Why are some constellations visible year-round, while others appear only part of the year?

Answers

Answer 1

Answer: Circumpolar constellations stay in the sky. Because of the rotation of the Earth and its orbit around the Sun, we divide the stars and constellations into two groups. Some stars & constellations never rise nor set, and they are called circumpolar.

Answer 2

Answer: circumpolar constellations stay in the sky. Because of the rotation of the Earth and its orbit around the sun, we divide the stars and constellations into 2 groups. Some stars and constellations never rise nor never set, and they are called circumpolar. Thus only some constellations are visible year- round

Which of the following is not a result when a change to an equilibrium system is applied? (2 points)Increasing the rate of the forward reaction will cause a shift to the left.

Increasing the rate of the reverse reaction will cause a shift to the left.

Decreasing the rate of the forward reaction will cause a shift to the left.

Decreasing the rate of the reverse reaction will cause a shift to the right.

Answers

Answer: Option (2) is the correct answer.

Explanation:

According to LeChatelier principle, any change in the equilibrium of a chemical reaction will result in shifting of equilibrium which is opposing the change.

Therefore, when we increase the rate of the reverse reaction that is, we move towards left side then this will actually cause a shift to the right hand side which is opposing the change.

Thus, we can conclude that increasing the rate of the reverse reaction will cause a shift to the left is not a result when a change to an equilibrium system is applied.

It should be increasing the rate of the forward reaction will cause a shift to the left because the external stress, which is the increase in rate, will cause the reaction to be unbalanced, and to reach equilibrium it needs to shift to the right.

What are nonexamples of mass

Answers

For something to have any mass as all, it has to take up space and have weight. BUT, some things don't take up any space or have weight as all...
Some things that dont have mass at all are: light, emotions, thoughts, and more...

Nonexamples of mass include concepts or entities that do not possess mass. Examples of such nonexamples are thoughts, emotions, energy, and light.

What are nonexamples of mass?

Nonexamples of mass include concepts or entities that are not considered to have physical substance or do not exhibit the property of mass. Some nonexamples of mass include ideas, emotions, time, and mathematical concepts. These entities are abstract and do not possess the physicality or measurable mass associated with material objects.

While thoughts and emotions are subjective experiences within the mind, energy and light are forms of radiation or wave-like phenomena that do not have a measurable mass component. Mass is a property associated with matter, which refers to the physical substance that occupies space and possesses inertia.

V\3. The atomic masses of any two elements contain the same number of _a. atoms
b. grams
c. ions
d. milliliters

Answers

a. atoms

Explanation:

Let's take as example carbon and lead. Carbon have an atomic mass of 12 a.m.u while lead have an atomic mass of 207 a.m.u. Value of atomic masses are the same with as the value of molar masses. So carbon have a molar mass of 12 g/mole while lead have a molar mass of 207 g/mol.

Avogadro's number it tell us that in 1 mole of particular substance there are 6.022 × 10²³ particles. Taking in account this, in 12 g of carbon there are 6.022 × 10²³ carbon atoms and in 207 g of lead there are 6.022 × 10²³ lead atoms atoms.

The atomic mass of any two elements contain the same number of atoms.
