390 because im cool and awsome
Answer:
Explanation:
Dado que:
masa de oxígeno gaseoso = 100 g
presión = 1 atm
temperatura = 273 K
(a)
número de moles de oxígeno contenidos en el matraz = masa de oxígeno / masa molar de oxígeno
= 100 g / 16 gmol⁻¹
= 6.25 moles
(b) El número de moléculas de oxígeno es el siguiente:
Dado que 1 mol de oxígeno gaseoso contiene 6.023 * 10²³ moléculas de oxígeno.
Entonces, 6.25 moles contendrán:
= (6.25 × 6.023 * 10²³) moléculas de oxígeno.
≅ 3.764 × 10²³ moléculas de oxígeno.
(c) El número de átomos de oxígeno es:
= 2 × 3.764 × 10²³
= 7.528 × 10²³ átomos de oxígeno
(d) Usando la ecuación de gas ideal
PV = nRT
El volumen ocupado por el oxígeno = 
Volumen ocupado por oxígeno = 
Volumen ocupado por oxígeno= 14185.76 m³
Answer:The correct answer is ;
The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
Explanation:
In an oxidation recation addition of oxygen atom takes place or loss of electrons takes place.
In an reduction reaction removal of oxygen atom takes place or gain of electrons takes place.
In the given reaction , the nitrogen atom is present in +2 oxidation state in NO molecule and present in 0 oxidation state in 
molecule. Hence, nitrogen is getting reduced that is reduction reaction. NO is oxidizing agent
In the given reaction , the carbon atom is present in +2 oxidation state in CO molecule and present in +4 oxidation state in 
molecule. Hence ,carbon is getting oxidized that is oxidation reaction. CO is a reducing agent.
Answer:
It was a cold December night shortly after dusk, a likely setting for an event that would prove to be life altering. As fate would have it, this would be the night that I lost the material possession that truly meant the most to me. I would lose the one thing that gave me much pride and joy and excitement. I often think back and liken us to a newlywed couple, for we had only been together for 18 months and were still very much honeymooning. It was a night, a moment, that even now scoffs and mocks me as I travel thither and yonder with her replacement. But she can never be truly replaced and to call my current fix a replacement seems like a sort of blasphemy.
I called her my Blue Angel. That's right! She was a brand new 1999 Atlantic blue Ford Mustang fully equipped with white racing stripes on each side, dark window tint, a rear spoiler, and a post-factory sound system that I installed personally just to complete the "dream ride" effect. We met on April 24, 1999,when my parents introduced us and told me she was all mine as a reward for graduating high school as valedictorian. And what a reward she turned out to be. We went everywhere together. I took her out to eat. When I'd go play ball somewhere, she went with me. Every day from April 24, 1999, to December 22, 2000, we were together. We were bonding in a way a young man can bond with no other, and there truly was no other for me. Other guys had bigger trucks and faster cars, but where my Blue Angel was lacking in size and power, she more than made up for in pure, unadulterated, raw emotion, She never let me down; she was always looking her best and never longing for attention from me or any of the other countless admirers and fans she won over for...
