The three of them have the same amount of electrons, so we can’t determine the right one on that ground. As you might know, Pauli said that electrons are always in the position of the lowest energy. So the first situation is impossible because there is a free place available that takes less energy. Then the 3rd situation is nor possible because if one electron has a different spin than the others, there is a magnetic obstruction that be prevented if the spin changes. This means that the second situation is the right one.
Answer:
Sugar
Explanation:
Mixtures are substances that made of two or more elements or other substances that are joined together by physical methods and when mixed can be also be separated by physical method into the original individual elements.
Air is a mixture of gases such as oxygen, nitrogen, carbon dioxide and rare gases. When an amount of air is collected, its constituents can be collected separately.
Likewise 7 up and sea water
Sugar is a compound made of carbon, hydrogen and oxygen, when sugar is decomposed, it's original constituents are not recovered but sugar is decomposed into carbon dioxide and water
Answer:
Rubidium
Explanation:
Rubidium is an alkali metal that has 37 protons 48 neutrons and 1 valence electron
If you are wanting the equation to be balanced it would be: P4 + 6Cl2 → 4PCl3
Answer:
Explanation:
Hello!
In this case, since the melting process involves the heat added to the system, the heat of fusion and the mass of water:
Thus, as it has been reported that the heat of fusion of ice is 333.6 J/g, we can compute the melted mass of ice as shown below:
Thus, the ice leftover results:
