Answer:
- is reused and recycled
- can dissolve more substances than any other liquid
Explanation:
Earth water is reused and recycles in the form of the water cycle (hydrological cycle). In this cycle, water from the earth surface evaporates in the atmosphere, cool and condense into cloud or snow and fall to the earth surface.
As a universal solvent, water can dissolve more substances than any other liquid. The polar arrangement of oxygen and hydrogen atom in the water molecules makes it excellent salt.
On Earth, ~2.5% is a freshwater whereas 97.5% is salt water. The pH of water differs for surface and salt water, i.e. neutral to alkaline respectively. Water molecules attract to other water molecules better than the other substances. Therefore, other options are incorrect.
Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue reacts with water to produce pink colored complex.
In this complex, ion forms an octahedral complex with six ligands.
As is a weak field ligand therefore ion remains in low spin state.
Hence electronic configuration of ion in this octahedral geometry is with total three unpaired electrons.
the sun cooks the clouds the clouds pee on the earth and all the water falls to earth, pushing all the wind down that's why we have earthquakes

Answer:
The answer to your question is 3.65 g of HCl
Explanation:
Data
volume = 1 l
[HCl] = 0.1 M
moles of HCl = ?
Process
1.- Calculate the number of moles
Molarity = moles / volume
-Solve for moles
moles = Molarity x volume
-Substitution
moles = 0.1 x 1
-Result
moles = 0.1 moles
2.- Convert moles to grams
-Calculate the molar mass of HCl
HCl = 1 + 35.5 = 36.5 g
-Convert
36.5 g of HCl ------------------- 1 mol
x ------------------- 0.1 moles
x = (0.1 x 36.5) / 1
-Result
x = 3.65 g
-How to prepare the solution
Once I have weighed the mass of HCl, I place it in a volumetric flask and pour enough water till 1 l.
