LEY DE LAS PROPORCIONES DEFINIDAS O LEY DE PROUST

La ley de las proporciones definidas, formulada por el químico francés Joseph Proust en 1794, establece que un compuesto siempre está formado por los mismos elementos en la misma proporción de masa, sin importar su origen o el método de preparación.

LEY DE LAS PROPORCIONES DEFINIDAS O LEY DE PROUST

Type in the name of the multiple-perspectives text.

Example: Bridge to Terabithia by Katherine Paterson

definidas establecida por el francés Joseph Proust en 1794

una consecuencia natural de la idea de que los elementos están formados por átomos idénticos e indestructibles. Proust realizó gran parte de su investigación en España y es allí donde logra determinar que la mezcla de elementos puede llevarse a cabo en una relación de peso continuo indistintamente del proceso inmediato que lo formó.



Identify an important issue from the text that is being presented from different angles. Type it in.

Decide on the fourth point of view

Type in the name of the last character whose perspective on the issue you are going to present.

Cuando varias sustancias se unen para formar un compuesto, lo hacen siempre en una relación constante de masa.

Point of view

Type in a relevant quote that highlights the character's point of view. Try to follow a citation format: author's name, chapter, and page.

Example: I can't get the poetry of the trees,' he said. She nodded. Don't worry,' she said. You will someday. He believed her.' (Paterson, 4. 24)

How is the viewpoint introduced in the story?

Choose an answer:

First person point of view - using the personal pronouns 'I' or 'we'Second person point of view - using the personal pronoun 'you'Third person point of view - using the third-person pronouns 'he', 'she' and 'they'Omniscient point of view - an all-seeing observer tells the story

2H2 + O2 → 2H2O No importa la cantidad de agua, puede ser del tamaño de una piscina o tan solo una gota, la proporción de combinación siempre será 2:1.

Whose character does the third point of view belong to?

Type in his/her name.

Example: Mr. Aarons, Jesse's father.

entre la masa de sustancias reactivas y los productos en una reacción química.

What does the character think, say or do that suggests their perspective on the issue?

Type in a quote and try to maintain the citation format.

Example: 'He would like to show his drawings to his dad, but he didn't dare. (...) He'd thought his dad would be pleased. He wasn't. What are they teaching in that damn school? he had asked.' (Paterson, 2.8)

Es por esto por lo que también se le conocía como ley de proporciones definidas. Para la industria y el ambiente de laboratorio, estas leyes son muy útiles en el cálculo de la cantidad de reactivos necesarios para la preparación de sustancias, así como el número de productos que debe ser producido.
