Mass of Sulphur dioxide : 256 g
<h3>Further explanation</h3>
Given
Reaction
S + O2 --> SO2 *
Required
Mass of Sulphur dioxide
Solution
mol of Sulphur (Ar=32 g/mol) :
mol = mass : Ar
mol = 128 : 32
mol = 4
From the equation, mol ratio S : SO2 = 1 : 1, so mol SO2 = 4
Mass of SO2 :
mass = mol x MW SO2
mass = 4 x 64
mass = 256 g
Explanation:
hydrogen + oxygen = water
Enantiomers is a type of structural isomerism. Two structures have the same chemical formula, but they differ in the arrangement of functional groups. The key characteristic of a pair of enantiomers is that, the two structures are mirror-images of each other. Example is the two isomers of 2-butanol shown in the picture.
