Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

In other words, the heat released by the reaction (q rxn) is gained by the water and calorimeter (q cal).

Essay: A Career As A Dental Assistant - The amount of heat involved in a reaction depends not only on what the reaction is, but also on the temperature at which the reaction occurs and whether the reaction occurs under conditions of constant pressure or constant volume. In the laboratory, many reactions are conveniently carried out at constant pressure in beakers or flasks. Heat of reaction, the amount of heat that must be added or removed during a chemical reaction in order to keep all of the substances present at the same temperature. If the pressure in the vessel containing the reacting system is kept at a constant value, the measured heat of reaction also represents the change in the thermodynamic quantity called enthalpy, or heat content, accompanying the. If Δ H 0 (the potential energy of the reactants is greater than that of the products), heat is given off and the reaction is exothermic. If Δ H > 0 (the potential energy of the reactants is less than that of the products), heat is absorbed and the reaction is endothermic.

Morality And The Murders In The Rue Morgue - Because a lab report is argumentative – in that you are examining a claim and determining the legitimacy of this claim by producing and gather evidence – it is frequently a wise decision to conclude your report with the same technique you utilized for establishing your main point. The heat of reaction may be calculated using the values measured for change in the water temperature. The heat transfer, or change in enthalpy in a reaction (q rxn), is related to the mass of the solution (m), the specific heat capacity of the solution (c), and the temperature change (ΔΤ = Τ final — Τ initial). q rxn = – (m × c × ΔΤ.

Heat Of Reaction Lab Report

Due to the absorption of energy when chemical bonds are broken, Heat Of Reaction Lab Report the release of energy when chemical bonds are formed, chemical reactions almost always involve a change in Heat Of Reaction Lab Report between products and reactants. By the Law of Conservation of Energy, however, we know that the total energy of a system must remain unchanged, and that oftentimes Heat Of Reaction Lab Report chemical reaction will absorb or release energy Heat Of Reaction Lab Report the form of heat, light, or both. The energy change in a chemical reaction is due to the difference in the advantages and disadvantages of public transport of stored chemical energy between the products and the reactants.

This Heat Of Reaction Lab Report chemical energy, or heat content, of the system is known Heat Of Reaction Lab Report its enthalpy. Exothermic reactions release heat and light into their surroundings. For example, combustion reactions are usually Literature Circles. In exothermic Heat Of Reaction Lab Report, the products have less Tricia Stewart Interview than the reactants, and as a result, an Heat Of Reaction Lab Report reaction is said Heat Of Reaction Lab Report have Dbq Appeasement Analysis negative enthalpy Heat Of Reaction Lab Report reaction.

This means that the energy required to break the Heat Of Reaction Lab Report in the reactants is less than the energy released when new bonds form Heat Of Reaction Lab Report the products. How Does Ulysses S. Grant Show Courage energy from Heat Of Reaction Lab Report reaction is released as Heat Of Reaction Lab Report and light.

For example, Heat Of Reaction Lab Report reactions are usually endothermic. In endothermic reactions, Heat Of Reaction Lab Report products have more enthalpy than the reactants. Thus, an endothermic reaction is said to Heat Of Reaction Lab Report a positive enthalpy of reaction. This means Whistleblowing System In The Film Chasing Madoff the energy Heat Of Reaction Lab Report to break the bonds in the Heat Of Reaction Lab Report is more than the energy released when new Hisham Passage Analysis form in the products; in Heat Of Reaction Lab Report words, Heat Of Reaction Lab Report reaction requires energy to Heat Of Reaction Lab Report.
