What is the balanced equation for the combustion of sulfur

Chemistry
1 answer:
Alex17521 [72]3 years ago
3 0

Answer:

There are three possible chemical equations for the combustion of sulfur:

  • 2S (s)  + O₂ (g)  → 2SO (g)

  • S (s) + O₂ (g) → SO₂ (g)

  • 2S (s) + 3O₂ (g) → 2SO₃ (g)

Explanation:

<em>Combustion</em> is a reaction with oxygen. The products of the reaction are oxides, and energy is released in the form of heat and light.

<em>Sulfur</em> iis a nonmetal, so the oxide formed is a nonmetal oxide.

The most common oxidation numbers of sulfur are -2, + 2, + 4, and + 6.

The combination of sulfur with oxygen may be only with the positive oxidation numbers (+2, + 4, and +6).

Then you have three different equations for sulfur combustion:

<u>1) Oxidation number +2:</u>

  • S(s) + O₂(g) → SO(g)

Which when balanced is: 2S(g) + O₂(g) → 2SO(g)

<u>2) Oxitation number +4:</u>

  • S(s) + O₂(g) → SO₂(g)

That equation is already balanced.

<u>3) Oxidation number +6:</u>

  • S(s) + O₂(g) → SO₃(g)

Which when balanced is: 2S(s) + 3O₂(g) → 2SO₃(g)

One problem with elimination reactions is that mixtures of products are often formed. For example, treatment of 2-bromo-2-methyl
NikAS [45]

Answer:

Structures are given below.

Explanation:

  • Treatment of 2-bromo-2-methylbutane with KOH in ethanol will give elimination of HBr through E2 mechanism.
  • H atoms adjacent to Br will be eliminated.
  • 2-bromo-2-methylbutane has two possible adjacent H atoms that can be eliminated giving mixture of products.
  • Product of this elimination reaction is alkene. Here saytzeff fule is followed during elimination. So most substituted alkene will be major product.
  • Structure of alkenes are given below.

A certain voltage is applied to a copper wire and to a germanium wire of the same thickness and length. how will the current in
Elena-2011 [213]
Answer : The current will flow more easily and quickly through the copper wire, on application of voltage because copper is a metal which is good conductor of heat and electricity.

In case of germanium it is a semi-conductor means it will behave as a conductor under certain circumstances.

So if we take same length and same thickness of both the wires, current is more likely to flow through the copper wire than the germanium wire.

How many moles of CuSO4 are used to make 250 ml of a 0.50 M CuSO4 solution?
xz_007 [3.2K]
In order to prepare a 250 ml solution of CuSO₄ of 0.5 M we need to calculate the amount of CuSO₄ requires. So, as we know,

                      Molarity  =  Moles / Volume of Solution
Also, 
                      Molarity  =  (Mass ÷ M.mass) / Volume of Solution

Solving for Mass,

                      Mass  =  Molarity × M.mass × Volume

Putting Values,                                                  ∴ 250 ml  =  0.25 dm³
     
                      Mass  =  0.5 mol.dm⁻³ × 159.6 g.mol⁻¹ × 0.25 dm³

                      Mass  =  19.95 g

Step 2:
            
Take 19.95 g of CuSO₄, add it to volumetric flask and add distilled water upto the mark of 250 ml. The resulting solution will be of concentration 0.5 M.
