17. A sample of oxygen gas has volume 150.0 mL, at 0.947 atm, what will be the volume of the gas at 750.12 mm of Hg if temperature remain constant.

Answers

Answer:

143.9 mL is the new volume for the gas.

Explanation:

Let's apply one of the gases law to solve this problem:

Boyle's law states that the product of pressure and volume remains constant when the T° is not modified.

P₁ . V₁ = P₂ . V₂

Be careful because we have T° in mmHg. We need to convert to atm:

750.12 mmHg . 1 atm / 760 mmHg = 0.987 atm

We replace data:

150 mL . 0.947 atm = 0.987 atm . V₂

V₂ = (150 mL . 0.947 atm) / 0.987 atm

V₂ = 143.9 mL

This term P . V comes from the Ideal Gases Law

P . V = n . R . T

In a chemical reaction, the number of moles of the reactants
A.
should always be equal to the number of moles of the products.
B.
depends on the amount of product that is formed.
C.
should never be equal to the number of moles of the products.
D.
may or may not be equal to the number of moles of the products.

Answers

Answer:

may or may not be equal to the number of moles of the products.

Explanation:

A chemical reaction involves the interaction between reactants to yield products. The number of moles of reactants and products in the system depends on the stoichiometry of the reaction.

The balanced reaction equation shows us the number of moles of reactants and products involved in the reaction.

Hence, in the balanced chemical reaction equation; the number of moles of reactants may or may not be equal to the number of moles of the products.

If a sample of oxygen has a volume of 160 L at 91 degrees celsius what will the oxygen be when the temperature drops to 0.00 degrees celsius.

Answers

Answer:

120 L

Explanation:

Step 1: Given data

Initial volume (V₁): 160 LInitial temperature (T₁): 91 °CFinal volume (V₂): ?Final temperature (T₂): 0.00 °C

Step 2: Convert the temperatures to the Kelvin scale

We will use the following expression.

K = °C + 273.15

K = 91°C + 273.15 = 364 K

K = 0.00°C + 273.15 = 273.15 K

Step 3: Calculate the final volume occupied by the oxygen

Assuming ideal behavior and constant pressure, we can calculate the final volume occupied by the oxygen using Charles' law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 160 L × 273.15 K/364 K = 120 L

2 NABr + Ca(OH)2 = CaBr2 + 2 NaOH How many moles of CaB 2 are produced, if 14.72 moles of NaBr and excess Ca(OH) 2 react?

Answers

Answer: 7.36 moles of [tex]CaBr_2[/tex] will be produced.

Explanation:

We are given:

Moles of NaBr = 14.72 moles

The given chemical equation follows:

[tex]2NaBr+Ca(OH)_2\rightarrow CaBr_2+2NaOH[/tex]

By the stoichiometry of the reaction:

2 moles of NaBr produces 1 mole of calcium bromide

So, 14.72 moles of NaBr will produce = [tex]\frac{1}{2}\times 14.72=7.36mol[/tex] of calcium bromide

Hence, 7.36 moles of [tex]CaBr_2[/tex] will be produced.

PLEASE ANSWER QUICKLY!! 25. Which gas sample contains a total of 3.0 x 1023 molecules?
A) 71 g of Cl2
B) 2.0 g of H2
C) 14 g of N2
D) 38 g of F2

Answers

Answer:

14 g of N2

Explanation:

If we look at the options, we will notice that the correct answer needs to be a gas that has about half of the molecular mass of the gas.

If we consider nitrogen gas whose molecular mass is 28g/mol, half of the molecular mass is 14 g.

So;

28g of N2 contains 6.02 × 10^23 molecules of N2

14g of N2 contains 14 × 6.02 × 10^23 /28

= 3.0 x 10^23

De la siguiente reacción química Fe2O3 + 3 H2O → __Fe(OH)3 para que se cumpla el balanceo en ella, en el espacio qué coeficiente estequiométrico se debe asignar

Answers

Answer:

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

Explanation:

La ley de conservación de la materia establece que, dado que no se puede crear ni destruir ningún átomo en una reacción química, el número de átomos que están presentes en los reactivos debe ser igual al número de átomos presentes en los productos.

Luego, debes equilibrar la ecuación química. Para eso, primero debe mirar los subíndices al lado de cada átomo para encontrar el número de átomos en la ecuación. Si el mismo átomo aparece en más de una molécula, debes sumar sus cantidades.

Los coeficientes ubicados frente a cada molécula indican la cantidad de cada molécula para la reacción. Este coeficiente puede modificarse para equilibrar la ecuación, del mismo modo que nunca debe alterar los subíndices.

Al multiplicar el coeficiente mencionado por el subíndice, obtienes la cantidad de cada elemento presente en la reacción.

En este caso la reacción química es:

Fe₂O₃ + 3 H₂O ⇒ ____ Fe(OH)₃

Entonces, teniendo en cuenta todo lo anterior, se puede determinar la cantidad de elementos en cada lado de la ecuación:

Lado izquierdo: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H Lado derecho: 1 hierro Fe, 3 oxígeno O y 3 hidrógenos H

Se puede observar que la reacción química no esta balanceada porque se tiene diferentes cantidades de cada elemento a cada lado de la reacción. Para equilibrarla, se comienza balanceando el hierro. Para eso, el coeficiente estequiométrico debe ser dos:

Fe₂O₃ + 3 H₂O ⇒ 2 Fe(OH)₃

Entonces:

Lado izquierdo: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H Lado derecho: 2 hierro Fe, 6 oxígeno O y 6 hidrógenos H

Ahora, a cada lado de la reacción se tiene la misma cantidad de cada elemento, por lo que la reacción esta balanceada.

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Jupiter and Saturn are substantially larger than Uranus and Neptune, and each pair of planets has a somewhat different composition.Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it, particularly using NASA's Kepler Space Telescope. These exoplanets (as they are called) are being examined to learnmore about how our solar system came to be.

2. [tex]V_2=8000mL[/tex]

3. [tex]V_2=176.3L[/tex]

Explanation:

¡Hola!

En este caso, dada la información para estos problemas, procedemos de la siguiente manera, basado en las leyes de los gases ideales:

1. Una masa de aire ocupa un volumen de 5 litros a una temperatura de 120 °C Cual será el nuevo volumen si la temperatura se reduce a la mitad:

Aqui, utilizamos la ley de Charles, asegurándonos que la temperatura está en Kelvin:

[tex]\frac{T_2}{V_2} =\frac{T_1}{V_1} \\\\V_2 =\frac{V_1T_2}{T_1} \\\\V_2 =\frac{5L*196.5K}{393K} \\\\V_2=2.5L[/tex]

2. Un gas ideal ocupa un volumen de 4000 ml a una presión absoluta de 1500 kilo pascal Cual será la presión si el gas es comprimido lentamente hasta 750 kilo pascal a temperatura constante?

Aquí, utilizamos la ley de Boyle, dado que la temperatura se mantiene constante, calculando el volumen, ya que lo que se da es la presión final:

[tex]\neq P_2V_2=P_1V_1\\\\V_2=\frac{P_1V_1}{P_2}\\\\ V_2=\frac{4000mL*1500kPa}{750kPa}\\\\V_2=8000mL[/tex]

3. Un gas ocupa un volumen de 200 litros a 95°C y 782 mmHg Cual será el volumen ocupado por dicho gas a 65°C y 815 mmHg:

Aquí, utilizamos la ley combinada de los gases ideales, asegurándonos que las temperaturas están en Kelvin:

[tex]\frac{T_2}{P_2V_2} =\frac{T_1}{P_1V_1} \\\\V_2 =\frac{P_1V_1T_2}{P_2T_1} \\\\V_2 =\frac{782mmHg*200L*338K}{815mmHg*368K}\\\\V_2=176.3L[/tex]
