Matter

Explanation:

Solids, liquids, and gases are the three types of matter that can be found in the world around us today. In solids, all of the particles are close together. They move more in liquids, but they are spread out in gas.

In giant covalent structures such as graphite or diamond, the atoms form strong bonds by sharing electrons. Therefore, the given statement is true.

A covalent bond can be defined as a chemical connection formed by the sharing of electron sets between particles. A covalent bond can be created by the mutual sharing of electrons from both atoms.

The pair of electrons that are shared in this kind of bonding is known as the shared or bonding pair. Covalent bonds are the sharing of bonding pairs of electrons that will provide the stability of the atom in its outer shell.

Elements that have very high ionization energies are incapable of exchanging electrons or elements having low electron affinity cannot accept electrons. Covalent bonding between two non-metallic atoms is characterized by the equal sharing of electrons between the atoms and covalent bonds with an electronegativity difference of participating atoms is more than 2.0.

Therefore, a giant structure like a diamond has strong covalent bonds that require a lot of energy to break.

Answer:

It will be solid

Explanation:

-78 C° is the freezing point of carbon dioxide, so at the temperature of -78 Celsius, the particles of carbon dioxide will come closer together and have about a fixed position to vibrate. The carbon dioxide will turn into solid. The solid form of carbon dioxide is also called dry ice.

Answer:

Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!

Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.

Hope that helps.

Answer:

A = 55

Explanation:

The atomic number is the number of protons also = the number of electrons, so basically we have 29 neutrons, 26 electrons and 26 protons. Anyway, it's asking the mass number which is the neutrons + the protons, so you just take 29+26 = 55

Atomic number=26

Neutrons=29

Electrons=26

Mass number=Proton+neutron

Protons=26

Mass number=26+29

=55

Answer:

6 moles

Explanation:

3 moles of O2 produce 2 moles of Al2O3 so in order to produce 4 moles pf AL2O3 you need 4 x 3 /2 moles of O.

Answer:

The poster should include:

 TITLE: Creative name of superhero.

 DESCRIPTION OF ELEMENT SUPERHERO (2 PARAGRAPHS):

This section should include a brief description of how your superhero acquired, used, or lived

with their element power. You may want to describe where does your superhero element lives

(where in nature can it be found). What are his/her superpowers? Does your superhero

element have a hideout? What are his/her strengths? What is his/her weakness? Who is

his/her arch nemesis (evil super villain)? What kind of super suit does your superhero have?

 5 FACTS:

This section should include at least 5 fun facts about your element. You can choose to

describe facts that illustrate where your element is found in nature. You may also wish to

describe what is your element used for. You may address what are characteristics of your

element or what are important uses of your element. For example, can your element be made

into something useful or can your element combine with other elements to make something

totally different.)

 ATOMIC DRAWING

Include the atomic structure of your element with correct labeling of its protons neutrons,

electrons. Make sure your drawing has the correct number of protons, neutrons, electrons.

 DRAWING OF YOUR ELEMENT SUPERHERO

This section should include a drawing (in color) of your Element Superhero on a clean sheet of

WHITE paper. You may want to draw your Element Superhero fighting his nemesis (super

villain). Or you may want to draw your Element Superhero using his special powers.Explanation:

Answer is below with the steps in order

Explanation:

4) Blood picks up carbon dioxide from the body

7) Heart pumps carbon dioxide rich blood to the lungs

8) Inhale

9) Nose traps germs in air

10) Air moves down the trachea

3) Air moves through bronchi into the bronchioles

6) Alveoli receive oxygen pass to blood

9) Oxygen passes into the blood

11) Alveoli receives carbon dioxide from the blood

12) Oxygen-rcih blood flows to the heart

3) Carbon Dioxide moves from bonchioles to bronchi

13)Carbon dioxide flows up

1) Heart pumps oxygen-rich blood to the body

The last four of five steps could be switched up a little bit since it all happens synchronously, but this is the most accurate interpretation.

The statements in the correct order are:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Answer:

Explanation:

Taking into account the definition of Avogadro's Number, the correct answers are:

1 mole of any element contains 6.023×10²³ atoms

1 mole of any compound contains 6.023×10²³ molecules

You have to know that Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole.

Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.

Avogadro's number applies to any substance, because the number of elementary units in a mole of a substance is, by definition, a  constant that does not depend on the material or the type of particle considered.

So, in this case, the correct answers are:

1 mole of any element contains 6.023×10²³ atoms

1 mole of any compound contains 6.023×10²³ molecules

80 percent

About 80 percent of the elements are metals (shiny elements that conduct heat and electricity well), and 15 percent of the elements are nonmetals (poor conductors of heat and electricity). The remaining elements are metalloids, which share properties of both metals and nonmetals.

Answer:

80% of the Periodic Table consists of metals and 15% non-metals and 5% other elements.
