Answer:

Scientists believe that Earth and the other planets formed _____.

during the same time span and from the same material as the sun

Explanation:

Scientists believe that the planets including earth formed at the same time span as the sun, as well as from the same materials. Because their theory says that after a dramatic gravitational collapse from a space dust occurred the sun and planets were created. However, they were not the same as they are today. But they have the same elements and the same materials. And everything formed from these materials. we could even say we are made of stardust because the elements that made us were created at that time according to their thesis.

12.36Un balón lleno contiene 12 kg de oxígeno, O2, bajo una presión ma-nométrica de 40 atm. Determine la masa de oxígeno que se

const2013 [10]

Answer:

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Explanation:

Asúmase que el balón es rígido. Supongamos que el oxígeno se comporta como un gas ideal, entonces la ecuación de estado es la siguiente:

$P\cdot V = \frac{m\cdot R_{u}\cdot T}{M}$ (1)

Donde:

$P$ - Presión, medida en atmósferas.

$V$ - Volumen, medido en litros.

$m$ - Masa, medida en kilogramos.

$M$ - Masa molar, medida en kilogramos por kilomol.

$T$ - Temperatura, medida en Kelvin.

$R_{u}$ - Constante de los gases ideales, medida en atmósfera-litros por kilomol-Kelvin.

El aire experimenta un proceso isocórico e isotérmico, entonces obtenemos la siguiente relación:

$\frac{P_{1}}{m_{1}} = \frac{P_{2}}{m_{2}}$ (2)

Nótese que los subíndices 1 y 2 representan los estados inicial y final de proceso.

Si sabemos que $P_{1} = 41\,atm$ , $m_{1} = 12\,kg$ y $P_{2} = 25\,atm$ , entonces la masa final del aire es:

$m_{2} = \frac{P_{2}}{P_{1}} \cdot m_{1}$

$m_{2} = \left(\frac{25\,atm}{41\,atm}\right)\cdot (12\,kg)$

$m_{2} = 7.317\,kg$

La masa que se ha extraído del balón es:

$\Delta m = m_{1}-m_{2}$

$\Delta m = 12\,kg-7.317\,kg$

$\Delta m = 4.683\,kg$

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Samuel has a block of modeling clay, three heavy blocks, and a hot plate covered by a tray as shown. How could he use these item

Olegator [25]

Answer:

Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray.

Explanation:

Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray is used for forming a metamorphic rock. Metamorphic rocks are formed when the rocks are placed to high heat, high pressure, hot mineral-rich fluids or combination of all these three factors. Conditions like these are found deep within the Earth so by placing block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray formed metamorphic rock.
