Nickel Ii Sulfate Tetrahydrate

Help find a chemical formula? 3

What is the chemical formula?

a) Nickel (II) Tetrahydrate column

B) Copper (II) nitrate penta hydrate

And explain if possible.

Ni 2+ SO4 then NiSO4.4H2O Tetra = 4

Cu2 + NO3 then Cu (NO3) 2.5H20 penta = 5

Copper (II) nitrate pentahydrate

Nickel Tetrahydrate II column

Nickel Ii Sulfate Tetrahydrate

To find the best answer, search Li2O on this site. As it is a common, values are generally neutral. Another way to understand: So O has a valence of 2, while Li has a valence of +1, so you need 2 Li to cancel 2 oxygen. Therefore, the simplest formula of the compound is Li2O. Help, for example

Vinegar: Dilute acetic acid = CH3COOH (soluble means more water) Copper: is a metal: Cu is a symbol of copper NaCl: sodium chloride, table salt Sugar: C6H12O6 is glucose, 2 sugars is propaneol: CH3 CH (OH) CH3 (OH - The group is combined with other carbons in the propane molecule just ... but it helps and it deserves 10 points from you! You are right! :)
a) Ni2SO4 * 4H2O
Nickel (II) has a positive charge of two and a sulfate ion has a negative charge of two, so the two elements are in balance. Tetrahydrate 4 is H2O because tetra means four.
b) Cu (NO3) 2 * 5H2O
Copper (II) has two positive charges (as the name implies) and a nitrate ion has a negative charge, so you need to balance copper (II) and nitrate with 2 nitrate atoms. Pentahydrate means five water molecules (as in pentagram etc.)
