Answer:
The percent yield of carbon disulfide is 78.8%
Explanation:
Percent yield of reaction = (Produced yield / Theoretical yield) . 100
5C + 2SO₂ --> CS₂ + 4CO
In the reaction 5 moles of C, produce 1 mol of CS₂
40 g / 12 g/m = 3.33 moles
Then, this is the rule of three:
5 mol of C produce 1 mol of CS₂
3.33 moles of C, will produce ( 3.33 .1)/5 = 0.666 moles
Mol . molar mass = mass → 0.666 mol . 76.12 g/m =50.7 g (Theoretical yield)
(40 g / 50.7 g) . 100 = 78.8%
Answer:
Option (D)
Explanation:
Chlorofluorocarbon is referred to as one of the important greenhouse gas, that is responsible for the depletion of the ozone layer. It was earlier extensively used in the refrigerators, but are later observed that as the CFC molecules are disintegrated in the atmosphere, it gives rise to the elimination of chlorine atoms that destroy the ozone layer, allowing the ultraviolet radiations to enter the earth's atmosphere. So, the use of CFCs has been banned globally by international treaties.
This gas is long-lasting, and remains in the atmosphere for about 20 to 100 years, is not that effective to human bodies, and present in the stratosphere in a very small amount.
Thus, the correct answer is option (D).
True because increasing the temperature it gets hotter
Answer:
What effects do wind patterns have on climate?
Explanation:
They move warm water toward the east. They change the amount of precipitation in an area and affect a region's climate.
