<span>Steel is a solid at standard temperature and pressure conditions. For a solid, the particles are found to be oscillating about a fixed point. However, steel is a metal so this holds true for the positively charged nuclei of the particles. Just like any other metal, the electrons are free to move about, allowing steel to exhibit its properties such as heat conduction and electricity conduction. The reason the positive particles are fixed in place is because the intermolecular forces are very strong in solids, the strongest out solids, liquids and gases.</span>
Answer:
Explanation:
ΔTemp => 35⁰C(108K) increases to 57.9⁰C(330.9L) => increases volume (Charles Law)
Use the Kelvin Temperature values in a ratio that will increase the original volume.
ΔVol = 6.33L(330.9/108.0) => gives a larger volume. Using 108.0/330.9 would give a smaller volume and would be contrary to what the problem is asking.
ΔPress => 342 mmHg increases to 821 mmHg => decreases volume (Boyles Law)
Use the pressure values in a ratio that will decrease the original volume.
ΔPress = 6.33L(342/821) => gives a smaller volume. Using 821/342 would give a larger volume and would be contrary to what the problem is asking.
Now, putting both ΔTemp together with ΔPress => net change in volume. (Combined Gas Law)
ΔVol = 6.33L(330.9/108.0)(342/821) = 8.08L (final volume of gas).
___________________
This problem can also be worked using the combined gas law equation:
P₁V₁/T₁ = P₂V₂/T₂ => V₂ = P₁V₁T₂/T₁P₂
V₂ = [(342mm)(6.33L)(330.9K)]/[(108K)(821mm)] = 8.08L (final volume of gas)
<span> Son organismos que pertenecen al Nivel de Organización Protoplasmático. Son UNICELULARES y se distinguen por no poseer un Núcleo bien organizado. Son PROCARIOTAS porque el material genético (ADN o Cromosomas) al no tener Carioteca o Membrana Nuclear, se encuentran dispersos en el Citoplasma. Comprenden a las Cianofíceas y Bacterias. Las Cianofíceas o Algas verde azuladas son Autótrofos, ya que realizan la Fotosíntesis y algunas Bacterias se nutren por Absorción, ya sea descomponiendo a sustratos orgánicos como las Saprófitas, o infectando a un organismo vivo y viviendo a expensas de él como las Parásitas y otras son Heterótrofas y Autótrofas. Poseen un Sistema de Nutrición AUTÓTROFA, HETERÓTROFA y por ABSORCIÓN. Las Bacterias son Células muy pequeñas, que tienen Reproducción Asexual por Fisión Binaria. Tienen Pared Celular porosa. Presentan diferentes Formas (Cocos, Bacilos, Espirilos, Vibriones). Producen Enfermedades (Tuberculosis, Lepra, Sífilis, Neumonia, etc.) Hay Bacterias Beneficiosas (Producción de alcohol y vinagre, quesos, yogurth, etc.). Las CIANOBACTERIAS poseen CLOROFILA y un Pigmento azul llamado FICOCIANINA. Pueden estar libres o en colonias. </span>
Here are two examples of strong nuclear force !
Protons and nucleons
I hope that's help !
Answer:
a correct Lewis diagram for CO2 would look something like this
Explanation:
One C and 2 O. Both O have 4 extra dots and 2 lines/bonds to the C. C has no extra dots.
Hope this helps!
