Vegetable soup is the one among the following options given in the question that is not a homogeneous mixture. The correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer you were looking for and it has helped you.
Everyone of us knows that there was an Intense Volcanic activity for the first billion year of Earth. Due to the circumstances, the amount of gases in our atmosphere was very unsupportable for existence of life(Very similar like the atmosphere of Mars & Venus of today).
Amount of Carbon dioxide was most abundant whereas oxygen was very little. Then, the changes which affect the proportion of gases were:
1) For Increasing Oxygen. - The only and most important source of increasing oxygen was the "Photosynthesis by Plants".
2) For decreasing Carbon dioxide. - (i) Absorbed by plants in order to do the process of photosynthesis.
(ii) Most of the CO2 dissolved in Oceans and many locked in <span>sedimentary rocks, such as limestone, and in fossil fuels.
In that way, Our Atmosphere evolved,and now we're able to survive (If we care about our environment)
Hope this helps!</span>

<u>Rules to write the electronic configuration
:</u>
Electrons complete orbitals in a way to reduce the energy of the atom. Therefore, the electrons in an atom complete the principal energy levels in order of rising energy (the electrons are getting distant from the nucleus). The order of levels filled appearances like the following
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p
One way to recognise this pattern, apparently the simplest, is to refer to the periodic table and remember where each orbital block drops to rationally understand this pattern. Different way is to make a table like the one below and use vertical lines to determine which subshells resemble with each other.
- S block: The S obstruct in the periodic table of components known as gatherings 1 and 2. There is a limit of two electrons that can possess the s orbital.
- P Block: The P square contains group of 13, 14, 15, 16, 17, and 18, except for Helium.
- D Block: The D block elements are found in groups 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 of the periodic table.
<span>This question cannot be answered in actual centimeters unless at least one edge has a known length however it can be written as (length^3) or (length cubed). As an example if the sample of gold cube had one length of 3cm then all lengths would be 3cm on the cube.</span>
