Answer:</h3>
Mole ratio of D to A is 1 : 4
<h3>
Explanation:</h3>
We are given the generic chemical equation;
4A + B → C + D
We are supposed to determine the mole ratio of D to A
What is mole ratio?
- Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
- We determine the mole ratio using the coefficients of reactants or products in question.
For example;
- In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.
- This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
- Thus, mole ratio of D to A is 1 : 4
The answer : A sublimation
Answer: ![[Ni(NH_3)_3Br]Cl](https://tex.z-dn.net/?f=%5BNi%28NH_3%29_3Br%5DCl)
and ![[Ni(NH_3)_3Cl]Br](https://tex.z-dn.net/?f=%5BNi%28NH_3%29_3Cl%5DBr)
are ionization isomers.
![[Pt(Cl)_2(SCN)_4]^{4-}](https://tex.z-dn.net/?f=%5BPt%28Cl%29_2%28SCN%29_4%5D%5E%7B4-%7D)
and ![[Pt(Cl)_2(NCS)_4]^{4-}](https://tex.z-dn.net/?f=%5BPt%28Cl%29_2%28NCS%29_4%5D%5E%7B4-%7D)
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 and 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 and are linkage isomers.
