Answer:

Iron displaces copper ions

Explanation:

which means that iron in more reactive than copper.

The enthalpy of fusion of H2O (s) at its normal melting point is 6.01 kJ/mol. What is the entropy change for freezing 1 mole of
Rom4ik [11]

Answer:

22.01J/Kmol

Explanation:

The parameters given in this question are;

Enthalpy (H) = 6.01 kJ/mol.

Number of moles = 1

Entropy change (S) = ?

The formular relationship between entropy and enthalpy is given as;

ΔS=ΔH/T

Temperature for water at freezing point = 0C + 273 = 273 K (converting to Kelvin)

ΔS = 6.01/273

ΔS = 0.0220kJ/Kmol

ΔS = 0.02201 * 1000 = 22.01J/Kmol

Answer:

Correct answer is A, they regulated the ticking of the clock...

Explanation:

The atomic clock uses a more fundamental vibration, and it uses it as part of a self-regulating system. A crystal of quartz has two properties that help it keep time.

The atoms serve the same purpose as did pendulums or quartz crystals in earlier clocks. They have no “hands” to turn or liquid crystal displays for number read-outs. They simply produce electrical pulses that serve as a standard for calibrating other less accurate clocks.
