Observacions i context
Her contemporaries were Lise Meitner (1878-1968), a renowned Austrian scientist who contributed to the discoveries of the element protactinium and nuclear fission; Mileva Marić (1875-1948), a mathematician and the first wife of Albert Einstein, who contributed to the work for which he was awarded the Nobel Prize; and Elsa Neumann (1872-1902), a German physicist. She was the first woman to obtain a doctorate from Humboldt University in Berlin in 1899, a pioneer in aviation research, and an advocate for the inclusion of women in the world of science.
Descripció
This activity aims for students to learn how to represent a chemical reaction through a chemical equation, identifying the reactants and products. Additionally, they should balance the equations and perform stoichiometric calculations. Depending on the students' level, the activity can be carried out using the concept of the mole.
It is interesting to discuss the role of ammonia in the chemical industry and its impact on the economic development of a country.
