It's diagram c
im in masteringchemistry too :P
Diagram C, or the diagram that has more Li ions (circles with the + sign in them) than the SO4 molecules (circles with the 2- sign in them).
two atom of lithium ,one atom of sulfur ,four atoms of oxygen
Yes. Is two Li+ and one SO4-2 ions which dissociate in aqueous solution.
Because you have 6.68 moles of Li2SO4 and 2.500 liters of water, the overall molarity of your solution is 2.67 M.
When lithium hydroxide pellets are added to a solution of sulfuric acid Lithium Sulfate and water are formed. The balanced equation is 2LiOH + H2SO4 ------> Li2SO4 + 2H2O
Li2SO4
lithium sulphate
Li2SO4
Lithium sulfate
+6
Lithium sulfate
The formula for lithium sulfate is Li2SO4.
