temperature
Higher density
Hardness
Luster
Conductive(energy/heat and electricity)
Malleable

Non-metals
Liquids/gases at room temp
Poor conductors
No luster
Brittle in solid state
Then, we learned about the law of definite proportions which applies to elements like those of h20 where the proportion of the volume is definite.
Lastly, we did an experiment where we distilled Pepsi to see how much of it was water. Although we didn't figure out the answer, we figured out how to evaporate the water out of the Pepsi so that we could measure the amount.
