Edexcel 9-1 Combined HIGHER Chemistry Calculations Revision LESSONS (TOPIC 1 KEY CONCEPTS)

CAN BE USED FOR ABOUT 5 LESSONS

OVER 140 SLIDES

ACTIVATE - SHOWING THE FORMULA AND HOW IT WORKS

DEMONSTRATE - ALLOWING STUDENTS TO COMPLETE THE QUESTIONS

AFL - CHECKING ANSWERS (ALL ANSWERS PRESENT)







Edexcel CC9 PART 1-3 Calculations involving masses for the new 9-1 GCSE



3-4 lessons depending on how good student are at the calculations

Mainly covering

TOPIC 1 KEY CONCEPTS OF CHEMISTRY PAPER 1 and PAPER 2- NEW for SEPTEMBER 2017

Touching on TOPIC 7 Bond energy calculations for the higher tier students



A mock exam will be give after this batch of lessons - something different when you start revision

FOR THE MOCK I USED SEE

IT IS FREE



Powerpoint with over 130 slides including worked examples, questions for the students to complete and then the answers of the questions.

Some calculations include more than one method, to help stretch the brightest and support the lowest ability students.

There is a summary slide for each paper (Paper 1 and Paper 2) and a calculations summary slide to show all the equations that students will need to know.





QUESTIONS ATTACHED TO ALLOW STUDENTS TO WORK INDEPENDENTLY OR AT THEIR OWN PACE (THEY ARE THE SAME QUESTIONS AS IN THE POWERPOINT - SO ALL ANSWERS ARE IN THE POWERPOINT) Can set as homework or use in a revision lesson.



Calculations include:

Rf Value

Isotope Calculation (H)

Relative Formula Mass

Empirical from molecular

Molecular Formula from Empirical Formula and Mr

Empirical Formula from Reacting masses and % composition

Conservation of Mass

Reacting masses (without moles)

Concentration (g/dm3)

Moles (H)

Using Avogadro’s constant to calculate the number of atoms or molecules (H)

Reacting masses (with moles) (H)

Finding the Limiting Reagent (H)

Using the limiting reagent to calculate the mass (H)

Balancing equations (with moles) (H)

Bond Enthalpy (H)
