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?9.4 ton so2/d

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

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
