Answer:
1.18x10⁸L of SO₂ and 2.36x10⁸L of H₂S
Explanation:
The balanced reaction is:
8SO₂(g) + 16H₂S(g) → 16H₂O(l) + 3S₈(s)
To solve this question we must find the moles of S₈ in 4.50x10⁵kg. With these moles and the reaction we can find the moles of SO₂ needed to react (Twice these moles = Moles Of H₂S needed). Using PV = nRT we can find the volume of the gas required:
Moles S₈ - molar mass: 256.52g/mol-
4.50x10⁵kg = 4.50x10⁸g * (1mol / 256.52g) =
1.75x10⁶ moles S₈
Moles SO₂:
1.75x10⁶ moles S₈ * (8mol SO₂ / 3mol S₈) = 4.68x10⁶ moles SO₂
Moles H₂S:
4.68x10⁶ moles SO₂ * 2 = 9.36x10⁶ moles H₂S
The volume could be obtained as follows:
PV = nRT
V = nRT / P
V is volume in liters
n are moles: 4.68x10⁶ moles SO₂ and 9.36x10⁶ moles H₂S
R is gas constant = 0.082atmL/molK
T is absolute temperature = 22°C + 273.15 = 295.15K
P is pressure = 0.961atm
Replacing:
Volume SO₂ and H₂S:
4.68x10⁶ moles * 0.082atmL/molK * 295.15K / 0.961atm =
1.18x10⁸L of SO₂ and:9.36x10⁶ moles H₂S * 0.082atmL/molK * 295.15K / 0.961atm =
2.36x10⁸L of H₂SHow many grams of sulfur trioxide are required to produce 2.00 mol of sulfuric acid in an

लेख्नुहोस् । (Deserts are very hot during the day and very cold
during the night. Give reason.)
Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert. And at night, the sun no longer heats the desert and the heat from the day doesn't stay trapped. Because of this, some deserts can get extremely cold at night, dropping to temperatures below 40F.
Hope this helps!! Have a wonderful day!!
It is actually sand, which turns the entire phenomenon hot. Sand cannot hold the heat. It acts like a mirror to the sun. During the daytime, it stays warm, and when the Sun is absent it loses all its heat making the nights colder. There’s nothing in the desert that can either absorb heat from the sun or hold it on the surface when the sun is set.

Why is nuclear fusion not used to produce electricity?
O A. Fusion requires conditions that exist only in the cores of stars.
B. Fusion produces nuclear waste.
C. Fusion requires steam turbines, which are expensive.
D. Fusion produces only a small amount of energy.
Answer: A is correct for ape.x
Explanation:
Nuclear fusion not used to produce electricity because fusion requires conditions that exist only in the cores of stars. Hence option A is correct.
What is nuclear fusion?Nuclear fusion is defined as the process that produces a single heavier atomic nucleus from the union of two lighter ones while releasing enormous quantities of energy. Controlled atom fusion generates around four million times as much energy as controlled nuclear fission and chemical processes like burning coal, oil, or gas.
Normal electrostatic interactions between positively charged nuclei prohibit them from coming close enough to collide and allow fusion to happen, hence fusion is not feasible. Fusion might be used to generate electricity economically if there was a sufficiently big and sustained energy "profit".
Thus, nuclear fusion not used to produce electricity because fusion requires conditions that exist only in the cores of stars. Hence option A is correct.

how many moles of
nitrogen gas?
Answer:
15moles
Explanation:
The balanced equation of this reaction is as follows:
N2 + 3H2 → 2NH3
Molar mass of H2 = 2g/mol
mole = mass/molar mass
mole = 90/2
mole = 45moles.
Based on the above balanced equation, 1 mole of nitrogen gas (N2) reacts with 3 moles of hydrogen gas (H2)
Hence, 45moles of hydrogen gas will produce (45 × ⅓) = 15moles of nitrogen gas (N2).

Explanation:
Una solución hallar punto de vista física y punto de vista químico (sal) 50g de sal y 250 ml de agua hallar %m/m %m/v molalidad, molaridad, fracción molar del soluto y del solvente
Answer:
% m/m = 16.6%
% m/v = 20%
3.42 m (molalidad)
3.42 M (molaridad)
Fraccion molar del soluto = 0.06
Fraccion molar del solvente = 0.94
Explanation:
Nuestra solución está compuesta por:
Soluto: 50 g de sal
Solvente: 250 mL de agua.
%m/m %m/v molalidad, molaridad, fracción molar del soluto y del solvente son distintas formas de definir la concentración:
% m/m son los gramos de soluto cada 100 g de solución.
No sabemos la masa de solución pero con la densidad del agua (solvente), sabemos que los 250 mL contienen 250 gramos de solvente. (Densidad del agua 1g/mL). En conclusión, la masa de solución es 50 g + 250g = 300
% m/m = (50g /300g ) . 100 = 16.6%
Vamos a definir que el volumen de la solución es igual al del solvente: 250 mL.
% m/v = la masa de soluto, cada 100 mL de solución
= (50 /250) . 100 = 20 %
Molalidad, son los moles de soluto por cada kg de solvente.
Convertimos gramos a kg → 250 g . 1kg /1000g = 0.25kg
Convertimos la masa de soluto (sal) a moles.
NaCl → 50 g . 1mol/ 58.45g = 0.855 moles
m = 0.855 /0.25 → 3.42 m (molalidad)
Molaridad son los moles de soluto por cada L de solución.
Convertimos mL a L → 250 mL . 1kg / 1000mL = 0.25 L
sabiendo que los moles de soluto son 0.855, en este caso la molaridad es igual a la molalidad ( 3.42 M)
Para calcular la fracción molar, necesitamos moles de soluto y de solvente.
Ya contamos con los moles de soluto.
Moles de solvente: 250 g . 1mol /18g = 13.89 mol
Moles totales = 0.855 + 13.89 = 14.745
Fracion molar del soluto: (0.855/ 14.745) = 0.06
Fraccion molar del solvente: (13.89 / 14.745) = 0.94

the gas?
I
Answer:
8.75 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{3.5 \times 6}{2.4} = \frac{21}{2.4} \\ = 8.75[/tex]
