Answer:
-205.7kj
Explanation:
Now adding reaction 2 and twice of reaction 3 and reverse of reaction 1, we get the enthalpy of the reaction.
The expression for enthalpy for the following reaction will be,
where,
n = number of moles
Now put all the given values in the above expression, we get:
Therefore, the enthalpy of the following reaction is, -205.7kj
Answer:
2.6166 moles
Explanation:
stp means: T=273k p=101.3kpa
R= 8.31(constant) v=58.6
using the ideal gas law; pv=nRt
101.3 x 58.6 = n x 8.31 x 273
n= (101.3 x 58.6)\(8.31 x 273)
n= 2.6166moles

Answer:. an ionic compound
Explanation:
If it conducts electricity when molten, then it is an ionic compound. No covalent compound conducts electricity in molten state because their crystal lattice is not composed of ions. There are ionic solids which conduct electricity when molten but are insoluble in water such as alumina Al2O3. The solid is soluble in strong acid solutions.
