Un recipiente cerrado, de 4,25 L, con tapa móvil, contiene H2S(g) a 740 Torr y 50,0°C. Se introduce en ese recipiente N2(g) a te
yulyashka [42]

Answer:

n_{N_2}=6.41mol

Explanation:

¡Hola!

En este caso, teniendo en cuenta la información dada por el problema, inferimos que primero se debe usar la ecuación del gas ideal con el fin de calcular las moles de gas que se encuentran al inicio del experimento:

PV=nRT\\\\n=\frac{RT}{PV} \\\\n=\frac{0.08206\frac{atm*L}{mol*K}*(50.0+273.15)K}{740/760atm*4.25L}\\\\n=6.41mol

Seguidamente, usamos la ley de Avogadro para calcular las moles finales, teniendo el cuenta que el volumen final es el doble del inicial (8.50 L):

n_2=\frac{6.41mol*8.50L}{4.25L}\\\\n_2=12.82mol

Quiere decir que las moles de N2(g) que se agregaron son:

n_{N_2}=12.81mol-6.41mol\\\\n_{N_2}=6.41mol

¡Saludos!

Caitlin told Teddy that she heard that the largest diamond was found yesterday in Africa. What would be the best source of resea
matrenka [14]
B, the Internet.

If Caitlin told Teddy that the largest diamond was found YESTERDAY then it wouldn't be in last month's science magazine. It also wouldn't be able to be in an encyclopedia at the library because there wouldn't have been any time to write, publish, and for the library to get the encyclopedia in one day. Caitlin's parents may not know about Caitlin's claim or about the diamond in the first place. The Internet would likely have an article about the news-breaking diamond as soon as possible.
