Write the balanced chemical equation for the reaction taking place in the flasks for part 1.  From the mass of KHP, calculate the moles of KHP used for each of 3 trials.  Using the moles of KHP in each flask, use stoichiometry to calculate the moles of NaOH that were used to reach the equivalence point in each flask.  Finally, calculate the molarity of your […]

Create an Outline Lab Report. This report will contain a title and the 5 elements of a lab report: Abstract, Introduction, Methods/Materials, Results, and Discussion. Our outline is going to be compiled of questions, instead of information. I understand that some of them might be repetitive, especially for Title and Introduction, and that’s ok. So for the 6 items I have listed above, you will […]

 Profit this really is open to the actual candidate within 2 through guaranteed as well as unsecured. Candidate who’re posing a few home within their title as well as can publish any kind of protection from the cash they are able to choose the actual guaranteed type of availing the actual money. Just in case anybody that cannot publish any kind of security from the […]

Please select one of the topics below and prepare a well-organized and thoughtful summary for your research paper. The  topic chosen should expand on what you are learning during this course. Show how you understand the issues with life  experiences from the fire service. A title page, table of contents, and reference page are required, but are not included in  the assignment’s required page count.  […]

To most people, a polymer is synonymous with plastic. Technically, there are many different types and uses of plastic. For this discussion board, let us narrow it down to plastic food containers. The most popular or controversial issue that has come up to date is regarding BPA (bisphenol A). BPA is a monomer in some plastics, including polycarbonate. For consumer safety, products must undergo a […]

Write a research paper about one element from the periodic table of the elements. Select an element that you find interesting and tell the story of that element. In doing so, explain how the element relates to the elements around it in the periodic table and why the element is in that particular location on the table of elements. Below is a list of aspects […]

Scientist can use telescopes to look at stars billions of light years away.  Using the ‘images’ they gather from stars and planets, scientists are able to determine the size, temperature and mass of the star or planet.  Also, they can determine the chemical composition, specifically if there is water and organic (carbon-based) materials.  The technology required to do this goes well beyond your typical Wal-Mart […]

This week you will be in a discussion group of three students. Each student will explain and teach the others how to solve one of the three problems below.  All three problems must be answered; decide among yourselves who will answer each question. You may present your lesson by typing your answer (although typing equations can be difficult), writing on a piece of paper then […]

A plant manufacturing nails and screws uses a large pool (volume = 10,000 L) to collect and treat its residual waste water before discharging it in a nearby stream.  The manufacturing process makes use of a strong acid (HCl) and a weaker one (phosphoric acid, H3PO4; pKa1 = 2.148, pKa2 = 7.20, pKa3 = 12.15), before discharging them in the pool for treatment (neutralization).  Once […]
