Detergents are amphipathic molecules that contain polar or charged hydrophilic groups (heads) at the end of long lipophilic hydrocarbon groups (tails) (Figure 1). They are also known as surfactants because they decrease the surface tension of water.
The IUPAC name of the compound <span>ch3–ch2–c ≡ c–ch3 is
PEN-2-YNE or
2-PENTYNE.

Complete combustion of an alkane (methane)
You're essentially burning CH4 in the excess presence of oxygen gas, which results in the liberation of water and carbon dioxide
Answer:
Percent yield = 87.5%
Explanation:
Given data:
Number of moles of Fe(NO₃)₃ = 2.5 mol
Number of moles of Na₂CO₃ = 3.6 mol
Actual yield of NaNO₃ = 6.3 mol
Percent yield of NaNO₃ = ?
Solution:
Chemical equation:
2Fe(NO₃)₃ + 3Na₂CO₃ → Fe₂(CO₃)₃ + 6NaNO₃
now we will compare the moles of both reactant with NaNO₃.
Fe(NO₃)₃ : NaNO₃
2 : 6
2.5 : 6/2×2.5 = 7.5
Na₂CO₃ : NaNO₃
3 : 6
3.6 : 6/3×3.6 = 7.2
Theoretical yield of NaNO₃ is 7.2 mol.
Percent yield:
Percent yield = actual yield / theoretical yield ×100
Percent yield = 6.3 mol / 7.2mol ×100
Percent yield = 87.5%
