Contrast ionization energy from electron affinity.

Chemistry
1 answer:
inessss [21]3 years ago
8 0

Answer:

Ionization energy : energy required to take out an electron from the valance orbital of an atom.

Electron affinity: electron affinity of an atom measures the amount of energy released when an electron is forcibly entered or pushed into the valence orbital of an atom.

Ionization energy is the energy required to make an atom into a positive ion. Electron affinity is the energy released when an atom becomes a negative ion.

ionization energy is what is required to remove one electron from a normal gaseous atom to produce a +1 anion of that atom.

electron affinity is the energy required to remove one electron from a gaseous -1 anion of an atom to produce a normal gaseous atom.

Write the equation for the reaction described: A solid metal oxide, Ag2O, and hydrogen are the products of the reaction between
Harlamova29_29 [7]

Answer:

2Ag + H2O -----> Ag2O + 2H

Explanation:

2Ag + H2O -----> Ag2O + 2H is the equation of the reaction between metal and steam. Silver reacts with water (steam) forming silver oxide and hydrogen gas. When the metals react with steam it produces the solid metal oxide and hydrogen gas. On the surface o metals, a protective layer of aluminium oxide is formed that keeps water away from the metal so we can say that silver oxide and hydrogen are formed from the reaction of silver metal and steam.

The molar heat of fusion for water is 6.01 kJ/mol. How much energy must be added to a 75.0-g block of ice at 0°C to change it to
andreyandreev [35.5K]
Answer is: 25,06 kJ of energy must be added to a 75 g block of ice.
ΔHfusion(H₂O) = 6,01 kJ/mol.
T(H₂O) = 0°C.
m(H₂O) = 75 g.
n(H₂O) = m(H₂O) ÷ M(H₂O).
n(H₂O) = 75 g ÷ 18 g/mol.
n(H₂O) = 4,17 mol.
Q = ΔHfusion(H₂O) · n(H₂O)
Q = 6,01 kJ/mol · 4,17 mol
Q = 25,06 kJ.
