In some occasions, you will have to write an essay in the extremely short amount of time on the exam in college or high school. Also, you may be a little bit of a procrastinator, and find yourself in a situation when the paper is due tomorrow morning, and you have not even chosen the topic yet. Even though a last-minute essay cannot look as great as a work prepared successively and carefully within the whole time given, you still have a chance to submit a decent paper. The working process will require your full attention and a lot of effort, even if you are assigned a simple essay. However, if you learn the next few tips, the essay writing will seem significantly easier and feasible even when you are short on time.

Firstly, clean up your working space to get started. Make sure you have everything you need on the table, take a pen, a few sticky notes, your laptop, and read through the assignment requirements. In case no prompt is given, search for good essay topics, and pick a few uncommon and interesting ones you will be able to write about. Making a final choice, think which topic is the most relevant to your current studies and will not take too much to research.

Afterwards, look for the most trustworthy sources or the ones you are certainly allowed to use. If you are not sure, access the online library or any free services where you can look for the books and articles for your essay. Use sticky notes to write down the information and put them in front of you to see how much data has been gathered and if you need to continue researching. Reread these notes from time to time and cross out the info you do not find relevant anymore.

When you have the data you need to produce a quality work, it is crucial to think about the structure of the future paper. If you are not sure how to write an essay outline properly, check what your essay type is first. Each type is organized differently, so you need to look up the structure every time you are given an essay homework. You can also search for an example of the essay on your topic, and adhere to its outline. No matter what kind of essay you are going to write, it is important to start with a thesis statement. It should declare what problem you will review in the paper, and which facts or arguments you will use to do it professionally. As these arguments will be discussed in the main part of the essay, outline the body paragraphs and put down a few sentences with the rough description of each paragraph. Think of the way you will engage the reader in the introduction, and which thought will be conclusive for the paper. When the direction of the work is clear from the outline, use it to draft the first version of the essay.

If you are not used to model essay writing, do not worry - your draft should not necessarily look like a masterpiece. It is only the depiction of your thoughts, and as you will have them written down, it will be easier to create a good essay. There is no best way to write an essay, so trust the working methods you usually use. You may like taking short breaks once in a few minutes, or write everything in one sit - just make sure to keep the focus on writing and avoid the urge to call a friend or watch something online. Thus, you will finish the paper faster, and will not feel guilty for engaging in other activities afterwards.

Do not forget to go through the essay a few times after the completion. Everyone makes typos and mistakes by accident, but it is about you to find and fix them before your teacher does. If you need help with an essay editing, try asking a friend or a family member to read and analyze your work. Also, you can order editing services in case your paper needs to be perfectly polished so that you can submit an ideal essay and get an excellent grade.

As these steps are simple to follow, you will not have any problems coping with an essay on time. Try the whole procedure at least once, and you will not have to use any other tips preparing an essay paper during your studies!

What is the molecular geometry of selenium tetrafluoride?

The molecular geometry of SeF4 is see-saw and electron geometry is trigonal bipyramidal, this is because the selenium central atom has one lone pair on equatorial position and 4 bonded pairs are attached to it.

What is the formula of selenium tetrafluoride?

SeF4Selenium tetrafluoride / Formula

What is the formula of selenium Tetrabromide?

SeBr4Selenium tetrabromide / Formula

What is the correct name for SeF6?

Selenium hexafluoride
Selenium hexafluoride | SeF6 – PubChem.

Why is SF4 trigonal bipyramidal?

The SF4 molecule has a bipyramidal trigonal geometry shape because it contains four fluorine atoms. There are four S-F bonds at the SF4 molecular geometry. After linking the four fluorine atoms in the bipyramidal trigonal form, it maintains the trigonal bipyramidal-like structure.

Is SiF4 tetrahedral?

The SiF4 molecule has a tetrahedral shape because it contains four fluorine atoms. There are four Si-F bonds at the top of the tetrahedral geometry.

What is TeBr2 in chemistry?

Tellurium bromide (TeBr2)

What is the shape of the molecule selenium tetrachloride?

Seesaw
Selenium tetrachloride

Names
Crystal structure Monoclinic, mS80
Space group C12/c1, No. 15
Molecular shape Seesaw (gas phase)

Is SeBr4 a polar molecule?

Why? Well if SeBr4 ends up square planar like IF- above or tetrahedral like CCl4, the Se-Br dipoles will cancel vectorially to a zero dipole moment, and the molecule won’t be polar.

Is sef6 a octahedral?

The molecular geometry of SeF6 is octahedral with symmetric charge distribution on the central atom. Therefore this molecule is nonpolar.

Does sef6 exist?

Selenium hexafluoride is the inorganic compound with the formula SeF6. It is a very toxic colourless gas described as having a “repulsive” odor.

Why the shape of SF4 is seesaw?

Trigonal bipyramidal (sp3d) is the shape of SF4 with one equatorial position occupied by 1 lone pair. It has a see-saw shape as it contains four bond pairs and one lone pair. The equatorial F atoms are 120 from each other., so the axial/equatorial bond angle is 90 degrees. Was this answer helpful?

What is selenium tetrafluoride?

Selenium tetrafluoride is a selenium coordination entity. Copyright © 2002-2021 Wiley-VCH Verlag GmbH & Co. KGaA. All Rights Reserved. Copyright © 2002-2021 Wiley-VCH Verlag GmbH & Co. KGaA.

What is the bond angle of selenium and fluorine?

The two other fluorine atoms are attached by shorter bonds (168 pm), with an F-Se-F bond angle of 100.6°. In solution at low concentrations this monomeric structure predominates, but at higher concentrations evidence suggests weak association between SeF 4 molecules leading to a distorted octahedral coordination around the selenium atom.

What is the structure of selenium in SeF4?

Structure and bonding. Selenium in SeF 4 has an oxidation state of +4. Its shape in the gaseous phase is similar to that of SF 4, having a see-saw shape. VSEPR theory predicts a pseudo-trigonal pyramidal disposition of the five electron pairs around the selenium atom. The axial Se-F bonds are 177 pm with an F-Se-F bond angle of 169.2°.
