Chemistry: How to do number one to seven?(Dalton’s Law)WS 6.5 Partial Pressures (Dalton’s Law)don’t forget unitsp = (mol frac) x (P)1. A flask contains Ne at 542 mmHg together with Ar at 234 mmHg. What will the total pressure be?use Dalton’s law)Ans2. A tank is filled with oxygen and nitrogen. The total pressure of the tank is 6.45 atm, and the partialpressure of the nitrogen is 2.07 atm. What is the partial pressure of the oxygen? (use Dalton’s law)Ans3. a) A mixture contains 1.00 moles of CO2, 2.00 moles He, and 3.00 moles of CH4. Which gashas the highest partial pressure?Which gas has the lowest partial pressure?b) If the total pressure of the mixture above is 12.0 atm, what is the Pco2?PHe?PCH4?4. a) 1.25 moles of N2 and 6.41 moles of F2 are placed together in a 128 L tank at 755 mmHg. Whatis N2’s mole fraction in the mixture? What is the partial pressure of the N2?a) Ans:b) What is F2’s mole fraction, and what is the partial pressure of the F2?b) Ans:c) What must the temperature ("C) of the mixture be?Ans5. a) 3.23 g of Ne and 4.19 g of CH4 are placed together in a tank at 5.34 atm and 23*C. What isNe’s mole fraction, and what is the partial pressure of the Ne?a) Ans:b) What must the volume of the tank be? (use ideal gas law)Ans6. A tank contains 5.86 g of Ar and 5.77 g of Ne. The partial pressure of the Ar is 237 mmHg. Whatis Ar’s mole fraction and what is the total pressure of the tank?Ans:7. A flask contains 2.34 x 1022 atoms of He, 0.1972 moles of CO2, and 2.45 g of N2.

Frequently asked questions
Is your service confidential?

When you place an order with our company, we ask you to provide us with such personal information as your name, phone number, and email address. We need this data to keep you updated on the important things related to your order or account.

Is there a possibility of plagiarism in my completed order?

We complete each paper from scratch and in order to make you feel safe regarding its authenticity, we check it for plagiarism before its delivery. To do that, we use our in-house software, which can find not only copy-pasted fragments but even paraphrased pieces of text. Unlike popular plagiarism detection systems that are used by most universities (e.g. Turnitin.com), we do not report to any public databases—therefore, such checking is safe.

We provide a plagiarism-free guarantee that ensures your paper is always checked for its uniqueness.

Is there a money-back guarantee? If yes, how can I receive a refund?

You can certainly get your money back in several cases. You can receive a full refund if you have paid for your order twice or if you have placed two identical orders. In case your paper was late or the quality of the paper does not correspond to your expectations, you will get compensation for these issues.

Do you keep a database of pre-written essays?

No, we do not have such a database. All papers you order from us are written from scratch. This means your paper is unique and has never been published before—neither will it be published after we deliver it to you.

 

When will my custom paper be done?

While placing an order with WritersHub, you can choose a period of time within which a paper should be delivered to you. The countdown until the specified deadline starts automatically from the moment we receive your payment in our system. For example, if you pay for your order at 6pm on Monday and choose a 3-day delivery option, you will receive your custom paper by 6pm on Thursday.

Remember that a writer needs a sufficient amount of time in order to conduct thorough research. Therefore, please choose the most suitable deadline when you place an order. Moreover, the later you need your paper to be delivered to you, the cheaper it will be. Thus, you will be able to save your money while your writer will have enough time to work on your order and ensure its quality.

Make sure you upload all the additional materials at the very beginning. If you fail to do that, the deadline for your order will be postponed as well.

I haven’t received my custom paper by the deadline. What should I do?

Let us know immediately about that. You can do it by writing a message on Facebook or email us. Our support manager will carefully examine your order and will assist you with it right away. The reasons for late delivery may vary from time to time. It can happen that you have entered a wrong email address or your spam filter does not allow you to receive emails from us. It is also possible that the writer is waiting for your reply and can not continue working without your assistance, or we are checking the work for plagiarism. Whatever the case may be, contact us if you have any problems with getting your order on time.
