Today’s goal . Identify quantities in a given situation. Define variable to quantities in a given situation. Write a formula using variables for a give situation. In the first investigation we learned that it. (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Lecture 1 – Thursday 1/10/2013. 2. Introduction. Chemistry 3/18/19. Drill. Write down these questions. While watching the video clips, write the answers, and when done, discuss with your row:. Why is airbag use in cars important?. What is the chemistry involved in air bag inflation?. (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Lecture 1 – . Thursday. 2. Introduction. Definitions . (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture 1. 1. Lecture 1 – . Thursday. 2. Introduction. Definitions . Diagnosis and evaluation of postmolar GTN. Case Scenario . A 21 year old . nulligravida. presents with bleeding during early pregnancy. Last normal menses was 9 weeks ago, home urine pregnancy test was positive 2 weeks ago, and she has been spotting for two days with heavier bleeding the last 6 hours.. Avogadro Memes…. MOLE. (mol)‏. Mass. (g)‏. Particles. (. atoms,m’c. or . f.u. .). MOLE CONVERSIONS. Which conversion factors allow you to convert from mass to moles and from particles to moles.. Atomic mass. Atoms of different elements have different masses. . Mass of a single atom is incredibly small so a special unit called atomic mass unit (. amu. ) is used. . Atomic Mass. Atoms are composed of three particles:. big. concepts of Chemistry.. The mole is a . counting. number, just like. 1 dozen = . 12. things . 1 score = . 20. things . 1 ream = . 500. things . 1 mole = . 6.022 x 10. 23. . things or . Chapter Objectives. Describe the chemical processes used in biomass production and conversion to biofuels.. Explain balancing a chemical reaction as an application of the . law of conservation of mass. 23 . particles. . So a “mole” is a number, very similar to a dozen. . A dozen = 12 . A mole (mol) = 6.022 x 10. 23. It can be found in your reference packet on page one. Avogadro’s number = 6.022 x 10.
