Explanation:
NH4OH(aq) ---> NH4+(aq) + OH-(aq)
Answer: No
Explanation:
A periodic table can be defined as the table in which the row of chemical elements are present. All the elements of the row have same number of electron shells.
The arrangement of elements is based on atomic numbers, electron shell model and other chemical properties. The elements are placed in increasing order of atomic number.
This table does not give information about the occurrence of the elements.
Covalent compounds are held together with an intra molecular attraction which is weaker than metallic bond
hence covalent compounds exist as liquids, gases and soft solids
The water of hydration is not covalently bound to the compound.
Many compounds, especially ionic compounds contain molecules of water of hydration which appears as part of the chemical formula of the compound.
This water of hydration is only attached to the crystal of the compound loosely. There is no chemical interaction between the water molecules and the crystal of the compound.
To prove this, the water of hydration is easily driven off by heating. It wouldn't have been possible to drive it off by heating if was covalently bonded to the compound.
Therefore, the water of hydration is not covalently bound to the compound.

Answer:
Explanation:
Hrxn = -245.6-296.8+396+50.0 = -96.4 (kJ/mol)
Since Grxn = Hrxn - T*Srxn, where T = 298.15K, we have:
Srxn = (Hrxn - Grxn)/T = (-96.4+75.2)× 1000÷298.15 = -71.1 (j/K mol)
Since: Srxn = Sf (SO2) + Sf (SOCl2)- Sf (SO3) - Sf (SCl2),
or: -71.1 = 248.1 + Sf (SOCl2) - 256.7-184,
Sf (SOCl2) = 256.7+184-71.1-248.1 = 121.5 (J/mol*k)
In order to find T such that Grxn = Hrxn - T*Srxn >= 0. since Hrxn is negative and Srxn is positive, Grxn will always be less than zero. Therefore there won't be a temperature point at which the reaction is going to be non-spontaenous
