My Teaching Style
For best comprehension, I like to divide my seession 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 theq 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 AP 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 which are covered in the AP Chemistry exam have been given out below.
Quiz : Limiting Reactants
- The most important eommercial proeess for eonverting N2 from fue air into nitrogen-containing eompounds is based on fue reaetion
of N2 and H2 to form ammonia (NH3):
N2(g) + 3 H 2(g) ----> 2 NH3(g)
How many moles of NH3 can be formed from 4.0 mol of N2 and 8.0 mol of H2?
N2(g) + 3 H 2(g) ----> 2 NH3(g)
- 8.0 mol of NH3
- 4.0 mol of NH3
- 5.3 mol of NH3
- 7.5 mol of NH3
- Consider the reaction 2 Al(s) + 3 CI2(g) ----> 2 AICI3(s). A mixture of 1.50 mol of Al and 3.00 mol of Cl2 is allowed to reacl.
Whieh is the limiting reactant?
- 2 H2(g) + O2 (g) ----> 2 H2O
Calculate the amount of water formed if 150 g of hydrogen gas and 1600 grams of oxygen gas are used in the above reaction.
- 1350 g
- 3000 g
- 1275.5 g
- A strip of zinc metal with a mass of 10.00 g is placed in an aqueous solution containing 12.50 g of silver nitrate which results in the following reaction:
Zn(s) + 2 AgNO3(aq) ----> 2 Ag(s) + Zn(NO3)2(aq)
How many grams of Ag will form?
- 33.04 g
- 7.941 g
- 33.0 g
- A factory of cars has 4000 wheels, 2200 car frames, and 2000 handlebars. How many cars can be manufactured using these parts.
About AP Chemistry Exam
AP Exam Grades
The Students scores on the free-response questions are combined with the results of the computer-scored multiple-choice questions; the weighted raw scores are summed to give a composite score. The composite score is then converted to a grade on a 5 point scale:
Use of Calculators in AP Chemistry exam.Calculators are not permitted in section I and questions based on simple calculators will be the part of section I. Programmable or graphic calculators are permitted for the entire free response exam. Calculators will not be allowed to share and calculators with type writer style (QWERTY) keyboards will not be permittted
- Big Idea 1 : Structure of matter
- Big Idea 2 : Solids , Liquids and Gases
