A homogeneous object, is an object with the same composition throughout it's entire volume.
It's identical. (assuming that the object is homogeneous)
no its not
Yes it is, it is made from a mixture of the sodium salts of various fatty acids of natural oils and fats.
it is homogeneous
The ocean is a heterogeneous mixture. This means that it has a mix of other compounds and elements in it. The ocean has salt, little traces of iron, sulfur from vents and many other compounds.

It's identical. (assuming that the object is homogeneous)
No. If an object is homogeneous, then you can cut it up into a bazillion smaller pieces, and every piece has the same density as the original object had.
The motor oil is a homogeneous mixture even though it is not colorless. I can see an object through a thin layer of oil.
Iron coated with rust can be considered a heterogeneous object.
no its not
The density of cutted pieces is identical; of course this is valid only for a homogeneous material.
If the object is homogeneous, its center of mass is in its geometrical center. And if it is small compared to Earth, its center of gravity is, for all practical purposes, its center of mass.
No, it is heterogeneous as there are still pockets of air in the cake itself.
Yes, because it has only one phase which describes homogeneous mixtures in chemistry. Whereas, heterogeneous are has a lot of phases meaning you can see more that just 1 thing, object or element in the mixture
