My Teaching Style
For best comprehension, I like to divide my session into two parts:
Teaching Using Digitized ContentI use my own training content which has been specially prepared keeping the needs of students in mind. I focus upon clearing the basics of the subject first before moving on. Detailed explanations provided in a easy to understand manner forms the key to understanding.
Chemistry QuizzesAt the end of each session I go over thew quizzes on the topic with the student which ensures correct assimilation by the student and any gaps in knowledge that may be there are clarified. I also provide Chemistry Quizzes for IB Chemistry Exam which students can attempt in their own time and discuss with me during the sessions. Please feel free to Contact Me for any clarifications.
A sample presentation and its associated quiz is given below. Please feel free to go over the presentation and attempt the quiz.
Study TopicsThe study topics as per the IB Chemistry Syllabus have been given out below.

- 100 cm3 of 0.05 mol dm−3 CuS
- 100 cm3 of 0.20 mol dm−3 CaCl2
- 50 cm3 of 0.40 moldm−3 RbCl
- Formation of polyethene from calcium carbide, CaC2, can take place as follows:
CaC2 + 2H2O → Ca(OH)2 + C2H2
C2H2 + H2 → C2H4
nC2H4 --> -(-CH2 - CH2 -)n -
What mass of polyethene is obtained from 100. kg of CaC2 ?
- 43.8 kg
- 14.5 kg
- 28 kg
- 21 kg
- The percentage by mass of the elements in a compound is
C = 52.2%, H =13%, O =34.8%.
What is the mole ratio of C : H in the empirical formula of this compound?
- 6 : 1
- 1 :3
- 1 : 6
- 1 : 2
- What is the minimum number of grams of O2 (molar mass = 32 g/mol)required to burn 1.5 grams of C2H6(molar mass = 30.0 g/mol)according to the equation below?
C2H6+7/2 O2 -->2CO2 +3 H2O
- 10.0 dm3 of sulfur dioxide is reacted with 6.0 dm3 of oxygen according to the equation below.
2SO2(g) + O2(g) → 2SO3(g)
What volume of sulfur trioxide (in dm3) is formed?
IB Chemistry Exam
Assessment in the IB Chemistry exam is by means of examination and practical for both higher and standard level chemistry courses.

Paper 2 (High Level) : Duration - 2 hours 15 minutes. The paper consists of five structured questions and a choice of two from four longer answer questions. Calculators are allowed and a data booklet is provided
Paper 3 (High Level) : Duration - 1 hour 15 minutes The paper consists of three questions form each of two selected options. The paper presents eight option choices. Calculators are allowed and data booklets are provided.
Examination (Standard Level)
There are three papers:
Paper 1 (Standard Level) : Duration - 45 minutes The paper consists of 30 multiple choice questions. Calculators are not allowed. A periodic table is provided
Paper 2 (Standard Level) : Duration - 1 hours 15 minutes The paper consists of some structured questions and a choice of one from three longer answer questions. Calculators are allowed and a data booklet is provided
Paper 3 (Standard Level) : Duration - 1 hour The paper consists of two questions from each of two selected options. The paper presents eight option choices. Calculators are allowed and data booklets are provided.
The final grade awarded for an IB subject is from 1-7. The schools receive a breakdown of the grade achieved in each part of the exam.
