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

What is the Golden Rule of Solubility? A. polar dissolves nonpolar. B. nonpolar dissolves polar. C. like dissolves unlike D. lik

DerKrebs [107]

Answer: D. like dissolves like

Explanation:

The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Hydrocarbons are non polar in nature due to less difference between the electronegativities of carbon and hydrogen and thus are soluble in non polar solvents only.

Ionic compounds which are formed by elements with high electronegativity difference are polar in nature and thus dissolve in polar solvents.

Example: $NaCl$ in water.
