Cooper is the substance that can't be decomposed by a chemical chAnge. So 4)
Answer:
Study the bone structure of limbs.
Explanation:
Study the bone structure of limbs can be used to find out the relatedness and relationship among three species because the pattern of bones structure is similar but the structure is different from one another due to different environmental conditions. This study provides important and useful information whether the three species are closely related or not. If they have similar bone structure than we can say that there are more chances that they are closely related to each other.

Answer:
The Empirical Formula.
Explanation:
From the empirical formula and using the weight (in g) of a given substance, we can come up with the molecular formula which is the actual weight of a substance. Sometimes, we find that the empircal formula is the molecular formula.
Answer:
AgBr
Explanation:
The salt, AgBr has a very low solubility is pure water. However, it has a high solubility in 1 M NH3. The reason behind this higher solubility of AgBr in 1 M aqueous ammonia solution is the formation of a complex as shown below;
AgBr(s) + 2NH3(aq) ----> [Ag(NH3)2]^+(aq) + Br^-(aq)
The formation of this linear silver diammine complex accounts for the higher solubility of AgBr in 1 M aqueous ammonia solution.
