Answer:
A)
1. Reaction will shift rightwards towards the products.
2. It will turn green.
3. The solution will be cooler..
B) It will turn green.
Explanation:
Hello,
In this case, for the stated equilibrium:
![heat + Cu(H_2O)_6 ^{+2} (blue) + 4Br^- \rightleftharpoons 6H_2O + CuBr_4^{-2} (green)](https://tex.z-dn.net/?f=heat%20%2B%20Cu%28H_2O%29_6%20%5E%7B%2B2%7D%20%28blue%29%20%2B%204Br%5E-%20%5Crightleftharpoons%206H_2O%20%2B%20CuBr_4%5E%7B-2%7D%20%28green%29)
In such a way, by thinking out the Le Chatelier's principle, we can answer to each question:
A)
1. If potassium bromide, which adds bromide ions, is added more reactant is being added to the solution, therefore, the reaction will shift rightwards towards the products.
2. The formation of the green complex is favored, therefore, it will turn green.
3. The solution will be cooler as heat is converted into "cold" in order to reestablish equilibrium.
B) In this case, as the heat is a reactant, if more heat is added, more products will be formed, which implies that it will turn green.

Answer:
Coefficient of ![C_3H_8O_2=3](https://tex.z-dn.net/?f=C_3H_8O_2%3D3)
Coefficient of
=8
Explanation:
We are given that a reaction in which
reacts with ![KMnO_4](https://tex.z-dn.net/?f=KMnO_4)
We have to find the coefficient of each reactants in balanced reaction
![3C_3H_8O_2(aq)+8KMnO_4(aq)\rightarrow 3C_3H_2O_4K_2(aq)+8MnO_2(aq)+2KOH+8H_2O](https://tex.z-dn.net/?f=3C_3H_8O_2%28aq%29%2B8KMnO_4%28aq%29%5Crightarrow%203C_3H_2O_4K_2%28aq%29%2B8MnO_2%28aq%29%2B2KOH%2B8H_2O)
Coefficient is defined the constant value multiplied with a reactant in a reaction.
Coefficient of
=3
Coefficient of ![KMnO_4=8](https://tex.z-dn.net/?f=KMnO_4%3D8)
Coefficient of ![C_3H_2O_4K_2=3](https://tex.z-dn.net/?f=C_3H_2O_4K_2%3D3)
Coefficient of ![MnO_2=8](https://tex.z-dn.net/?f=MnO_2%3D8)
Coefficient of ![H_2O=8](https://tex.z-dn.net/?f=H_2O%3D8)
Coefficient of KOH=2
Hence, Coefficient of
and coefficient of ![KMnO_4=8](https://tex.z-dn.net/?f=KMnO_4%3D8)
Answer:
Transition Element
Explanation:
Transition elements are defined as those elements which can form at least one stable ion and has partially filled d-orbitals. They are also characterized by forming complex compounds and having different oxidation states for a single metal element.
Transition metals are present between the metals and the non metals in the periodic table occupying groups from 3 to 12. There general electronic configuration is as follow,
(n-1)d
¹⁻¹⁰ns
¹⁻²
The general configuration shows that for a given metal, the d sublevel will be in lower energy level as compared to corresponding s sublevel. For example,
Scandium is present in fourth period hence, its s sublevel is present in 4rth energy level so its d sublevel will be present in 3rd energy level respectively.
Hence, we can conclude that for transition metals the electron are present in highest occupied s sublevel and a nearby d sublevel
