OUTLINE

Paragraph 1: Introduction

Paragraph 2: Body Paragraph

Paragraph 3: Body Paragraph

Paragraph 4: Body Paragraph

Paragraph 5: Conclusion

Think of the introduction and conclusion as “bookends” that serve to hold the essay tightly together. The

introduction will “push” into or initiate the examination of your topic and the angle you decide to focus on, while

the conclusion will “pull” tight all the ideas that you have gathered together for a unified essay.

Remember, the five-paragraph model can be expanded to include more body paragraphs that probe more deeply

into your subject. Check with your instructor to ensure whether or not you can exceed this length for an

assignment.

The introductory paragraph should include the following elements:

Background information: Enough information necessary for your reader to understand your topic

Thesis statement: Indicates your paper’s topic, makes your paper’s purpose clear, and provides an

overview of the three main supporting points that will unify the essay. The thesis statement is typically

the last sentence.

If you are writing in response to a text, the introduction should include the title, author, and genre of that

piece.

Begins with a topic sentence that identifies one main idea that will be discussed as support or proof for the

thesis statement

Supporting sentences use specific details, demonstrated through closely related examples or evidence, to

expand and explain the main idea. Generally, a well-developed paragraph has at least five to eight

sentences.

Paragraph unity means that all ideas in a paragraph are closely related to its topic sentence and further

develop that topic sentence. That is, all sentences in a single paragraph must be unified around a central

point or idea.

This paragraph, and any subsequent body paragraph, should begin with a topic sentence that signals the

reader that a new idea or point is being introduced.

As you organize your essay, keep in mind its coherence. Coherence refers to connections among

paragraphs and ideas—the logical sequence of your thoughts.

o Use transition words or phrases at the outset of your body paragraphs and to move from one idea

to another within your paragraphs.

o Have you transitioned logically from the main idea in the previous paragraph to this one? Are you

making clear connections among the paragraphs and ideas? Be sure to think about coherence during

the revision stage of the writing process.

This paragraph begins with the final topic sentence that relates back to the remaining point mentioned in the

thesis statement. Each paragraph should contain a new main idea.

Again, flesh out this main idea with specific examples, details, and relevant support.

Be sure to maintain paragraph unity. That is, each sentence must relate to your topic sentence.

The conclusion revisits your overall purpose for writing and often invites your reader to consider the

implications of why your ideas are significant.

The conclusion may restate the thesis, summarize the paper’s major points, or leave the reader with a final

thought to ponder. Several other methods for writing conclusions are included on a separate Tutoring Center

handout. If you choose to restate the thesis or summarize the essay’s main ideas, do not repeat the same

wording from the introduction or body paragraphs. Remember not to introduce new, unrelated ideas in the

conclusion

Answer: median :4.44 mean :4.11

Explanation:

i did test on Edge

Answer:

When the electrons in the atom are excited, for example by being heated, the additional energy pushes the electrons to higher energy orbitals. When the electrons fall back down and leave the excited state, energy is re-emitted in the form of a photon. The wavelength (or equivalently, frequency) of the photon is determined by the difference in energy between the two states. These emitted photons form the element's spectrum.

The fact that only certain colors appear in an element's atomic emission spectrum means that only certain frequencies of light are emitted. Each of these frequencies are related to energy by the formula:

{\displaystyle E_{\text{photon}}=h\nu }E_{\text{photon}}=h\nu ,

where {\displaystyle E_{\text{photon}}}E_{\text{photon}} is the energy of the photon, {\displaystyle \nu }\nu  is its frequency, and {\displaystyle h}h is Planck's constant. This concludes that only photons with specific energies are emitted by the atom. The principle of the atomic emission spectrum explains the varied colors in neon signs, as well as chemical flame test results (described below).

The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted.

Explanation:

Answer:

We are given the following equation:

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g)

we can see that the number of moles of H2O is 4/3 time the moles of CO2

So, the easiest way to find the number of moles of H2O is to find the number of moles of CO2 and multiply it by 4 / 3

Moles of CO2:

Molar mass of CO2 = 44 grams / mol

Moles of CO2 = Given mass / Molar mass

Moles of CO2 = 16.3 / 44 moles

Moles of H2O:

Moles of H2O = Moles of CO2 * 4 / 3

Moles of H2O = 16.3 * 4 / 3 * 44

Moles of H2O = 16.3 / 3 * 11

Moles of H2O = 16.3 / 33

Moles of H2O = 0.5 moles (approx)

Therefore, along with 16.3 grams of CO2, 0.5 moles of H2O will also be formed

The total energy of an open system be changed if:

According to the First Law of Thermodynamics, energy cannot be created or destroyed, it can only change form.

An open system is a system that has an interaction with its environment where matter or energy can be added or removed from the environment.

As a result of this, the total energy of an open system can be changed if there is an exchange between matter and energy and they remain constant.

Therefore, the correct answer is an exchange has to take place for the total energy in an open system to be changed.

Explanation:

Protons

Each element has an atomic number. The atomic numbers are listed along with the names and symbols of the elements on the inside cover of the text. The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.

Different elements have different atomic numbers; therefore, atoms of different elements contain different numbers of protons (and electrons). Oxygen has the atomic number 8; its atoms contain 8 protons and 8 electrons. Uranium has the atomic number 92; its atoms contain 92 protons and 92 electrons.

The relationship between atomic number and the number of protons or electrons can be stated as follows:

Atomic number= number of protons per atom= number of electrons per neutral atom

B. Mass Number Equals Protons plus Neutrons

Each atom also has a mass number, denoted by the symbol A. The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number.

Number of neutrons = mass number - atomic number

or

Mass number = number of protons + number of neutrons

The atomic number and the mass number of an atom of an element can be shown by writing, in front of the symbol of the element, the mass number as a superscript and the atomic number as a subscript:

mass number

atomic numberSymbol of elementorA

ZX

For example, an atom of gold (symbol Au), with an atomic number 79 and mass number of 196 is denoted as:

196

79Au

C. Isotopes

Although all atoms of a given element must have the same atomic number, they need not all have the same mass number. For example, some atoms of carbon (atomic number 6) have a mass number of 12, others have a mass number of 13, and still others have a mass number of 14. These different kinds of the same element are called isotopes. Isotopes are atoms that have the same atomic number (and are therefore of the same element) but different mass numbers. The composition of atoms of the naturally occurring isotopes of carbon are shown in Table 4.2.

TABLE 4.2 The naturally occurring isotopes of carbonIsotopeProtonsElectronsNeutrons12

6C66613

6C66714

6C668

The various isotopes of an element can be designated by using superscripts and subscripts to show the mass number and the atomic number. They can also be identified by the name of the element with the mass number of the particular isotope. For example, as an alternative to

12

6C,13

6C,and14

6C

we can write carbon-12, carbon-13, and carbon-14.

About 350 isotopes occur naturally on Earth, and another 1500 have been produced artificially. The isotopes of a given element are by no means equally abundant. For example, 98.89% of all carbon occurring in nature is carbon-12, 1.11% is carbon-13, and only a trace is carbon-14. Some elements have only one naturally occurring isotope. Table 4.3 lists the naturally occurring isotopes of several common elements, along with their relative abundance.

Explanation:

I think so

There are more metals than nonmetals on the periodic table. The majority of elements on the periodic table are metals, which are found on the left and middle sections of the periodic table.

Metals typically have properties such as high electrical and thermal conductivity, luster, malleability, and ductility.

Nonmetals, on the other hand, are found on the right-hand side of the periodic table, along with the noble gases. Nonmetals generally have properties opposite to those of metals, such as poor electrical and thermal conductivity and a lack of metallic luster. There are fewer nonmetals compared to metals on the periodic table.

proof

Explanation:

Fossilized marine creatures found at the top of the Himalayan Mountains provide evidence for a scientific theory of plate tectonics. Therefore, option (D) is correct.

Plate tectonics can be explained as the Earth's lithosphere being made of a large number of tectonic plates that have been slowly moving since about 3.4 billion years ago.

The lithosphere is broken into 7 or 8 major plates and many minor plates or "platelets". These plates meet, and their relative motion evaluates the kind of plate boundary: convergent, transform, or divergent.

Mountain-building, Earthquakes, volcanic activity, and oceanic trench formation take place along these plate boundaries. The relative annual movement of the plates ranges from 0 to 10 cm.

Tectonic plates are comprised of the oceanic and the thicker continental lithosphere. The process of subduction which is actually one plate moving under another carries the edge of the lower plate down into the mantle along convergent boundaries.

Pebbles, Shells, and marine fossils found in the limestone beds of the tallest Himalayas Mountains give evidence of the theory of plate tectonics.

Given data:

Number of molecules of CO = 6.2×10²²

Mass of CO = ?

Solution:

We will use Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

For given  6.2×10²² molecules of CO mass will be,

1 mole = 6.022 × 10²³ molecules of CO

6.2×10²² molecule × 1 mole/  6.022 × 10²³ molecules of CO
