A West Virginia coal is burned at a rate of 8.02 kg/s. The coal has a sulfur content of 4.40 % and the bottom ash contains 2.80

aleksley [76]

Answer: The annual emission rate of SO2 is 1.08 × $10^{7}$ kg/yr

Explanation:

The rate r at which the coal is been burnt is 8.02 kg/s.

Amount of sulphur in the burning coal is given as 4.40 %

i.e., 4.4/100 × 8.02 = 0.353 kg/s. Which is equivalent to the rate at which the sulphur is been burnt.

Since the burning of sulphur oxidizes it to produce SO2, it follows that the non-oxidized portion of the sulphur will go with the bottom ash.

The bottom ash is said to contain 2.80 % of the input sulphur.

Hence the portion of the SO2 produced is 100 — 2.80 = 97.20 %.

The rate of the SO2 produced is percentage of SO2 × rate at high sulphur is been burnt.

= 97.20/100 × 0.353 kg/s.

= 0.343 kg/s.

To get the annual emission rate of SO2, we convert the kg/s into kg/yr.

1 kg/s = 1 kg/s × (60 × 60 × 24 × 365) s/yr

1 kg/s = 31536000 kg/yr

Therefore, 0.343 kg/s = 0.343 × 31536000 kg/yr

= 10816848 kg/yr

= 1.08 × 10^7 kg/yryr.

What is the difference between breccia rock and conglomerate rock

Klio2033 [76]

Breccia rocks and conglomerate rocks are said to be very similar rocks. They both are sedimentary rocks. Their difference lies on their shapes. For breccia rocks, large particles are angular in shape which is different from the conglomerate rocks where they are rounded.

A chemical reaction occurring in a cylinder equipped with a moveable piston produces 0.601 mol of a gaseous product. If the cyli

netineya [11]

Answer:

4.33 L

Explanation:

Assuming ideal behaviour and that all 0.300 moles of gas reacted, we can solve this problem using Avogadro's law, which states that at constant temperature and pressure:

V₁n₂ = V₂n₁

Where in this case:

V₁ = 2.16 L

n₂ = 0.601 mol

V₂ = ?

n₁ = 0.300 mol

We input the given data:

2.16 L * 0.601 mol = V₂ * 0.300 mol

And solve for V₂:

V₂ = 4.33 L
