lemme know if right if not sorry :))
Answer: The enthalpy change for this reaction is 392 Joules
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
Now put all the given values in this expression, we get
Therefore, the enthalpy change for this reaction is 392 Joules
As in relative abundance , one is take reference
So,
One is taken as 1:
Other is subtracted from it:
(1 - 0.6011)(atomic mass of Ga-71)
Equation can be written as:
<span>69.723 = (0.6011)(68.9256) + (1-0.6011)x </span>
<span>(1-0.6011) is the percentage abundance of Ga-71 expressed in percentage: </span>
<span>Solving for x </span>
<span>28.2918 = 0.3989 x </span>
<span>x= 70.9246.......</span>
Explanation:
Octahedral complexes will be favoured over tetrahedral ones because:
It is more favourable to form six bonds rather than four
The crystal field stabilisation energy is usually greater for octahedral than tetrahedral complexes.
The transition metals Co, Rh, Lr are in group 9 of d block and they have 3d, 4d, and 5d orbitals respectively
A, the higher the temperature, the faster the average kinetic energy
