Answer:
= 100kJ
Explanation:
The reverse reaction's activation energy of a reaction is the activation energy of the forward reaction plus ΔH of the reaction:
Ea of forward reaction =75kJ
∆H = -175 kJ/mol
Ea of reverse reaction = 75 +(-175)
= 100kJ
Note that a reverse reaction is one which can proceed in both direction depending on the conditions.
Explanation:
element with atomic numbers 7 and 83 have 5 and 5 valence electrons
Answer:
3
three half-filled orbitals each capable of forming a single covalent Bond and an additional lone - pair of electrons
B. All atoms of silver have the same atomic number but different numbers of neutrons in the nucleus.
As the number of electrons added to the same principal energy level increases, atomic size generally
C. Decreases.
