Answer:
There are 342 g/ 95. 2 g/m = 3.59 moles
Explanation:
MgCl2 → Molar mass is 95.2g g/m
This is the mass in one mol so to find out the moles in 342g we have to divide the mass between the molar mass.
342 g/ 95. 2 g/m = 3.59 moles
Unsaturated hydrocarbons are those in which each carbon atom is attached to as many hydrogen atoms as it possibly can. There can be no double bonds or non-hydrogen functional groups, since these detract from the maximum possible number of hydrogens that each carbon can be attached to (in the case of double bonds, two carbons are bonded to each other when they could alternately be bonded to one more hydrogen each).
All of the alkanes (including the cycloalkanes) are saturated hydrocarbons. Substituted alkanes, alkenes, alkynes, and their cyclic counterparts are all unsaturated.
Answer:
<u>Reaction is called exergonic when ΔG is negative i.e. ΔG < 0</u>
Explanation:
The Gibbs free energy represents the spontaneity or feasibility of a given chemical reaction at constant pressure and temperature and is given by the equation:
ΔG = ΔH - TΔS
Here, ΔG - change in the Gibbs free energy
ΔS - change in the entropy
ΔH - change in the enthalpy
T - temperature
If the value of <u>ΔG for a chemical reaction is positive i.e. ΔG > 0</u>, then the given chemical reaction is said to be nonspontaneous. Such a reaction is called endergonic.
Whereas, if the <u>ΔG value for a chemical reaction is negative i.e. ΔG < 0</u>, then the given chemical reaction is said to be spontaneous. Such a reaction is called exergonic.
