Explanation:
Hello,
In this case, one can assume that the the solubility in hexane for O is 0.225 g/mL as it's common for organic compounds, thus, the maximum mass that is completely dissolved into 10.0 L of hexane (that will be the solution's volume) is found via:
Best regards.
Answer:
116 °C
Explanation:
The given parameters of the Substance Q are;
The boiling point of Q = 445°
The substance <em>Q</em> is a solid at room temperature
Given that <em>Q</em> has a single fixed boiling point, <em>Q</em>, is suspected to be a pure substance, and it will therefore also have a fixed single melting point above room temperature;
Therefore, the best option is option C. 116 °C, which is above a single temperature value above 116 °C
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
