Answer:
It increases when the temperature increases.
Explanation:
- According to Arrhenius relation: k = Ae(-Ea/RT).
- The rate constant of the reaction and also the rate of the reaction increases exponentially with increasing the temperature of the reaction.
- As the temperature increases, the no. of molecules that can posses the critical energy (activation energy) to initiate the chemical reaction and pass the energy barrier increases.
The electron configuration of a calcium ATOM would be
But, the calcium ION has two electrons less than a calcium atom.
The electron configuration of a calcium ION should be the same as Argon since a calcium ion is missing 2 electrons.
Your answer is
Have an awesome day! :)
Substance x is known to exist at 1 atm in the solid, liquid, or vapor phase, depending on the temperature, is mathematically given as
Q=800J.mol^{-1}
<h3>What is a graph of the other properties of x?</h3>
Generally, the equation for heat absorbed is mathematically given as
Q= Heat capacity of solid *T
In conclusion,
Q= (40)(293.15-273.15)
Q=800J.mol^{-1}
In conclusion, Because the enthalpy of fusion is 9 KJmol-1 and we are only providing 6 KJmol-1 of heat, the melting process will not be complete. the graph is attached.
CQ

#SPJ1
Explanation:
The given data is as follows.
mass = 0.158 g, volume = 100 ml
Molarity = 1.0 M, =
The given reaction is as follows.
So, moles of magnesium will be calculated as follows.
No. of moles =
=
=
= 0.0065 mol
Now, formula for heat released is as follows.
Q =
=
=
= 3010.32 J
Hence, heat of reaction will be calculated as follows.
=
= -4.63 J/mol
or, = (as 1 kJ = 1000 J)
Thus, we can conclude that heat of given reaction is kJ/mol.
Nuclear fusion
Explanation:
For a given mass, the energy released is greatest for a reaction involving nuclear fusion.
Nuclear reactions generally release far much more energy compared to chemical energy because they involve the interaction between strong nuclear forces. There are two main types of nuclear reactions which are fusion and fission.
Nuclear fusion powers the sun and releases the greatest amount of energy.
- In nuclear fusion, light atoms combines to form heavier ones.
- The reaction degenerates into chain reaction in which huge amount of energy is released.
- This reaction occurs in the core of sun and furnishes the solar system with radiant energy.
