Which of these is a pair of coordination isomers (aka ionization isomers)?
vagabundo [1.1K]

Answer:  [Ni(NH_3)_3Br]Cl and [Ni(NH_3)_3Cl]Br are ionization isomers.

[Pt(Cl)_2(SCN)_4]^{4-} and [Pt(Cl)_2(NCS)_4]^{4-} are linkage isomers.

Explanation:

Ionization isomerism occur when a ligand that is bound to the metal center exchanges places with an anion or neutral molecule that was originally outside the coordination complex

Thus [Ni(NH_3)_3Br]Cl and [Ni(NH_3)_3Cl]Br are ionization isomers.

Linkage isomerism is the existence of coordination compounds that have the same composition differing with the connectivity of the metal to a ligand.

Thus [Pt(Cl)_2(SCN)_4]^{4-} and [Pt(Cl)_2(NCS)_4]^{4-} are linkage isomers.

9) After lab, all of Darrel’s friends looked at his data and laughed and laughed. They told him that he was 30.8% too low in the
zaharov [31]
If he was 30.8% too low, it means that he was at 69.2% of the boiling point needed. So 50o C is 69.2% of total.

In order to know what 100% is, you can divide the number by it's percentage and then multiply it by a hundred.

So: 50/30.8=1.623
1.623*100=162.3
So the correct boiling point of the liquid he was working with in the lab is 162.3 oC

If 6.4 miles of Fe react with excess O2, how many miles of Fe2O3 can be formed? 4 Fe + 3 O2 -&gt; 2 Fe2O3
Yuri [45]
I'm assuming that by "miles" you mean moles.

If O2 is the excess reactant, that means Fe is the limiting reactant. That means that the amount of product being formed depends on the amount of Fe reactant present. To calculate the moles of Fe2O3 formed, start with the given 6.4 moles of Fe and use the mole to mole ratio given by the reaction as shown below:

6.4 mol Fe x \frac{2 mol Fe2O3}{4 mol Fe} = 3.2 mol Fe2O3
