Answer:
The d-block elements are all metals and most have one or more chemically active d-orbital electrons. Because there is a relatively small difference in the energy of the different d-orbital electrons, the number of electrons participating in chemical bonding can vary.
Combustion! CH4, which is methane, reacts with oxygen to form carbon dioxide. (For future reference, if a compound is reacted with ONLY oxygen it is sure to be a combustion reaction)
Answer:
15.41.
Explanation:
- From the balanced equation:
<em>2SO₂(g) + O₂(g) ⇄ 2SO₃(g).</em>
<em />
The equilibrium constant = Keq = [SO₃]²/[SO₂]²[O₂].
<em>∴ Keq = [SO₃]²/[SO₂]²[O₂]</em> = (0.56 mol/L)²/(0.344 mol/L)²(0.172 mol/L) = <em>15.41.</em>
The correct answer of gibbs free energy is -232 KJ.
ΔG = -nFE° = -2*96485*1.20 = -232 (kJ)
The Gibbs free energy of a system at any point in time is defined as its enthalpy minus the product of its temperature times its entropy. Because it is defined in terms of thermodynamic properties that are state functions, the system's Gibbs free energy is a state function. It is commonly referred to as free energy because it is readily available at all times. If necessary, the reaction can steal this energy without having to pay or work for it. The reaction between sodium chloride and water is regarded as spontaneous, and it has a negative G. When solid NaCl is immersed in water, it begins to dissociate on its own without any external assistance.
