Answer:

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:

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):

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

Answer:The correct answer is option C.
Explanation:

At STP, 1 mol of gas occupies 22.4 L of volume
So, 100.0 L volume of
will be occupied by :

According to reaction 2 moles
are obtained from 1 mole of
.
Then,4.4642 moles of
will be obtained from :
that is 2.2321 moles of 
Mass of
gas:
Moles of
gas Molar mass of
gas:

Hence, the correct answer is option C.

Answer:
Crack the windows
Explanation:
believe it or not, one researcher actually tested this back in the 1980s: A study in Pediatrics found that cracking the window 5 centimeters lowered the temperature in a car by about 28°F on a 98°F day .
