Gold is an element
Sodium hydroxide is a chemical compound.
Sulfur is an element and therefore homogeneous.
Pure quartz is a homomogeneous crystal.
no, hetero= not the same, homo = the same H20 (water) + more H20 (ice) is homogeneous, the states don't affect the mixture..
In the broadest sense, there was no "first person", even if we only ask who was the first person who was a modern human, a member of Homo sapiens. This is because we could not say definitively that this person was finally a Homo sapiens,but that his or her parents were still Homo erectus. Evolution is simply too gradual for such simple answers. What we do know is that the first Homo sapiens evolved over two hundred thousand years ago.We could regard our Homo erectus ancestors as people, although not yet modern humans, or even their Homo habilisancestors as people. Many scientists regard their more ancient predecessors as too primitive and too different to really be people in the sense that we usually use the word. So there would be a broad consensus that Homo habilis were the first people on earth.
A pure element or a pure compound are homogeneous.
Aluminium is a chemical element.
Maple syrup is a homogeneous mixture.
Ammonia is a compound, not a gas.
Sugar (sucrose) is a compound not a mixture.
Copper is a chemical compound not a mixture.
Nitrogen is a chemical element not a mixture.
Sodium hydroxide is a chemical compound.
Sugar (sucrose) is a chemical compound not mixture.
Sodium chloride is a chemical compound, not a mixture.
Due to dust particles and dissolved gases in the droplets of rain it is a heterogeneous mixture.
Aluminium is an element, not a mixture.
