During the 1830s, Giuseppe Mazzini had sought to put together a coherent programme for the unitary Italian Republic. He had also formed a secret socie...
(c) 4 Explanation: pH = -log [H+] = -log 10-4 = -(-4) log 10 = 4
(d) +4 Explanation: CH3COOH + C2H5OH → CH3COOC2H5 + H2O At start 1 mole 1 mole 0 0 At equb. 1- 2/3 1- 2/3 2/3 2/3 Let the...
(c) 5.3 Explanation: pH value of ordinary water is about 5.3 because some CO2 from atmosphere dissolves in pure water to form H2CO3 (carbonic acid...
(a) <1.2 x 10-2 Explanation: For the given reaction, 2H2S(g) ⇌ 2H2(g) + S2(g) Δn = 3 - 2 = 1 KC = Kp /(RT)n = 1.2 x 10-2/(RT)1 ∴ KC <...
(b) BF3 Explanation: In BF3, B is electron deficient because it has incomplete octet and thus can accept electron pair (Lewis acid).
(d) [C]/[A]3[B]2 Explanation: Equilibrium constant, K = [C]/[A]3[B]2
(c) I- Explanation: Here I- is Lewis base as it is giving electron to I2 molecule.
(c) If Assertion is correct but Reason is incorrect. Explanation: Assertion is true but reason is false. ΔH = ΔE + ngRT Δng = (1 + 3) - 2 ΔH...
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion. Explanation: In an isothermal process change...
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion. Explanation: The factor TΔS increases with i...
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion. Explanation: In an isothermal process change...
(c) If the Assertion is correct but Reason is incorrect. Explanation: For given reaction ΔH > ΔE because {ΔH = ΔE + ΔnRT}. In this reaction Δn(...
(c) If the Assertion is correct but Reason is incorrect. Explanation: In NaCl crystal Na+ and Cl- are strongly bonded due to electrostatic attract...
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion. Explanation: At room temperature water is m...
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion. Explanation: Molar heat of vaporisation of ...
(c) If the Assertion is correct but Reason is incorrect. Explanation: ΔH = ΔE + (RT)Δn If there is no change in the moles of reactants (gaseous)...
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion. Explanation: For all isothermal process cha...
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion. Explanation: Absolute values of internal en...
(c) If the Assertion is correct but Reason is incorrect. Explanation: The properties of a system which depend upon quantity of matter contained in...
