Carbon disulfide burns with oxygen to form carbon dioxide and sulfur dioxide in the following manner: cs2 + 3o2 → co2 + 2so2

what is the volume of sulfur dioxide (so2 gas), formed when 2 moles of carbon disulfide (cs2) are burned? the reaction is taking place at stp.

5.6 l
22.4 l
89.6 l
44.8 l

89.6 L.

Explanation:

CS₂ + 3O₂ → CO₂ + 2SO₂.

Using cross multiplication:

1.0 mole of CS₂ produces → 2.0 moles of SO₂.

2.0 mole of CS₂ produces → ??? moles of SO₂.

∴ The no. of moles of SO₂ produced = (2.0 mol)(2.0 mol)/(1.0 mol) = 4.0 mol.

∴ 4.0 moles of SO₂ occupy = (4.0)(22.4 L) = 89.6 L.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
