The type of bonding present in water (H2O) is hydrogen bonding.
Answer:
Got your back
Explanation:
If the ions derived from different atoms are isoelectronic species, then they all have same number of electrons in their electronic shells and will have got same electronic configuration but their nuclear charge will differ because of their difference in number of protons in the nucleus. With increase in number of protons in the nucleus the electrons are more attracted towards nucleus thereby causing the decrease in ionic radius. On this principle our problem will be solved
The given ions are
7N-3
→no. of proton
=7
and
no of electron
=10
8O-2
→
no. of proton
=8
and
no of electron
=10
9F-→
no. of proton=9
and no of electron=10
11Na→
no. of proton=11
and no of electron=10
12 Mg-3→
no. of proton=12 and
no of electron=10
Hence the increasing order of ionic radius is
12Mg-3<11Na+<9F-<8O-2<7N-3
To rmember ->For isoelectronic species lower the nuclear charge higher the radius
Many transition metal ions(e.g. in soluble salt solutions) give colored hydroxide precipitates when mixed with aqueous sodium hydroxide solution. However zinc ions give a white hydroxide precipitate. These reactions can be used to help identify transition metal ions in solution.

Answer:
( A ) Increases
Explanation:
More room, basically means more creatures. Like in a bedroom, you can only fit amount of people if its small the ocean is like that with depth.
Hopefully this makes sense???
