Question Description

There are 4 questions total. I understand what I was taught in class but for some reason the online homework is completely different. All 4 are in the word doc. They pertain to gas, acid, and precipitation reactions and writing our the equation.

Attached are the solutions. Please reply if you have any questions or if I can help with anything else.

(a) Start by predicting the products of the equation. A precipitation reaction almost always
occurs by double displacement, so swap the cation and anions.
Possible products: BaBr2 and Mn(NO3)2
Now we need to determine if either of those products would be a solid and precipitate. To
figure that out you need to use the solubility rules. If you don't have a copy of solubility rules,
they can be found here:

ules
Let's consider BaBr2 first. Look for any rule dealing with halides or alkaline earth metals.
Rule 3 from that page, deals with halides stating that they are generally soluble. There are
some exceptions, but Ba is not one of them. That means BaBr2 would be soluble.
Then, you need to determine if Mn(NO3)2 would be soluble or insoluble. Rule 2 deals with
nitrates, which are generally soluble.
Since both of the products are soluble in water, then neither product would precipitate.
NO PRECIPITATE
(b). nickel(II) iodide + sodium phosphate
Start by working out what the chemical formulas would be, then predict the products and
balance the equation
NiI2 + Na3PO4 ---> NaI + Ni3(PO4)2
3 NiI2 + 2 Na3PO4 ---> 6 NaI...

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
