Liquid gold-homogeneous
Solid-heterogenous
18 karat gold is a homogeneous mixture. It consists of 75% gold and 25% other metals, such as copper and silver, which are uniformly distributed throughout the gold.
Gold is homogeneous, meaning composed of the same thing, / phase. like salt. Heterogeneous, composed of different. ie. ice + water
Gold is a single element (Au). And is thus homogeneous.
A mixture of gold and copper in a coin is considered a homogeneous mixture because the two metals are evenly distributed throughout the coin and cannot be easily separated.
24K gold is a pure substance but it is not suitable for making any items because it is too soft. Hence, we use copper or silver and mix it with 24K gold and make it 22K gold which is hard enough to be used. It is a mixture

Gold is metal that is a homogenous mixture. It is not a heterogeneous mixture, because a heterogeneous mixture can be physically separated.
This is an alloy and a homogeneous mixture.

Gold is a pure element, not a mixture of any kind.White gold (alloy with nickel, manganese, or palladium) is a homogeneous mixture because you can't see the separate substances that are in it. Therefore it is a homogeneous mixture.
Gold is a single element (Au). And is thus homogeneous.
A mixture of gold and copper in a coin is considered a homogeneous mixture because the two metals are evenly distributed throughout the coin and cannot be easily separated.
Since gold is an element and therefore a pure substance it is homogeneous.

Homogeneous mixtures are the all the same (homo = same). Heterogeneous mixtures have different parts (hetero = different). Think of it as you could separate heterogeneous mixtures with tweezers, like a pizza, while silly putty is all together and you cant separate it like that. Therefore, because Au is the atomic symbol for gold, an element, it must be homogeneous. Hope this helps!
Oh, dude, a 14-karat gold is technically a homogeneous mixture because it's made up of gold and other metals that are evenly distributed throughout. So, like, all the atoms are hanging out together in a nice, uniform way. But hey, if you're not into chemistry, just remember that 14-k gold is the good stuff that makes you look fancy, whether it's homogeneous or heterogeneous!
