The amount of salt added to water does not affect the boiling point ot would stay at 100 degrees c or 212 degrees F
Explanation:
yes you got the right idea
Answer:
Explanation:
2 KCIO,(s) 2 KCI) + 3 02(g)
For every 3 moles of O2 you need 2 moles of KClO3
2/x = 3/15 Cross Multiply
3*x = 2 * 15 Combine the right
3x = 30 Divide by 3
3x/3 = 30/3 Combine
x = 10
Explanation:
Xenon is a noble gas element that is highly unreactive. It has completely filled outermost shell and very stable on its own.
Xenon is an element with an atomic number of 54; it has an electronic configuration below:
[Kr] 4d¹⁰ 5s² 5p⁶
As we can see, the outermost energy shell, level 5; has a configuration of:
5s² 5p⁶
S is a sublevel with 2 electrons made up of 1 orbital
P is a sublevel with 6 electrons made up of 3 orbitals
These orbitals are filled in xenon and so it is stable and will not want to react with any other kind of atom.
This is why it is unreactive.

Answer:
The number of valence electrons increases from top to bottom within each group.
Explanation:
The valence electrons are the outermost shell electrons.
Therefore, the number of valence electrons does not increase from top to bottom within each of the group.
Down a group, the number of valence electrons remains the same.
For group I elements, the number of electrons is 1.
The group is the vertical arrangement of elements.
From left to right across a period, the number of valence electrons increases because you move from group to group.
