Answer is: empirical formula is Cu(C₂H₃O₂)₂ · H₂O.
If we use 100 grams of compound:
m(Cu) = 0,3182 · 100 g = 31,82 g.
n(Cu) = m(Cu) ÷ M(Cu).
n(Cu) = 31,82 g ÷ 63,55 g/mol.
n = 0,5 mol.
m(C₂H₃O₂) = 0,5914 · 100 g = 59,14 g.
n(C₂H₃O₂) = 59,14 g ÷ 59,14 g/mol.
n(C₂H₃O₂) = 1 mol.
m(H₂O) = 100 g - 59,14 g - 31,82 g = 9,04 g.
n(H₂O) = 9,04 g ÷ 18,02 g/mol.
n(H₂O) = 0,5 mol.
n(Cu) : n(C₂H₃O₂) : n(H₂O) = 0,5 mol : 1 mol : 0,5 mol.
n(Cu) : n(C₂H₃O₂) : n(H₂O) = 1 : 2 : 1.

alexgriva [62]

Explanation:

Gold conducts heat and electricity. ...

Gold is ductile: It can be drawn out into the thinnest wire. ...

Gold is highly reflective of heat and light. ...

Gold is prized for its beauty. ...

Gold is malleable, so it can be flattened into extremely thin sheets.

on the other hand Gold consist of copper

Key Properties of Copper Alloys

Excellent heat conductivity.

Excellent electrical conductivity.

Good corrosion resistance.

Good biofouling resistance.

Good machinability.

Retention of mechanical and electrical properties at cryogenic temperatures.

Non-magnetic.

so the difference is that copper is less expensive and not priced with its beauty

Explain how hydrogen bonding contributes to water's high heat of vaporization
pashok25 [27]

The heat/enthalpy of vaporization of water represents the energy input required to convert one mole of water into vapor at a constant temperature. Intermolecular forces including hydrogen bondings of significant strength hold water molecules in place under its liquid state. Whereas the molecules experience almost no intermolecular interactions under the gaseous state- consider the way noble gases molecules interact. It is thus necessary to supply sufficient energy to overcome all intermolecular interactions present in the substance under its liquid state to convert the substance into a gas. The heat of vaporization is thus related to the strength of the intermolecular interactions.

Water molecules contain hydrogen atoms bonded directly to oxygen atoms. Oxygen atoms are highly electronegative and take major control of electrons in hydrogen-oxygen bonds. Hydrogen atoms in water molecules thus experience a strong partial-positive charge and would attract lone pairs of electron on neighboring water molecules. "Hydrogen bonds" refer to the attraction between hydrogen atoms bonded to electronegative elements and lone pairs of electrons. The hydrogen-oxygen bonds in water molecules are so polarized that hydrogen bonds in water are stronger than both dipole-dipole interactions and London Dispersion Forces in most other molecules. It thus take high amounts of energy to separate water molecules sufficiently apart such that they no longer experience intermolecular interactions and behave collectively like a gas. As a result, water has one of the highest heat of vaporization among covalent molecules of similar sizes.
