The density of the object is 0.467 36 g/cm³.
The mass of the object is 389.27 g.
The volume of the object is 832.92 cm³.
Density = mass/volume = 389.27 g/832.92 cm³ = 0.467 36 g/cm³

Answer:
There are three possible chemical equations for the combustion of sulfur:
- 2S (s) + O₂ (g) → 2SO (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>
Which when balanced is: 2S(g) + O₂(g) → 2SO(g)
<u>2) Oxitation number +4:</u>
That equation is already balanced.
<u>3) Oxidation number +6:</u>
Which when balanced is: 2S(s) + 3O₂(g) → 2SO₃(g)
Answer:
Equilibrium constant is 0.0873
Explanation:
For the reaction:
A + B ⇄ C
Equilibrium constant is defined as:
K = [C] / [A] [B]
concentrations in equilibrium of each reactant are:
[A] = 10 - X
[B] = 5 - X
[C] = 15 + X
If concentration in equilibrium of B is 9, X is:
[B] = 5 - X = 9 → <em>X = -4 </em>
Replacing:
[A] = 10 - (-4) = 14
[B] = 5 - (-4) = 9
[C] = 15 + (-4) = 11
K = 11 / (14×9) = 0.0873
Thus, <em>equilibrium constant is 0.0873</em>
