Name the compound or give molecular formula.
1. Pt(NO2)2 : ?
Is it Platinum (II) Nitrite
2. Manganese (II) bromide pentahydrate:?
Is it MnBr2 • 5H2O
Yes for both
@DrBob222 thank you so much for all of your chemistry help. I have been struggling in my AP chemistry class and I just wanted to let you know how much you mean to me. Thank you for everything you have done for the struggling students. Love you.
1. To determine the compound or molecular formula of Pt(NO2)2, we need to break it down and identify its components.
- The symbol Pt represents platinum.
- The (NO2)2 portion contains the nitrite ion, NO2.
The roman numeral 2 in parentheses, "(II)", indicates the oxidation state of platinum. Therefore, Pt(NO2)2 is indeed Platinum (II) Nitrite.
2. To determine the compound or molecular formula of Manganese (II) bromide pentahydrate, we need to break it down and identify its components.
- The symbol Mn represents manganese.
- The (II) indicates the oxidation state of manganese.
- The bromide portion, Br, represents bromine.
Additionally, the term "pentahydrate" indicates that there are five water molecules associated with the compound.
Putting it all together, Manganese (II) bromide pentahydrate can be represented by the formula MnBr2 • 5H2O, where MnBr2 represents the bromide compound, and 5H2O represents the five water molecules.
