Answer: 3.5 moles
Explanation:
For every 2 moles of sulfur consumed, there are 3 moles of oxygen consumed.
This means that sulfur is the limiting reactant, meaning that 2(3)=6 moles of oxygen will be consumed.
Thus, 9.5-6=3.5 moles of oxygen will remain.

The chemical formula for calcium hydroxide is Ca(OH)₂ and that of nitric acid is HNO₃. By these chemical formula it can be deduced that the number of equivalents per mole of Ca(OH)₂ is 2 because of 2 OH⁻ and for HNO₃ is 1 because of H⁺.
For the neutralization reaction, the number of equivalents should be equal.
V₁n₁ = V₂n₂
Substituting the known values and with the incorporation of the concept above,
(V₁)(0.0250 mol/L)(2 equivalents/mol) = (33.50 mL)(0.020 mol/L)(1 equivalent/mol)
V₁ = 13.4 mL
Hence, the volume of calcium hydroxide needed is approximately equal to 13.4 mL.
The correct Lewis structure for carbon tetrabromide (CBr4), in which a central carbon atom is bound to four atoms of the group 7A element bromine would be one that a carbon having two electrons at the top, below, left and right and in every pair of electrons a bromide atom is present sharing the electrons.
The Earth's structural zones (S-Zones) are the lithosphere, asthenosphere, mesosphere, inner core, and outer core.
