some students observe four different lab investigations. The students record their observations in a table.
Investigation
Observations
1
A beaker of water is
heated on a hot plate. Bubbles form in
the water, and steam is given off.
2
Oil is added to a beaker of water. Oil forms a layer on top
of the water
3
Sand and iron filings are mixed in a beaker. A magnet is
then used to separate the iron filings from the sand.
4
A piece of chalk is placed in a beaker of vinegar Bubbles
form as a gas is given off.
Which investigation most likely involved a chemical reaction?
Answer:
Number 4 is an example of a chemical reaction
Explanation:
heThe chalk is reacting with the vingear which is creating a new substance. The new substance is the gas that the reaction gives off.

Explain how you could use the solubility of a substance to make a saturated solution.
O 9 ? A B с The models above show particle arrangement. The following statements compare and contrast the models. 1. The substance in diagram A has the highest density. 2. The substance in diagram A has the highest energy. 3. The substances in diagrams B and C would flow freely. 4. The substance in diagram C has the lowest temperature. 5. The substances must undergo a chemical change to transform into a different model.
Answer: 2 The substance in diagram A has the highest energy
Explanation:
Answer:
On my test, I have to choose which of the 5 statements are correct. 1 and 3 are definitely correct. 5 is NOT correct as this is matter we are talking about. When matter changes that is a physical change and NOT a chemical change.

What happens to salt water and fresh water when you try to mix them.
Answer:
the lighter fresh water rises up and over the salt water
Explanation:
this is because the salt water is denser
Answer:
When trying to mix fresh/salt water it leads to variable and dynamic chemical conditions, especially salinity because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.
