Answer:
By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.

Sorry only knew the answer to the first question
Answer:
Density of the solid=
Explanation:
We are given that
Mass of sample of metal=4.369 g
Volume in the flask, V=126.4 ml
Mass of water, flask, and metal=268.5 g
Mass of flask=139.3 g
Density of water=1.000 g/mL
We have to find the density of the solid.
Mass of water=268.5-4.369-139.3=124.831 g
Volume of water=
Volume of water=
Volume of solid=126.4 ml-124.831 mL
=1.569mL
Now,
Density of the solid=
=
1mL=1 cubic cm
Therefore,
Density of the solid=

i think
Explanation:
A calcium ...... i believe this is the answer
If you are looking for a one specific electron you will have 90% chance of finding it in an area within the atom electron clouds.
According to the wave mechanical or electron cloud model of the atom, postulates that the atomic orbital is a region in space where there is a very high probability of finding an electron.
The term "electron cloud" is just another term used for "atomic orbital".
Since electrons reside in orbitals, if you are looking for a one specific electron you will have 90% chance of finding it anywhere within the electron clouds. This would make mathematical sense as the probability of finding an electron within the electron cloud can never be 100%.
