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
Answer:
The answer is a mixture
Explanation:
Different states of matter can be mixed without making a chemical change which makes it a mixture
Answer:
There are 18572.9 arcminutes in 86% of a circle.
Explanation:
The degrees in 86% of a circle is:
Now, we need to find the number of arcminutes in 309.6°:
Therefore, there are 18572.9 arcminutes in 86% of a circle.
I hope it helps you!
Answer:
1.20atm
Explanation:
Given parameters:
Partial pressure of gas 1 = 0.35atm
Partial pressure of gas 2 = 0.20atm
Partial pressure of gas 3 = 0.65atm
Unknown:
Total pressure of the gas mixture = ?
Solution:
To solve this problem, we need to recall and understand the Dalton's law of partial pressure.
Dalton's law of partial pressure states that "the total pressure of a mixture of gases is equal to the sum of the partial pressure of the constituent gases".
Total pressure =Pressure of gas(1 + 2 + 3)
The partial pressure is the pressure a gas would exert if it alone occupied the volume of the gas mixture.
Now we substitute;
Total pressure = (0.35 + 0.20 + 0.65)atm = 1.20atm
In studying effects of collisions between galaxies, astronomers usually make use of space telescopes.
Astronomy deals with the study of outer space. The study focuses on planets and other celestial bodies. Generally telescopes are used to study outer space. The particular type of telescope that is used depends on the need.
