What temperature kelvin would .97mol of gas be to occupy 26L at 751.2mmHg?
Answers
Answer: 322.56 Kelvin
Explanation:
Use the Ideal Gas Law

R is the gas constant
T is the temperature in Kelvins
P is the pressure in atmospheres
V is the volume in liters
n is the number of moles of gas

Answers
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

b) (5 Points) Meat begins to feel slimy and it smells when it is spoiled due to
a decomposition reaction with oxygen and carbon dioxide. Why would
meats spoil less rapidly when left unsliced?
Answers
Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.
Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.

New volume v2
Computation:
Using Ideal gas law formula
V1T2 = V2T1
(752)(-10) = (V2)(25)
New volume v2 = 300.8 ml

A soccer player applies a force of 56.6 N to a soccer ball while kicking it. If the ball has a mass of 0.46 kg, what is the acceleration of the soccer ball?
Answers
Answer:
[tex]a=123.04\ m/s^2[/tex]
Explanation:
Given that,
Force applied to a soccer player, F = 56.6 N
The mass of the ball, m = 0.46 kg
We need to find the acceleration of the soccer ball. The force acting on the ball is given by :
F = ma
Where
a is the acceleration
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2[/tex]
So, the required solution is [tex]123.04\ m/s^2[/tex].

Explain why the elements in Group 0 exist as single atoms.
Answers
Group 0 is the noble gas elements in periodic table. They are all unreactive because, they have completely filled electronic configuration and thus they are stable. This stability to be a single element make them so.
What are noble gases?Noble gases are helium, neon, argon, krypton and xenon. They are 18th group elements in periodic table. Also called zero group elements. The general electronic configuration of these elements is ns² np⁶.
Noble gases contains eight electrons in their valence shell and thus completed octet. Atoms with less number of electrons in valence shell tends to attain octet by losing or gaining electrons to their valence shell.
Every elements except noble gases are electron deficient or electron rich. The electron rich elements will lose their electron to attain stability and the elements with less electrons gain them through bonding. That's why they are existing as molecules.
Therefore, the elements of zero group are highly stable and they do not lose or gain electrons to form molecules.
