PPT-Balancing equations and reacting masses

Balancing equations and reacting masses Objective To know how to balance equations and how they can be used to calculate masses of reactants needed and products made Outcomes Write full balanced symbol equations. Reacting to the Past courses employ a di fferent pedagogy Students learn by taking on roles informed by classic texts in elaborate games set in the past they learn skills speaking writing critical thinking problem solving leadership and teamwork in HIGHER LESSON.

Balancing Chemical Equations. Can’t Create or Lose Atoms. I can identify the products and reactants in a chemical reaction.. I can state the law of conservation of matter.. I can determine the number of each atom in a compound based on subscripts and coefficients.. Can’t Create or Lose Atoms. A. B. A. B. A. B. 2A + 2B . . AB. Not Balanced. You must have the same number of each type of atom on each side of an equation.. Balancing Chemical Equations. Can’t Create or Lose Atoms. 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. To to Balance the Elements. Equation. Product. Reactant. Mass. Balanced.
