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

Using the reaction below: 2 CO2(g) + 2 H2O(l) → C2H4(g) + 3 O2(g) ΔHrxn= +1411.1 kJ What would be the heat of reaction for this

maw [93]

Answer: d) -705.55 kJ

Explanation:

Heat of reaction is the change of enthalpy during a chemical reaction with all substances in their standard states.

$2CO_2(g)+2H_2O(l)\rightarrow C_2H_4(g)+3O_2(g)$ $\Delta H=+1411.1kJ$

Reversing the reaction, changes the sign of $\Delta H$

$C_2H_4(g)+3O_2(g)\rightarrow 2CO_2(g)+2H_2O(l)$

$\Delta H=-1411.1kJ$

On multiplying the reaction by $\frac{1}{2}$ , enthalpy gets half:

$0.5C_2H_4(g)+1.5O_2(g)\rightarrow CO_2(g)+H_2O(l)$ $\Delta H=\frac{1}{2}\times -1411.1kJ=-705.55kJ/mol$

Thus the enthalpy change for the given reaction is -705.55kJ
