Lewis base A. Provides H in water Bronsted-Lowry acid B. Provides OH - in water Arrhenius base C. Proton donor D. Proton accepto
1 answer:
Answer: E. Electron pair donor
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions
in water.
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
Hence, the correct statement is Lewis base is Electron pair donor.

Answer:
The work energy added to the gas is
W = -72.48472 kJ
Explanation:
For constant pressure process
Work is given W = p×
However dH = m× = 1875 J
For mass m, dQ = 2625 J
That is m×1875 = 2625 or m = 2625/1875 = 1.4 kg
Therefore work doneper unit mass of gas is -W = p×(v₂ - v₁)
but pv = RT therefore work done per unit mass = -R×(T₂ - T₁) = -R×ΔT and
ΔT = 180.4K
Work done = -1.4×0.287×180.4 = -72.48472 kJ
