Answer:
Ba^2+ (aq) +SO4^2- (aq) →BaSO4(s)
Explanation:
you really need to learn how to do this yourself - its really important throughout level chem, pre-ap chem, and especially if you plan on moving on to ap chem!!
She has 3 I just did that test. Have a good day
The reaction for magnesium iodide when put into water is as below
MgI2(s) → Mg^2+(aq) + 2I^-(aq)
when magnesium iodide but into water it dissociate/ ionize completely into Mg^2+ and 2l^- ions. Magnesium iodide dissociate/ionize completely because magnesium iodide is a strong electrolyte which dissociate/ ionize completely into their ions when it is put into water .
It is necessary to make a logical system for naming compounds because there are so many of them and thinking of arbitrary random names for each one and then later remembering them all would be impossible. Also, they need to be all recognized and standardized for global use so as to have everyone use the same system.
