Explanation:
1) El CO2 que los astronautas exhalan se extrae de la atmósfera de la nave espacial por reacción con KOH según la reacción: CO2 (g) + 2 KOH (l) → K2CO3 (s) + H2O (l) a) Cúantos gramos de CO2 se pueden extraer con 500 g de KOH ? b) Cuántos gramos de agua se producen? 2) Cuando se hacen reaccionar hidrógeno y nitrógeno se produce amoniaco, un fertilizante benéfico para las plantas. ¿Cuántos moles de hidrógeno se requieren para que reaccionen con 12.75 moles de nitrógeno? La reacción es la siguiente: N2 + 3 H2 → 2NH3 3) El propano (C3H8) es usado como combustible en los hogares, reacciona con el oxigeno para producir dióxido de carbono (CO2) y agua (H2O) mediante la siguiente reacción: C3H8 + 5 O2 → 3 CO2 + 4 H2O a) Si se queman 2 Litros de propano (C3H8) calcula los litros de CO2 que se emiten a la atmósfera.
Answer:
a. 4.46 moles de CO₂
b. 80.2 g de H₂O
38.25 moles de H₂
5.55 L de dióxido de carbono
Explanation:
Comenzamos con la reacción: CO₂ (g) + 2 KOH (l) → K₂CO₃ ↓ (s) + H₂O (l)
a. Podemos ver que la relación estequiométrica es 2 a 1.
Pasamos la masa de KOH a moles → 500 g . 1mol/ 56.1g = 8.91 moles
2 moles de KOH necesitan 1 mol de dióxido
Entonces, 8.91 moles necesitarán (8.91 . 1)/2 = 4.46 moles
Convertimos los moles en masa → 4.46 mol . 44g /1mol = 196 g de CO₂
b. Como no tenemos información de los reactivos, trabajamos con el KOH (recorda que siempre hacemos los cálculos con el reactivo limitante).
La relacion estequiometrica también es 2 a 1.
Con 2 moles de KOH producimos 1 mol de agua
Entonces 8.91 moles producirán la mitad, 4.46 moles
Pasamos a gramos → 4.46 mol . 18g /1mol = 80.2 g de H₂O
N₂ + 3H₂ → 2NH₃
En esta relacion, la relación de moles es 1 a 3.
1 mol de N₂ necesita 3 moles de H₂ para llevar a cabo la reacción
12.75 moles de nitrogeno reaccionarán con (12.75 . 3)/ 1 = 38.25 moles de H₂
La siguiente es una reacción de combustión:
C₃H₈ + 5O₂ → 3 CO₂ + 4 H₂O
Como en este caso tenemos volumen, necesitamos averiguar la densidad del propano para sacar la masa y de ahi los moles:
Densidad del propano es 1.83 g/L
Si tenemos 2 Litros de gas, entonces tendremos el doble de masa
2L . 1.83 g/L = 3.66 g
Convertimos a moles → 3.66 g . 1 mol/44g = 0.083 moles
1 mol de propano produce 3 moles de dióxido.
0.083 moles producirán (0.083 .3) /1 = 0.249 moles
Convertimos a gramos → 0.249 moles . 44g/ 1mol = 10.98 g
La densidad del CO₂ es 1.976 g/L
d = m/V → V = m/d → 10.98 g / 1.976 L = 5.55 L

Why is oil so incredibly valuable as an energy source? What is exceptional about its energy density?
Answer:
Easy portability,easy convertability, high calorific value for its unit mass.
Explanation:
Oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.
What is oil?Any chemical compound that is nonpolar, predominantly hydrocarbon-based, hydrophobic, and lipophilic is considered to be an oil. Typically combustible and surface active, oils. Most oils are lipids which become liquid above room temperature and are unsaturated. Classes of chemical substances that may be unconnected in structure, characteristics, and usage are included in the general concept of oil.
They are employed in the production of numerous varieties of paints, plastic bottles, and various other products, as well as for usage as food (such as olive oil), fuel (such as heating oil), lubricant (such as motor oil), and medical uses. Some religious rituals and ceremonies employ specially formulated oils as cleansing elements. Oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.
Therefore, oil is so incredibly valuable as an energy source as it has easy portability, easy convertibility, high calorific value for its unit mass.

Answer:
As you descend in the ocean water temperature and pressure decrease.
Explanation:
"Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. The sinking and transport of cold, salty water at depth combined with the wind-driven flow of warm water at the surface creates a complex pattern of ocean circulation called the 'global conveyor belt.'" - National Ocean Services
