Describe and illustrate how liquids are different then the other states of matter.

Answers

Explanation:

There are four natural states of matter: Solids, liquids, gases and plasma. ... Solids also have a high density, meaning that the particles are tightly packed together. Liquids. In a liquid, the particles are more loosely packed than in a solid and are able to flow around each other, giving the liquid an indefinite shape.

What factor is mostly responsible for the form of matter?
time
temperature
pressure
weather

Answers

Temperature is mostly responsible for the form of matter. For instance, when raising the temperature you're adding energy. This energy gives the individual molecules and atoms the ability to overcome the forces that hold them together. This can be seen when a solid turns into a liquid or a liquid turns into a gas. However, when you're lowering the temperature you're removing energy. The lack of energy results in less movement from the atoms. Gases condense into liquid because the atoms don't have enough energy to stay away from each other. Liquids solidify because the atoms don't have enough energy to slide past each other and they get stuck in place. So in conclusion, temperature determines how how much energy atoms have that allow them to move at different speeds which determines the state of matter.

1. As an electron in an atom moves from a higher energy state to a lower energy state, the atom
(A) becomes a negative ion
(C) releases energy
(B) becomes a positive ion
(D) absorbs energy

Answers

Answer:

(C) releases energy

Explanation:

From Bohr's model of the atom, we can understand the energy transitions involved when an electron moves from one energy level to another.

An electron in an energy level has a definite amount of energy associated with it at that level. When electrons change state, they must absorb or emit the exact amount of energy which will bring them from initial to final states. When the electron is excited, it moves from the ground state to an excited state, it must must absorb energy. On returning from an excited state, energy is emitted.

(C) releases energy

From Bohr's model of the atom:

We can understand the energy transitions involved when an electron moves from one energy level to another.

An electron in an energy level has a definite amount of energy associated with it at that level. When electrons change state, they must absorb or emit the exact amount of energy which will bring them from initial to final states. When the electron is excited, it moves from the ground state to an excited state, it must must absorb energy. On returning from an excited state, energy is released or emitted.

Therefore, option C is correct.

2. Using the following data, calculate the average atomic mass of magnesium (give your answer to the nearest
.01 ) : Show all work!
Isotope: Mg Percent abundance: 78.70%
24
Isotope: 'Mg Percent abundance: 10.13%
25
Isotope:
Mg Percent abundance: 11.17%
26

Answers

Answer:

24.32

Explanation:

From the question given above, the following data were obtained:

Isotope A:

Mass of A = 24

Abundance (A%) = 78.70%

Isotope B

Mass of B = 25

Abundance (B%) = 10.13%

Isotope C:

Mass of C = 26

Abundance (C%) = 11.17%

Average atomic mass of Mg =..?

The average atomic mass of Mg can be obtained as illustrated below:

Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

Average atomic mass = [(24 × 78.70)/100] + [(25 × 10.13)/100] + [(26 × 11.17)/100]

= 18.888 + 2.5325 + 2.9042

= 24.3247 ≈ 24.32

Therefore, the average atomic mass of magnesium (Mg) is 24.32

Mass can be changed into energy in a ____ reaction

A pizza is an example of a heterogeneous mixture. Explain why it is classified as such?​

Answers

Answer:

Hi!

So, a homogeneous mixture is when the parts that make up the mixture are all mixed in perfectly evenly, so they're only appearing as one uniform substance.

In a heterogeneous mixture, the pieces are not evenly mixed. A pizza has separate parts, like the crust and toppings, so it's a heterogeneous mixture.

What are minerals?

Minerals are defined as a chemical compound which has a well -defined composition and possesses a specific crystal structure.It occurs naturally in the pure form.

If a compound occurs naturally in different crystal structure then each structure is considered as a different mineral.The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.

Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure.It may also have variable composition which is split into separate species.

Physical properties of minerals include color,streak, luster,specific gravity and cleavage.
