<span>For resonance forms of a molecule or ion, the observed structure is an average of the resonance forms. Sometimes it also depends on how the ion or molecule interact with neighboring molecule or ion. In physics, resonance</span><span> is described as when a vibrating system or external
force drives another system to oscillate with greater amplitude at a specific
preferential frequency. </span><span>It is not that one structure always corresponds to the observed structure because they will not exist if it is drawn. It is not the same atoms that do not need to be bonded to each other of the resonance structure because it is describing the migration of the atoms not the species itself. </span>
Answer:
a) = 0.704%
b) = 1.30%
c) = 2.60%
Explanation:
Given that:
=
For Part A; where Concentration of A = 0.270 M
Percentage Ionization(∝)
percentage% (∝) =
= 0.704%
For Part B; where Concentration of B = M
percentage% (∝) = 0.0130 × 100%
= 1.30%
For Part C; where Concentration of C=
percentage% (∝) = 0.02608 × 100%
= 2.60%
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

Answer:
D) burning a candle
A demonstration that contains both physical and chemical changes will be BURNING OF A CANDLE.
<em>This is because when a candle is lighted up, on the top of it (where we see flame) the oxygen and other gases present around will be chemically changed (burned up)</em>
<em>When the wax in the top of the candle will get melted due to the heat of the fire a physical change takes places.</em>
