I am a first year student of Biomedical Sciences in Edinburgh. I was born in Spain but my parents are from Poland, so I speak both languages. Last year I finished studying the International Baccalaureate and the Spanish Baccalaureate at the same time. One of my main subjects was chemistry.
I am a responsible, organized person and I really like teaching languages and chemistry so my classes will be fun, interesting and totally worth it. I can teach grammar, pronunciation, etc. I have experience of teaching higher level of spanish. I also love chemistry and I am good at it because I did two Baccalaureates and that gave me the advantage of being able of studying it in depth

The rate of a reaction is affected by the concentration of the reactants, the action of a catalyst and the temperature.
If we change the concentration of the reactantants, the reaction rate is going to change, because the rate is the mathematical expression of the change in concentration of a compound over time.
The addition of a catalyst lowers the activation energy so less energy is required and the process can occur faster.
The last parameter that affects the rate of a reaction is the temperature. This is because if it rises, the particles move faster and there are more collisions between them.see more
Definite articles are used when we talk about something specific. There are four definite articles: La (femenine, singular), Las (femenine, plural), El (masculine, singular), Los (masculine, plural). For example: el coche de mi padre es rojo (My dad's car is red) . As we are referring to a specific car we use the definite article in singular and masculine because car is masculine.
Indfinite articles are used when we talk about something that is not specific. There are four indefinite articles: una (femenine, singular), unas (femenine, plural), un (masculine, singular), unos (masculine, plural). For example: Ayer fui a un restaurante (yesterday I went to a restaurant). We use the indefinite article because we do not talk about a specific restaurant and we use un because restaurant is masculine and singular.see more
