Answer: -
The chemical formula of Antimony(III) sulfide = Sb₂S₃
Mass of Sb produced = 175.6 g
Molar mass of Sb = 121.76 g /mol
Number of moles of Sb = 175.6g / (121.76 g/mol)
= 1.44 mol
The balanced chemical equation for this reaction is
Sb₂S₃ + 3 Fe → 2 Sb + 3 FeS
From the chemical equation we see
2 mol of Sb is produced from 1 mol of Sb₂S₃
1.44 mol of Sb is produced from 
= 0.72 mol of Sb₂S₃
Molar mass of Sb₂S₃ = 2 x 121.76 + 32.06 x 3
= 339.7 g / mol
Mass of Sb₂S₃ = 0.72 mol x 339.7 g/ mol
= 244.58 g
= 244.6 g rounded off to 4 significant figures.
Answer: The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
