Identify some beverages that are mixtures. Classify them as solutions, suspensions, or neither. Explain your classifications.
Minchanka [31]

Answer:

See explanation.

Explanation:

Hello.

In this case we can for instance take into account the following mixtures:

- Orange juice.

- Tea.

- A soda.

- Salty water

- Coffee.

Thus, since the orange juice is a suspension as long as it contains different sizes of orange pulp particles that cannot be dissolved mostly because of its organic nature.

Tea can be a solution when we place a tea bag in a cup with warm water since just soluble components of tea are successfully dissolved in the water. Moreover, homemade tea based on some plants are fruits may behave as a suspension due to the oraginic particles that are not dissolved in the water yet suspended.

A soda is a solution of some water-soluble compounds, gaseous soluble carbon dioxide and water which are homogeneously distributed in the solution.

Salty water can be a solution if you put some salt in warm or just cold water and wait until it dissolves completely.

Coffee can be also a solution or suspension depending on how it is made, which type of coffee is used and the amount of coffee added to the hot water.

Best regards.

Using these facts, describe the universe in 30 or less words
rosijanka [135]

Answer:

Astronomers can use telescopes to look at very distant galaxies. This is how they see what the Universe looked like a long time ago. This is because the light from distant parts of the Universe takes a very long time to reach us. From these observations, it seems the physical laws and constants of the Universe have not changed.

Physicists are currently unsure if anything existed before the Big Bang. They are also unsure whether the size of the Universe is infinite.
