Description Please complete the attached lab report template and use all of the data and experiment details attached to complete the report in its entirety. Everything you should need are in the attached files.
Description This criterion is linked to a Learning Outcome Responses to worksheet questions Each lab worksheet will have a number of questions to complete. On various worksheets you may be asked to: provide answers to open-end questions, create outlines, fill in blanks, or complete tables. Be sure to provide complete answers to each question and to fill all blanks and tables as appropriate for each assignment. Each question or blank will be worth 1 pt as a raw score. Different worksheets will have different raw scores depending on the length of the assignment. Your instructor will then convert your raw score to a point value out of 10 based on your performance on each worksheet.
Description Hello, I need all parts of this project completed. Please follow the directions given and complete this project correctly. I will be attaching the project as well as the textbook pages needed to complete this project. Thank you!
Description D. The Balmer Series 1. When Balmer found his famous series for hydrogen in 1886, he was limited experimentally to wavelengths in the visible and near ultraviolet regions from 250 nm to 700 nm, so all the lines in his series lie in that region. Based on the entries in Table 2 and the transitions on your energy level diagram, what common characteristic do the lines in the Balmer series have? What would be the longest possible wavelength for a line in the Balmer series? ? = ___________nm What would be the shortest possible wavelength that a line in the Balmer series could have? Hint: What is the largest possible value of ?E to be associated with a line in the Balmer series? ? = ___________nm The Ionization Energy of Hydrogen 1. In the normal hydrogen atom the electron is in its lowest energy state, which is called the ground state of the atom. The maximum electronic energy that an electron in a hydrogen atom can have is 0 kJ/mole, at which point it would essentially be removed from the atom and it would become a H+ ion. How much energy in kilojoules per mole does it take to ionize a hydrogen atom? ______________ kJ/mole The ionization energy of hydrogen is often expressed in units other than kJ/mole. What would it be in joules per atom? in electron volts per atom? (1 ev = 1.602 x 10-19 J) ______________J/atom; _____________ ev/atom
Description - What mass of water, in grams, would have to be decomposed to produce 28.3 L of molecular oxygen at STP? - If a gas has a volume of 5.2 L at a temp of 24 Degrees Celsius and a pressure of 3.3 atm, how many moles of gas are present - What volume (in liters) does 30 g sample of Neon (Ne) gas occupy at standard conditions (STP)?
Description Unit 1: Atoms and The Periodic Table Unit Project For this unit project, you will be conducting more research. Pay special attention to presenting your evidence. Each fact needs to be introduced, stated, cited, and interpreted. Your research needs to include both your textbook and outside resources such as books or websites. Your applications throughout this unit prompted you to write about the concepts that you will cover in this unit project. Begin by reviewing your applications and any teacher responses you received. You need at least two resources besides your textbook, although more will lend strength to your argument. Make sure that your sources are credible! Wikipedia will not be acceptable for this project. As always, include supporting examples for your claims, and quote and cite throughout your paper. For this Unit Project, plan your own research method. Here is the prompt you will address: Explain the development of atomic theory and periodic table. Your audience should be an imaginary classmate - someone who has a surface-level knowledge, but has not studied this topic deeply. Click on the link in the Red Box to view the Project Rubrics for this project. Some points that you should consider as you are researching and composing your paper are: Who were the scientists who were key figures in the development of atomic theory? Who discovered which parts of the atom? How did these scientists develop their model of the atom? Explain disagreements between scientists and their models. Explain how atoms were organized into the periodic table. These points should all be addressed in the body of your paper. This paper should be informative in tone and purpose, and should not include your opinion. In the conclusion of your paper, discuss the significance of this information. How does this history show us the importance of self-correction within the scientific method? Also, why is the atomic theory important to an average person's daily life? Your paper should be between 750-1250 words (3-5 double-spaced pages). You must include a Works Cited page (including the textbook and two credible outside resources) as well as in-text citations. In addition to your paper, you must include a short writer's reflection. In this reflection, describe your research process. How do you find resources? How do you determine if a resource is reliable? How do you tell the difference between primary and secondary sources? How do you take notes? What sort of technology or organizational tools do you use to keep your notes organized? What steps do you use to avoid plagiarising accidentally? This reflection must be included after the Works Cited page within the same document as your essay. This is an informal piece that should address all the questions, but does not need to be academic in tone. It should be between 100-200 words
