3. Salt
4. Vinegar
5. Sugar
6. Air Freshener
7. Onion
8. Lemonade
9. Bleach
10. Baking Soda
Task 1: Put the chemicals in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.
Name | Chemical | Image | Solid/Liquid/Gas |
Salt

COMPOUNDS, MIXTURES AND REACTIONS
Aim: To combine two compounds to see if there is a reaction.
Definitions:
- Element; A single form of a chemical
- Compound: A mixture made up of 2 or more elements
- Reaction: A process in which chemicals mix together to form a new substance.
- Mixture: When two or more elements are mixed together.

Observation of reaction
|
|
A teaspoon of the baking soda
was placed in a cup. 3 teaspoons of vinegar were then placed into the cup. |
The mixture bubbled, fizzed
and overflowed. |
When a reaction occurs between compounds / elements there is always an end result in the form of a solid/liquid or gas. This always results in a new element being formed. For this process to occur, one of the results can be hot or cold.
Task 3: What is the reaction that results when these compounds are mixed?

ReplyDeleteIt is nice to see you sharing some work on your blog. Can you have another look and make sure you are doing the correct post, I don't believe this is one of the activities we did together in class. We just need to see your 10 ingredients and their chemical names. Please check back to Mr Palmer's blog if you are unsure.
