Stolb23 [73]3 years ago

Answer:

En química y física, la teoría atómica es una teoría científica sobre la naturaleza de la materia que sostiene que está compuesta de unidades discretas llamadas átomos. Empezó como concepto filosófico en la Antigua Grecia y logró ampliar aceptación científica a principios del siglo XIX cuando los descubrimientos en el campo de la química demostraron que la materia realmente se comportaba como si estuviese hecha de átomos.

La palabra átomo proviene del adjetivo en griego antiguo átomos, que significa «indivisible». Los químicos del siglo XIX empezaron a utilizar el término en relación con el número creciente de elementos químicos irreducibles.1​ Cerca del cambio al siguiente siglo, a través de varios experimentos con electromagnetismo y radiactividad, los físicos descubrieron que los "átomos indivisibles" eran de hecho un conglomerado de varias partículas subatómicas (principalmente, electrones, protones y neutrones), las que pueden existir separadas unas de otras. De hecho, en ciertos entornos extremos, como las estrellas de neutrones, la presión y la temperatura extremas impiden que los átomos puedan existir en absoluto.

Ya que se descubrió que los átomos podían dividirse, los físicos inventaron el término «partículas elementales» para describir las partes "indivisibles", aunque no indestructibles, de un átomo. El campo de ciencia que estudia las partículas subatómicas es la física de partículas y es en este campo donde los físicos esperan descubrir la auténtica naturaleza fundamental de la materia

What term expresses the ratio of moles of reactants and products according to the coefficients in the balanced chemical equation
bogdanovich [222]

Answer:

A) mole ratio

Explanation:            

<em>A mole ratio</em>, also known as a mole-to-mole ratio, <em>is ​the ratio between the amounts in moles of one reactant/product to the moles of the other reactant/product. </em>This ratio is determined considering the coefficients in a balanced chemical equation. This ratio is used in chemical problems as a conversion factor between the compounds involved in the reaction.

I hope you find this information useful and interesting! Good luck!

In a mixture of hydrogen and nitrogen gases, the mole fraction of nitrogen is 0.333. If the partial pressure of hydrogen in the
notka56 [123]

Answer:

P_T=112.4torr

Explanation:

Hello there!

In this case, since these problems about gas mixtures are based off Dalton's law in terms of mole fraction, partial pressure and total pressure, we can write the following for hydrogen, we are given its partial pressure:

P_{H_2}=x_{H_2}*P_T

And can be solved for the total pressure as follows:

P_T=\frac{P_{H_2}}{x_{H_2}}

However, we first calculate the mole fraction of hydrogen by subtracting that of nitrogen to 1 due to:

x_{H_2}+x_{N_2}=1\\\\x_{H_2}=1-0.333=0.667

Then, we can plug in to obtain the total pressure:

P_T=\frac{75.0torr}{0.667}\\\\P_T=112.4torr

Regards!
