Is Squeezing oranges to make orange juice a chemical or physical change?

Answers

Answer 1

Answer: This would be a physical change because despite the fact the juice has been squeezed out of it, the orange is still an orange. A physical change is when something changes matter, like a solid to a liquid or a liquid to a gas. Since it's been changed from a solid orange to liquid juice, it's a physical change.

Hope I helped! :)

Answer 2

Answer: squeezing just the juices out of the orange, like with your hand or whatever you use, is a physical change. yes :)

Under conditions when glucose oxidation is elevated, the acetyl-CoA produced will allosterically activate which of the following enzymes leading to an increase in the production of oxaloacetate?a. Pyruvate carboxylase

b. Citrate lyase

c. Acetyl-CoA carboxylase

d. Malate dehydrogenase

Answers

The correct answer is ( a. Pyruvate carboxylase).

When glucose oxidation is elevated, the acetyl-CoA produced will allosterically activate the enzyme pyruvate carboxylase, leading to an increase in oxaloacetate production.

Describe meteor showers

Answers

Answer:

a rain of asteroids coming from space

Explanation:

Meteor showers occur when dust or particles from asteroids or comets enter Earth's atmosphere at very high speed. When they hit the atmosphere, meteors rub against air particles and create friction, heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.

A solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solution must beA)dilute B) saturated C) unsaturated D) supersaturated

Answers

Answer: Option (B) is the correct answer.

Explanation:

A solution that has maximum concentration of solute particles and on adding more solute the particles of solute remains undissolved is known as a saturated solution.

Whereas when particles of solute keep on dissolving in a solution then it is known as an unsaturated solution.

Thus, we can conclude that a solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solution must be saturated.

when the solute can no longer dissolve in the solution the solvent becomes SATURATED. When no more solute can dissolve and if you look at the bottom of the beaker, test tube, pan, or glass of cold tea you can see the solute permeating out as little particles .

Which is a correct comparison between the modern quantum model and John Dalton’s model of the atom?A.The modern model is not as widely accepted by scientists as Dalton’s model.
B. The modern model states that atoms of all elements are identical, whereas Dalton’s model does not.
C. The modern model recognizes particles in the atom, whereas Dalton’s model does not.
D. The modern model does not explain emission spectra, whereas Dalton’s model does.

Answers

The modern model recognizes particles in the atom, whereas Dalton’s model does not. The correct option is C.

What is an atom?

An atom is a matter particle that truly represents a chemicalelement. An atom is made up of a central nucleus encircled by one or more electrons.

Each electron carries a negative charge. The nucleus is positively charged and encompasses one or more protons and neutrons, which are relatively heavy particles.

According to current theory, electrons are in orbits all over the nucleus, which is made up of protons and neutrons.

It also indicates that all orbits are not the same and that their structures differ. According to quantumtheory, waves are associated with the properties of matter.

Dalton'smodel does not recognize particles in the atom, whereas the modern model does.

Thus, the correct option is C.

Depends on your definition of the modern model. The one created by Neils Bohr differs from the quantum mechanical model.

For the Quantum mechanical model, A is untrue. The QM model is far more accepted than Dalton's because it explained the workings of the atom far better than any before.
For the NB model however, that was not accepted as much because it only worked when working with Hydrogen.

B: No model states that each atom is identical.

C: Dalton's model did NOT recognize particles in the atom, but the NB and QM models do.

D: The reverse is true.

So the answer is C.
