Gas stoichiometry deals with reactions involving gases, where the gases are at a known temperature, pressure, and volume and can be assumed to be ideal gases. For gases, the volume ratio is ideally the same by the ideal gas law, but the mass ratio of a single reaction has to be calculated from the molecular masses of the reactants and products.Notes on this topic.

CHAPTER 7: Redox Reactions and Electrolysis. CHAPTER 8: Chemical Equilibria.Step 1: Write the balanced equation for the reaction. Step 2: Write down the relative atomic mass (A r) and the relative molecular mass (M r ), for each substance in the equation. Step 3: Using A r or M r, change the moles in the equation to grams. Step 4: Find the actual masses.The Mole Concept. A mole of a substance is the amount that contains the same number of units as the number of carbon atoms in 12 grams of carbon-12. A mole is the A r or M r expressed in grams e.g. 1 mole of Carbon-12 is equal to 12 grams. It is equal to 6.02 × 10 23 particles, this number is called Avogadro’s constant. An instrument called a mass spectrometer is used to calculate relative atomic mass. In a mass spectrometer, atoms are converted to positive ions; these are then deflected by electric and magnetic fields before being detected. The mass of the elements individual isotopes are found as well as their abundance.The stoichiometry of a balanced chemical equation identifies the maximum amount of product that can be obtained. The stoichiometry of a reaction describes the relative amounts of reactants and products in a balanced chemical equation. A stoichiometric quantity of a reactant is the amount necessary to react completely with the other reactant (s).Download File. Exercises-acknowledgements.doc. File Size: 53 kb. File Type: doc.

The theoretical yield of 100 g is the calculated amount of product, assuming that the reaction is 100% efficient. The percentage yield is the ratio of actual yield to theoretical yield expressed as a percentage: (37 g/100 g) × 100% = 37%. 3.IGCSE CHANGES STATES OF MATTER PART 2 Watch on What is necessary to change one state of matter into another?
