This is how you write an equivalent fraction:2/4=1/2
how do you write 2 billion?
You would write it like this 2,000,000 or 2*10^6.
You can write a ratio three ways. Ex: 2/9, 2 to 9 or 2:9
Either 0.002 or 2 X 10-3.
Ba2(SO4)2
At first dissolution reactionBa(OH)2(s) --> Ba2+(aq) + 2OH-(aq)Then precipitation reaction Ba2+(aq) + [SO4 2-](s) --> BaSO4(s)
Cu2+ + (SO4)2- + Ba2+ + 2Cl- = Cu2+ + 2Cl- + BaSO4 (s)
Mn(SO4)2
This is not an equation but the chemical symbol of the cation: Ba2+.
The chemical equation is:Ba+ + 2 Cl- + 2 Na+ + SO4- = BaSO4(s) + 2 Cl- + 2 Na+
Barium chloride solution: Ba2+ and Cl-. Potassium sulfate: K+ and (SO4)2-.
H2SO4 = H+2 and SO4 minus2.
The chemical equation is:2 Al3+ + 3 (SO4)2- + 6 H+ = 2 Al3+ + 3 (SO4)2- + 3 H2(g)
Gold (III) Sulfate is an extremely unstable compound with the molecular formula Au2(SO4)3 and ionic formula Au3+2 (SO4)2-3.
SO4 is not a molecule. (SO4)2- is the sulfate ion.
It is SO4 -2 named as sulphate ion.
