PPT-Mole Review 1.) Calculate the number of moles in 60.4L of O

2 2 How many moles are there in 632g of Cl 2 604L O 2 224L O 2 1 mol O 2 27 mol O 2 632g Cl 2 70g Cl 2 1mol Cl 2 0903mol Cl 2 Ch 9 Math In Chemistry. HIGHER LESSON. Learning Objectives. To . explain. what chemical equations tell us about chemical reactions. To . explain. how we use equations to calculate masses of reactants and products. HIGHER LESSON. Hi I'm Malcolm the mole. habitat. . You might have seen my house roof but there is a little Chance of you seeing me or other . moles. because I live Under the ground . You can find moles in woodland, grassland and farmland And all around the U.K. If you find a mole hole don’t kick it down because The moles babies are under there.. They tell us how much of each substance is involved in a chemical reaction. 2H. 2. + O. 2. .  2H. 2. O. 2 moles of hydrogen react with 1 mole of oxygen to make 2 moles of water. This is useful because now we can use it to work out what mass of hydrogen and oxygen we need and how much water is made. 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?. 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 . 1 mole of a substance is 6.02 x 10. 23. . representative particles. .. Avogadro’s number = . 6.02 x 10. 23. Avogadro determined the difference between atoms and particles.. Representative particle. Use . the coefficients to predict the amount of reactant consumed or product formed. The ratio of the coefficients is a ratio of the moles taking part in a reaction.. Reactants (on the left of the arrow) are consumed. 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. 2. O. 3. ) . C/W. 23/09/2020. 3.2.1. Ar of Al = 27. Mass of Al in Al. 2. O. 3. = 27 x 2 = 54. Mr of Al. 2. O. 3. = (27x2) +(16x3) = 102. Percentage of aluminium = 54/102 x 100 = 52.94%. Progress Outcomes. 2 C. 4. H. 10. + 13 O. 2. ---> 8 CO. 2. + 10 H. 2. O . Show . what the following molar ratios should be.. a. . C. 4. H. 10. / O. 2. . 2:13. b. O. 2. / CO. 2. c. O. 2. / H. 2. O. d. C. 4.
