Checkpoint Bohr Mod
Which of the following statements is NOT true of Lewis Dot Diagrams?
Give us a way to show the valence electrons without having to draw the entire Bohr
The valence electrons determine whether or not the atom will react with other atoms
Atoms strive to be stable with a full valence shell so they will give, take, or share ele
shell.
Include all of the known electrons for the atom it represents.

Answers

Answer 1

the last option: include all of the known electrons for the adam it represents

that statement is not true because Lewis dot structures only show valence electrons

Classification of Matter
Everything that has mass and volume is made of matter.
Atoms are the building blocks of matter. They cannot be broken down into smaller pieces using chemical reactions or physical changes. Various groups of atoms compose all known matter. Matter can be classified into two major categories: pure substances and mixtures.
Pure Substances
A pure substance is a type of matter that is made up of only one kind of material. All the particles (i.e., atoms or molecules) in a pure substance are the same, and the same properties are exhibited throughout the substance. There are two main types of pure substances: elements and compounds.
Elements—Elements are the simplest pure substance because they are made up of only one type of atom. For example, the element carbon is only made up of carbon atoms, and the element zinc is only made up of zinc atoms. The simplest unit of an element that still has the properties of that element is the atom. However, the atoms of some elements are naturally found bound to other atoms of the same element in two-atom units called diatomic molecules.
Today, there are over 100 known elements. These elements are represented by chemical symbols (e.g., C represents carbon and Zn represents zinc) and are listed in order of their atomic numbers on the periodic table.
The particle diagrams above model particles of elements. Single atoms of helium gas are shown on the left. Diatomic molecules of nitrogen are shown on the right.
Compounds—Compounds are pure substances that are made up of more than one type of element, chemically combined in a fixed ratio. Depending on the type of compound, its simplest unit may be a molecule or a repeating crystal pattern.
Although the properties of a compound differ from the properties of the elements that compose it, the molecules of a compound exhibit the same properties as one another. Also, since the elements within a compound are chemically combined, they can only be separated by chemical changes, such as the change caused by electrolysis.
Compounds have a definite chemical composition that can be identified using a chemical formula. Water (H2O), salt (sodium chloride, NaCl), and sugar (glucose, C6H12O6) are all examples of compounds.
The particle diagrams above show compounds. The diagram on the left models molecules of water. The diagram on the right models molecules of carbon dioxide.
Mixtures
Mixtures are made up of two or more substances that are not chemically combined. Because they are not chemically combined, the substances retain their own properties of matter, even though they are mixed together. Furthermore, mixtures can be separated by physical means, such as filtration or distillation.
The diagram on the left shows a mixture of diatomic molecules that contain only one type of atom. The diagram on the right shows a mixture of two different compounds whose molecules contain two different types of atoms.

B.
the sand and gravel can be separated with a sieve.
C.
the mixed sand and gravel will stick together.
D.
the mixed sand and gravel have a lower volume.

Answers

Answer:

Explanation:

There are two types of mixture, one is homogeneous mixture and other is heterogeneous mixture. Therefore, the correct option is option B that is the sand and gravel can be separated with a sieve.

What is mixture?

When two or more compounds are combined but each ingredient retains its chemical identity, the result is referred to as a mixture. In other words, there is no chemical interaction between the parts of a combination. According to how consistent they are and how well the components' particle sizes match up, mixtures are categorized.

Sand and gravel in a mixture have the same properties as sand and gravel when they are not mixed. Since gravel is bigger than sand, the sand and gravel can be separated with a sieve.

If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.

It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

In 3 paragraphs, describe how weathering changes the earth's surface. Please do not copy and paste.

Answers

Answer:

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.

The effects of weathering disintegrate and alter mineral and rocks near or at the earth's surface. This shapes the earth's surface through such processes as wind and rain erosion or cracks caused by freezing and thawing. Each process has a distinct effect on rocks and minerals. Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases Figure below. With more surfaces exposed, there are more surfaces on which chemical weathering can occur. Mechanical weathering may increase the rate of chemical weathering.

Weathering, erosion, and deposition are processes that act together to wear down and build up the Earth's surface. These processes have occurred over billions of years. Weathering is any process that breaks down rocks and creates sediments. Weathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.

Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O

Answers

Answer:

Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.

CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.

N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.

NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.

H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.

Overall, the scale can be represented as follows:

100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

I’ll give the definitions for half of them ( 2 ) CO2 is Carbon dioxide and H20 is the scientific word for Water/ Aqua
