Gold is an element
Sulfur is an element and therefore homogeneous.
Sodium hydroxide is a chemical compound.
Pure quartz is a homomogeneous crystal.
Yes, water with ice cubes is heterogeneous because it is a combination of two distinct phases - liquid water and solid ice. The ice cubes do not completely dissolve in the water, leading to a visible separation of the two components.
Humans, or Homo sapiens, belong to the genus Homo and have been present on Earth for around 300,000 years. They are believed to have evolved from earlier species of hominids, such as Homo erectus and Homo habilis. The exact order of appearance of different Homo species is still a subject of research and debate among scientists.
