Acids and Bases. Neutralization reactions and titrations

From 25 C$ /h

Acids and bases is a division of chemistry that involves the classification of acids and bases and the different reactions that involve acids and bases. I have designed the lessons in a systematic way that enhances understanding. You will learn how to write balanced chemical equations for the reactions between acids and bases. You will also learn how to figure out the suitable indicate for any given titration. You will learn more about the pH scale and the calculations for determining the pH of a given solution. You will also learn the hydrolysis of a salt and the calculations of determining the pH of a salt solution.

Stoichiometry, calculations of percentage purity and percentage yield, determining the excess and the limiting reactant

25 C$ /h

Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist between the reactants and products in chemical reactions. I have designed the lessons in a systematic way that enhances understanding. You will learn how to calculate the amount of product that is going to be formed when you are given the amount of reactants and the yield. You will learn how to use balanced chemical equations and molar rations to figure out the excess and the limiting reactants. You will also learn how to calculate percentage purity of the reactants and percentage yield of a given chemical reaction.

Electricity, Electric current, voltage, and resistance. Electric circuits

25 C$ /h

Electricity is a division of physics that involves the flow of charges in a conductor. The three variables that are essential in electricity are voltage, electric current and resistance. I designed the lessons in a systematic way that enhances understanding. You will learn how apply Ohms law to calculate one variable given the other two. You will learn how to do electric circuit calculations that involve series, parallel and hybrid circuits.

I hold a PhD in Mechanical Engineering and currently work as a post-doctoral researcher in the Aerospace Engineering Faculty at TU Delft (Delft University of Technology).

My extensive teaching experience covers a wide range of engineering courses, including:

- Mathematics: algebra, linear algebra, probability, calculus, differential equations, intellectual math, and advanced engineering mathematics.

- Mechanical Engineering: Statics, Dynamics, Mechanics of materials, Mechanical design, control, vibration, Fluid Mechanics, Thermodynamics, Heat transfer, Engineering drawing, Applied Mechanics, Composite Structures, Flight, Machine Elements, Manufacturing, 3D printing, and more.

- Physics: mechanics, momentum and energy, electricity, charge and current, electric and magnetic fields, waves, particle physics, nuclear decay, astrophysics, cosmology, oscillations, etc.

- CAD/CAM Software: Autocad, Solidworks.

- Mechanical Design Packages: ANSYS, APDL programming, ABAQUS, MATLAB, Symbolic MATLAB, LS-DYNA.

My research and teaching interests are diverse, including:
• Additive manufacturing
• Mechanical metamaterials
• Acoustical metamaterials
• Electromagnetic metamaterials
• Aeroacoustics
• Soft matter and soft robotics
• Fatigue and fracture mechanics
• Experimental mechanics
• Multiscale numerical modelling
• Biomaterials

I understand that not all teachers excel in teaching Engineering and Mathematics courses and explaining their importance to students. Courses with strong mathematical backgrounds may become boring for students who lack a solid mathematical basis. To address this, I take a student-centered approach, starting from the basics to actively engage all students, including those with weaker mathematical backgrounds. I also provide practical examples to demonstrate the real-world significance of what they are learning, inspiring and fostering their interest in the subject matter.

If you have any additional questions before starting a class, please feel free to ask me. I am here to assist! :)

If you're looking for an organised and professional teacher to help you achieve your academic goals, look no further! The IB science subjects can be extremely difficult to go through on your own, and I'll be glad to use my experience to help you out.

A couple of things I like to do:

- Initial test or interview to assess your level.
- Use Notion as a platform to share all my resources.
- Use mock papers that lay out the exercises JUST like in the real exams, so you will feel really prepared.
- I give homework when appropriate.
- I provide any kind of mentoring and college counseling. People who study Biology and Chemistry usually want to pursue a clinical career-- and that is a complex process!

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.

The TU Delft Aerospace Engineering Bachelor is one of the most prestigious bachelor programmes the Netherlands has to offer. As it is highly sought-after by students all around the globe, there is a highly competitive selection procedure which needs to be completed to get admitted to this popular degree. A major part of this admission procedure is the selection exam, consisting of three different tests: Mathematics, Physics and First-Year Material.

As a cum laude graduate Aerospace Engineer at TU Delft, who has also been tutoring since 2017, I have a lot of experience and knowledge of the program to help you out with the right preparation to get in. Over the last four years, I have helped tens of students secure a spot! Moreover, I offer a free personalised lesson plan for each student, which is fully based on the admission syllabus and past exams, to ensure an even higher chance of admission for each student.

With my calm and stepwise explanation, weaker topics will be addressed, and your solution procedures will become more effective and accurate. Each lesson will either be theory, exercise-based or an opportunity to talk about the admission, student life, the city of Delft, what to expect from the study and whether it is the right fit for you.

Hi, my name is Federica and I am an astrophysicist. I obtained my PhD from ETH Zürich and, for over ten years, I have been working in international research teams, contributing to space missions such as ESA Euclid and NASA Roman, and collaborating with scientists from all over the world.

For more than ten years, I have also been active in teaching, tutoring and science communication. In my teaching approach, I consider it essential to listen to the student, understand their needs, and identify the way they reason and learn best. This is key to creating a truly personalised learning path that motivates them to engage with the subject and gradually take on more advanced learning challenges.

I helped several students to strengthen the foundations, identify strategic points early, and progressively work towards more advanced problem-solving and exam preparation.

I do not believe in a standard “one-to-many” lesson, but rather in a learning path designed to genuinely consolidate the student’s knowledge, help them become progressively more independent, and make them aware of the practical and interdisciplinary applications that a particular subject can have in their academic journey.

I am fluent in Italian and English, and I am currently strengthening my knowledge of French. Thank you for your attention.
