So,
Ionic compounds are compounds composed of ions. The following are soluble ionic compounds (they dissolve in water):
NaCl(s) --> Na⁺(aq) + Cl⁻(aq)
NaOH(s) --> Na⁺(aq) + OH⁻(aq)
The following are insoluble ionic compounds (they have low solubilities):
Al₂O₃ --> 2Al³⁺+3O²⁻
AgCl --> Ag⁺ + Cl⁻
These compounds can only be appreciably separated by melting or by dissolving them in enormous amounts of water (the concentration will still be very low).
Ionic compounds have electrons that are locked in place because of the strong ionic attractions between the ions. A charge is produced by moving electrons. Since the ions in melted ionic compounds are free to move, their electrons are no longer locked, allowing the ionic liquid to conduct electricity.
NaCl(s) --> Na⁺(l) + Cl⁻(l)
The answer is D.

Answer:
The specific heat of iron is 0.45 J/g.°C
Explanation:
The amount of heat absorbed by the metal is given by:
heat = m x Sh x ΔT
From the data, we have:
heat = 180.8 J
mass = m = 22.44 g
ΔT = Final temperature - Initial temperature = 39.0°C - 21.1 °C = 17.9°C
Thus, we calculate the specific heat of iron (Sh) as follows:
Sh = heat/(m x ΔT) = (180.8 J)/(22.44 g x 17.9°C) = 0.45 J/g.°C
The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.
<h3>What are CAM?</h3>
CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.
In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.
Hence option (C) is correct.
