Windblown sand can wear away rock
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
Becuz the sun refelt off the earth and on to the moon.
Answer:
Yes it is hard. For some of us. I already gave up, but now hes coming back. Id say sometimes its useless to get his attention if he never even pays attention to you anyways. It sucks because its so hard to get then to notice you for once.

Answer:
Kc for this reaction is 0.43
Explanation:
This is the equilibrium:
N₂(g) + 2H₂O(g) → 2NO(g) +2H₂(g)
And we have all the concentration at equilibrium:
N₂: 0.25M
H₂ : 1.3M
NO: 0.33M
H₂: 1.2M
They are ok, because they are in MOLARITY. (mol/L)
Let's make the expression for Kc
Kc = ( [NO]² . [H₂]² ) / ([N₂] . [H₂O]²)
Kc = (0.33² . 1.2²) / (0.25 . 1.2²)
Kc = 0.4356
In two significant digits. 0.43
