We can identify bias and avoid thinking errors when evaluating online information when there is a certain degree of partiality in the way the information is given. The writer takes one side and doesn’t consider benefits of the other side/view.
We can identify bias and avoid thinking errors when evaluating online information by making our personal findings and research from other sources and then comparing the two.
Answer:
1.2×10^7 dm³
Explanation:
1 mole of sulfur dioxide weighs 64 grams, so 64 tonnes is 10^6 moles.
The reaction of interest is ...
2SO₂ +O₂ ⇆ 2SO₃
This reaction uses half as many moles of oxygen as of sulfur dioxide. That is, 5×10^5 moles of oxygen are required. That quantity will have a volume of ...
(5×10^5 mol)(24 dm³/mol) = 1.2×10^7 dm³ . . . volume of oxygen needed
The answer is A.
A mole is Avagadro’s number of atoms of a substance. My periodic table of the elements gives the Gram Atomic Mass of natural sulphur is 32.066 grams/mole. Therefore, 2.4 moles would have a mass of 76.96 gm
