Each species is a separate type of organism.
- A species is a group of creatures that share similar traits. The same species of organisms are capable of sexual reproduction as well as interbreeding and producing fertile offspring. It is a fundamental unit of taxonomy and classification.
- The system is divided into seven categories: Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. Kingdom is the most inclusive category.
- In a group, many types of an organism can be included even if they do not share the same traits. But species is a group of organisms that share similar traits.
- For example, human beings are species as they are all alike in physical features, way of reproduction, etc. But the animal is considered a group because it included a variety of living beings.
Therefore, Each species is not considered a group.

Answer:
Balancing chemical equation means making a number of atoms or molecules equal on both sides. In other words, this means that the number of atoms and molecules of each reacting element needs to be the same as the number of atoms and molecules of those elements in the product.
Our reaction is:
AlBr3 + K2SO4 -> KBr + Al2(SO4)3
and we need to balance it.
Since there are 3 molecules of SO4 in the product we need to put 3 before the reactant K2SO4. There are also 2 atoms of Al in the product, so we need to put 2 in front AlBr3. Now we have 6 atoms of K and Br on the left side, so we need to put 6 in front of KBr in the product.
So, our balanced equation will look like this:
2AlBr3 + 3K2SO4 -> 6KBr + Al2(SO4)3
The mass of copper deposited is 9.589 g .
Given ,
A volatile cell using Cu/Cu2+ and Sn/Sn2+ half cells is set up at standard conditions ,and each compartment has a volume of 345 ml .
current = 0.17 A
time = 48 hrs =48 (60) (60) =172800 sec
we know , I = Q/t
thus , Q ,charge= It = 0.17 (17280) =29376 C
Then ,atomic mass of copper is 63 g
And valency of Cu is 2.
Thus , the equivalent mass of copper is 63/2 = 31.5
We know , 96500 coulombs of electricity produce copper = 31.5 g
29376 C of electricity produce copper =9.589 g
Hence , 9.589 g of Copper is deposited .
