¡Hola¡ Soy Amanda Fuentes, estudiante de último año de bachillerato. Siempre me han encantado las ciencias, en especial, la Matemática y la Química. En la materia de Química he ganado concursos de conocimiento a nivel nacional en 1er y 2do año de bachillerato, llegando a formar parte de la Preselección Nacional de mi país; y en muchas ocasiones he impartido clases a mis compañeros. Por estas razones me considero con la capacidad de ayudar a niños y jóvenes a aprender estas materias. Buscaré siempre la forma de ayudarte a conseguir tus metas. La experiencia de aprender no es un castigo, es un placer, solo hay que hacerlo de la forma correcta.

Hi everyone! My name is Rebecca Castellaneta, I'm from Italy and I'm a Biology laureate. I've been a swim instructor for the past five years and a private teacher, too. I'm a tutor of English, Organic and Inorganic chemistry and Biology! The most important thing for me is to understand which are the problems, the doubts, your goals and to help you achieve them, that's why I offer a 20 free minutes meet, to know you and help you! During my lessons I want my students to feel safe in order to ask me questions and tell me if they don't understand something...I'm here for you! :)

I’m Francesca and I’m an organic chemistry student. I’ve a great preparation in scientific subjects such as maths, physics, chemistry, biology and natural sciences. During my classes at university i’ve learn a lot about scientific english reading and comprehending textes and articles. I offer lots of lessons about scientific subje, but I also propose english lesson for level B1-B2 to mid and high school students. I can also help to comprehend and translate english articles for university student ☺️
Sono Valentina 🤗,, ⚗️Perito chimico👩🏻🔬, laureata in 💊💉infermieristica👩🏻⚕️ con grande passione per lo studio 🎖️📚📖e l'insegnamento👩🏻🏫. Da anni faccio ripetizioni a ragazzi di tutte le età 👩👧👦👨👨👧👧in ambiti 💊🔬scientifici 🔬⚗️collezionando grandissimi soddisfazioni 🥂🍾e risultati🎊. Il mio metodo è prontato sul 🧠 ragionamento⚙️ anziché allo studio memorico💆, favorendo un approccio più pragmatico🎲♟️ e rapportato alla quotidianità. Durante le spiegazioni utilizzo esercizi📖 che commento e descrivo in modo che tutti i passaggi vengano compresi 💡 e garantendo la tua autonomia. ❗❗Non aspettare ancora ▶️ iniziamo subito ▶️▶️ LET'S GO ❗❗🥊🥋

Holaa me llamo Nerea y tengo 20 años, actualmente estudio 3° de Química🧪 en la Universidade de Santiago de Compostela, soy muy paciente, y podria explicar las cosas de manera que los alumnos las entiendan, ya que yo también necesité en su momento ayuda y al final logré tener una media de 9 en las asignaturas de quimica y física en el instituto, el horario⏰️🗓 se hablaria para llegar a un consenso ya que tengo algunas prácticas y clases en academias, pero no dudaria en estar disponible los findes también💫, todo lo que se necesite!!🙏

Pericyclic Reactions
(Peri mean around and cyclic mean circle) So, Pericyclic mean around the circle.
It may be define as:
“A pericyclic reaction is a concerted reaction that proceeds through a cyclic transition state.”
Characteristics of pericyclic all reactions:
1) All pericyclic reactions are single step mechanism.
2) All pericyclic reactions have conjugated cyclic transition state.
3) All pericyclic reactions are internally self-sufficient mean (no extra reagent and catalyst is required) they initiated by thermally or photo chemically.
4) All pericyclic reactions are stereospecific in nature mean (specific stereoisomer in reactants form specific stereoisomer in products).
5) All pericyclic reactions show equilibrium state mean (reactants and products have ability to inter change with each other).
Types of pericyclic reactions:
There are following types of pericyclic reactions
1) Electrocyclic reactions
2) Cycloaddition reactions
3) Sigmatropic rearrangement
1) Electrocyclic Reactions
“An electrocyclic reaction is a reversible reaction that can involve ring closure or ring opening of one molecule of reactant to form one molecule of product.”
Type of Electrocyclic Reactions:
i) Electrocyclic ring closure reactions:
“An electrocyclic ring closure is an intramolecular reaction that forms a cyclic product containing one more σ bond and one fewer π bond than the reactants.”
ii) Electrocyclic ring opening reactions:
“An electrocyclic ring opening is a reaction in which an σ bond of a cyclic reactant is cleaved to form a conjugated product with one more π bond.”
To draw the product in each reaction, use curved arrows and begin at a π bond. Move the π electrons to an adjacent carbon-carbon bond and continue in a cyclic fashion.
As a seasoned mathematics educator, I bring a wealth of knowledge and expertise to the table. With a proven track record of helping students not only understand but also excel in mathematics, I am committed to your success. My teaching style is interactive, tailored to your needs, and designed to boost your confidence in tackling mathematical challenges.
I believe in making math fun and relatable, using real-life examples to connect theory to practical applications. Whether you're struggling with basic arithmetic or tackling advanced calculus, I'm here to provide clear explanations and patient guidance.
My goal is to foster a deep understanding of mathematical concepts, encouraging critical thinking and problem-solving skills. With me as your tutor, you'll not only improve your grades but also gain a lasting appreciation for the beauty of mathematics. Join me on this educational journey, and let's conquer math together!

Ciao , mi chiamo Simona Belardi e sono una laureanda in Chimica e Tecnologia Farmaceutica .
Da tanti anni seguo i ragazzi che hanno difficoltà con le materie scientifiche, sono a disposizione per aiutare studenti di tutte le età , dalle media ,al liceo ,all'università per materie quali chimica ,biologia e anche matematica !
So perfettamente che per tanti ragazzi capire le materie scientifiche è complicato e certe volte è necessario avere qualcuno accanto che riesca a trovare il modo giusto per spiegare l'argomento.
Con tutti gli alunni che seguo riesco a instaurare un ottimo rapporto, cerco sempre di trovare il metodo più adatto alle esigenze dello studente ,perché credo che non tutti abbiano lo stesso modo di apprendere .
Ho avuto anche esperienza con una studentessa con diagnosi di discalculia ,insieme siamo riuscite a superare tante difficoltà!
Insieme riusciremo a superare tutti gli ostacoli!
