D.)good conductor of electricity
Explanation:
One very important property of gold is that is a good conductor of heat and electricity.
All known metals are able to act as good conductors of electricity and heat due to the presence of a large pool of free mobile electrons in them.
Gold is a metal and it is not an exception. Like other metals, gold is not rigid but ductile.
It contains metallic bonds between its particles and is able to move electric currents.

1.) is157.7 g
<span>moles Fe = 209.7 g/ 55.847 g/mol=3.75
the ratio between Fe and CO is 2 : 3
moles CO = 3.75 x 3 /2 =5.63
mass CO = 5.63 mol x 28.01 g/mol=157.7 g
