04-10 A power plant burns 100 metric tons of coal per day with a sulfur content of 5%. The coal contains 3% ash (noncombustible

portion). Samples of the ash show that it has a sulfur content of 10% sulfur by weight. Sulfur that is not in the ash is in the flue gases. How many metric tons of SO2 are emitted from the smoke stack each day? Answer: 9.4 ton SO2/d

Answer:

9.4 metric ton of SO₂ are emitted from yhe smoke stack each year.

Explanation:

Total amount = 100 metric ton

Sulphur in the total amount = 5% = 5 metric ton

Ash = 3% = 3 metric ton

Sulphur in the ash = 10% of 3 metric ton = 0.3 metric ton

Sulphur in the flue gases = 5 metric ton - 0.3 metric ton = 4.7 metric ton

Combustion of sulphur: S (s) + O₂ (g) → SO₂ (g)

32 g S _________ 64 g SO₂

4.7 x 10⁶ g ______    x

x = 9.4 x 10⁶ g = 9.4 metric ton of SO₂

Find the mass in grams of 2.65 x 10^24 molecules of cl2
Alina [70]
Moles of Cl2 = 2.65 x 10^24 / 6.02 x 10^23 = 4.4 moles.

Mass of Cl2 in grams = molar mass of Cl2 x moles of Cl2
                                     = 70.906 x 4.4
                                     = 311.98 grams.

Hope this helps!

What is the symbol for moles using the ideal gas equation
vredina [299]

Answer: N is the numbers of moles

Explanation:

An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them may be deduced from kinetic theory and is called the. n = number of moles. R = universal gas constant = 8.3145 J/mol K. N = number of molecules.

Calculate the molar solubility of copper(II) arsenate (Cu3(AsO4)2) in water. Use 7.6 x 10^-36 as the solubility product constant
Molodets [167]
Molar solubility<span> is the number of moles of a substance (the solute) that can be dissolved per liter of solution before the solution becomes saturated. We calculate as follows:

</span>3Cu2+ + 2(AsO4)3-<span> = Cu3(AsO4)2
</span>
7.6 x 10^-36 = (3x^3)(2x^2)
x = 6.62 x 10^-8 M
