Explanation:
Answer:
H₃PO₄(aq) ⇄ H₂PO₄⁻(aq) + H⁺(aq)
Explanation:
The phosphoric acid fuel cell (PAFC) employs phosphoric acid (H₃PO₄), a weak acid that dissociates in 3 steps, each with its acid dissociation constant.
H₃PO₄(aq) ⇄ H₂PO₄⁻(aq) + H⁺(aq) Ka1
H₂PO₄⁻(aq) ⇄ HPO₄²⁻(aq) + H⁺(aq) Ka2
HPO₄²⁻(aq) ⇄ PO₄³⁻(aq) + H⁺(aq) Ka3
Answer:
dont listen to the mainstream media since 50% is ran by the jews and they tend to be lying and deceiving people
Explanation:
Answer:
a) both substances are insoluble in water
b) both substances are soluble in ligroin
c) both substances suffer combustion, octane produces more CO₂ than hexene.
d) both substances are less dense than waterl, with hexene having the lowest density.
e) only hexene would react with bromine
f) only hexene would react with permanganate
Explanation:
a) both substances are non-polar and water is polar
b) both substances are non-polar and lingroin is non-polar
c) C₈H₁₈ + 17.5O₂ → 8CO₂ + 9H₂O
C₆H₁₂ + 9O₂ → 6CO₂ + 6H₂O
d) water = 997 kg/m³
ocatne = 703 kg/m³
hexene = 673 kg/m³
e) bromine test is used to detect unsaturations
f) permanganate test is used to detect unsaturations
