There is only one calcium atom because the subscript 3 applies only to the oxygen. Outside of the parentheses, the subscript 2 only applies to the chlorate ion. Therefore, there is only one calcium atom because there are no coefficients and subscripts. (Also drawing it out will help)

Most of the sulfur used in the United States is chemically synthesized from hydrogen sulfide gas recovered from natural gas well

Rom4ik [11]

Answer:

The rate at which sulfur dioxide is being produced is 0.90 kg/s.

Explanation:

Volume of oxygen gas consumed in second ,V= 994 L

Pressure of the gas = p

Temperature of the gas = T = 170°C= 170 + 273 K=443 K

Moles of oxygen gas consumed in a second = n

$PV=nRT$ ( ideapl gas equation)

$n=\frac{PV}{RT}=\frac{0.77 atm\times 994 L}{0.0821 atm L/mol K\times 443 K}$

n = 21.044 mole

Moles of dioxygen gas consumed per second = 21.044 mol

$2H_2S(g)+3O_2(g)\rightarrow 2SO_2(g)+2H_2O(g)$ (Claus process)

According to reaction, 3 moles of dioxygen gives 2 moles of sulfur dioxide gas.Then 21.044 moles of dioxygen will give;

$\frac{2}{3}\times 21.044 ol=14.029 mol$ of sulfur dioxide

Mass of 14.029 moles of sulfur dioxide gas;

14.029 mol × 64 g/mol = 897.86 g

897.86 g = 0.89786 kg ≈ 0.90 kg

Mass of sulfur dioxide produced per second = 0.90 kg

The rate at which sulfur dioxide is being produced is 0.90 kg/s.

Carbon cycle is returned to the atmosphere primarily by the respiration of consumer.

natima [27]

Carbon is produced by producers, consumed by consumers, released by consumers, and returned to the air and soil by decomposers.
