given the following equation N2(g)+3H2(g)=2NH3(g) determine to one decimal place the molar mass of each substance and express each mass in grams per mole
The explosive, trinitrotoluene, TNT, C6H3N306, has the same proportion of: a. N to H atoms as does NH3 b. H to O atoms as does H20 c. N to O atoms as does NO2 d. C to H atoms as does C3H6 e. C to O atoms as does CO2. I know the correct answer is C. But I need someone to help explain how to do this problem for me. Thanks!
As you learn to view the world through a chemistry lens, it will become important for you to learn to use the language of chemistry. There are some challenges associated with chemistry vocabulary because many of the words that are used in a technical sense in chemistry might also be used in everyday language. However, the meanings of the words in the two contexts can be very different. In the discussion questions for this course, we will practice using these terms and becoming comfortable with going back and forth between their everyday and technical meanings. This week, consider the following terms: Element Compound Molecule Density Precision Accuracy Respond to the following in a minimum of 200 words in APA format: Choose at least 2 terms from the list, and answer the following questions for each term: What familiarity and prior knowledge do you have about the term? What does the term mean in everyday language to everyday people? Use examples to help describe your thoughts. How do people use the word? What does the term mean in technical language to chemists? How is the term related to the course student learning outcome: Explain matter at the microscopic level? What are the similarities and differences between the everyday and technical meanings and uses of the term? What impact might the similarities and differences have on your learning of chemistry concepts in this course?

Describe the process of vinegar production. Include which genera of bacteria are commonly applied, a schematic of the catabolic pathway, types of reactors used in production and post-processing
Please reply to the following discussion. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Responses must consist of at least 125 words, do NOT repeat the same thing your classmate is saying. No reference required. M.V. Isotope and Atomic Theory Both the terms isotope and atomic theory are not super familiar to me. They sound vaguely familiar due to high school chemistry class several years ago but otherwise these are not words that are seen in my daily life. In everyday language these words mean nothing to me. I do not use nor do I hear other people use these vocabulary words from day to day however in the technical language of chemists, an isotope is defined as atoms of the same element but differing in mass. The reason for this difference in mass is due to having a different number of neutrons even thought they have the same amount of protons, which technically make them chemically the same element. Isotopes were first discovered in the early 1900s by a chemist who was awarded the Nobel Prize as a result of his findings. The other term, atomic theory is composed of several different postulates of Joh Dalton. These hypothesis in a total of five together give a microscopic explanation of many macroscopic properties of matter. Both of these terms are related to the course learning outcome because we are learning to explain matter at a microscopic level. The composition of Isotopes literally have us explaining the matter elements at a microscopic level. Atomic theory helps us define and explain matter at the macroscopic level. But in order to understand matter at the macroscopic level, we need to have an understanding at the microscopic level. Dalton’s atomic theory explains outcomes of the microscopic level of matter by the outcome of the macroscopic level of matter. There are not similarities for these terms used in everyday language versus in chemist’s technical language because I am not familiar with these terms used in day to day language at all. Because of this, there is no impact on my understanding of these words. It is almost as if I have a clean slate and can base my understanding from the true definition of these terms.
