Answer:
The answer to your question is b. Mg is being oxidized and c. Mg is the
reducing agent.
Explanation:
Reduction is the gain of electrons
Oxidation is the loss of electrons
Reducing agent is the element that oxidizes itself and reduces another element.
Oxidizing agent is the element the reduces itself and oxidizes another element.
In this reaction:
Magnesium loses electrons so it is being oxidized and it is the reducing agent.
The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as
dn=70.7kg
<h3>What is the enthalpy change for the reaction?</h3>
Generally, the equation for the Chemical reaction is mathematically given as
2k+s----->K2S
Therefore
KS+K----->K2S
Therefore
dn=dn1+dn2
dn=32.5+38.2
dn=70.7kg
In conclusion, the enthalpy change is
dn=70.7kg

N2 is a diatomic molecule as it is composed of 2 atoms of the same element, covalently bonded to each other in this case Nitrogen.
B.) absorb energy as it goes to the ground state
Fe(NO3)2=0
Fe+2(+3+3*-2)=0
Fe+2*-3=0
Fe=-(-6)
Fe=+6
So, Fe=+6, N=+3, O=-2
