Activity 1: What is Matter made of? Objective:
After performing the activity, you should be able to:
1. explain how these observed situations or events give evidence that matter is
made up of tiny particles
Materials:
clean tap water
Transparent glass
Spoon
10 ml alcohol/ 10 tablespoons of alcohol
50 ml water/ 1 cup of water
Procedure
1.Use a clean transparent glass, pour alcohol up to 20 ml (10 table spoon).
2. Measure 50 ml of water.
3. Add the 50 ml water to the alcohol and mix through. Observe the resulting solution
(Caution: Do not taste the solution)
01. What is the appearance of the resulting mixture?
Q2. Think about the alcohol and water as made of tiny particles. Give your reasons for the
observations you made in 01.
Q3.what is the volume of alcohol and water mixture?
Q4.is there a change of volume after mixing these two liquids?

answer:

1.A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly reffered to as sulotions. A heterogeneous mixture consists of visibly different substances or phrase.

2.For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling points. When the mixture is heated, one liquid evaporates before the other.

3.When 50 milliliters of water are added to 50 milliliters of alcohol, the volume of the two mixed together is only about 96 or 97 milliliters. When mixed together, the combined molecules fit together better than when they are alone, so they take up less space. Water and ethanol mix to form a solution.

4.Because the molecules of the two liquids are different sizes, their resulting intermolecular lattice can be better arranged to conserve more space. The mixture of the two liquids takes up less volume than the two liquids did separately.

Explanation:

Both of these liquids are polar. As such, they create intermolecular lattices, arranging themselves on the basis of the charges they carry and hydrogen bonding. Because of the necessary shapes of these lattices, these liquids don't "pack" (i.e. form lattices that conserve space) as well as if they were nonpolar. This creates spaces between the molecules.

When the two liquids are mixed, the molecules of the liquids can go into the other liquid's available spaces. They can do this because they are both polar and can mix freely. Because the molecules of the two liquids are different sizes, their resulting intermolecular lattice can be better arranged to conserve more space. The mixture of the two liquids takes up less volume than the two liquids did separately.

thanks me later

correct me if I'm wrong :)))

answer:

its a chemical mixing

Explanation:

if you add water and alcohol its chemical
