respond to these 2 questions in 100 words or more with references and in text citations. 1. In science, a measurement is collection of quantitative or numerical data that describes a property of an object or event. A measurement is made by comparing a quantity with a standard unit. Since this comparison cannot be perfect, measurements inherently […]
In your own words, answer 1 of the 3 posed questions. Then go back and respond to 2 different peers by either correcting or adding to the response with information from what you have learned in the text. Discussion responses should be on topic, original, and contribute to the quality of the discussion by making […]
Use the data format presented in the Week 1 summary for products and customers, and use the information provided in the following scenario: The number of products in the system is about 300 elements. The memory in the system is capable of holding all of the elements in the products list. The amount of products […]
For those who have a chimistry background only!! I have a chemistry lab and I am working on HPAEC. HIGH PERFORMANCE ANION EXCHANGE COLUMN. For now, You only need to write about 2 pages or 2.5 pages intro about HPAEC. I am attaching an example from another student who took this lab last semester just to give you an idea. It was about different topic […]

in 100 words or more each with references and in text citations answer the 8 questions. What are the most important intermolecular forces? And what are the mechanisms by which these intermolecular forces work? What is hydrogen bonding and how might hydrogen bonding be used to explain the substantial difference in boiling between ethanol CH3CH2OH […]
