Answer:
Nonetheless, scientific change is connected with many other key issues in philosophy of science and broader epistemology, such as realism, rationality and relativism. The present article does not attempt to address them all. Higher-order debates regarding the methods of historiography or the epistemology of science, or the disciplinary differences between History and Philosophy, while important and interesting, represent an iteration of reflection on top of scientific change itself, and so go beyond the article’s scope.
Explanation:
The structure of the alkyl bromides used in a malonic ester synthesis of ethyl 2-methyl-4-pentenoate.
Ethyl 2-methyl-4-pentenoate by Malonic ester synthesis.
The alkylation of diethyl malonate or a related ester of malonic acid at the carbon alpha (immediately next) to both carbonyl groups, followed by conversion to a substituted acetic acid, characterizes the chemical reaction known as the malonic ester synthesis.
As a result, it is evident from the structure of ethyl 2-methyl-4-pentenoate that ethyl and methyl bromides are the alkyl bromides employed.

Answer:
B
Explanation:
A is not the answer. Although the statement is accurate in regards to gases, it does not explain why liquids and gases can flow.
B is the answer. Solids are in fixed structures. When you apply heat or pressure, these structures are broken apart and allowed to move freely.
C is not the answer. This is inaccurate. Changing the phase of a substance does not change the size of the particle.
D is not the answer. The opposite of this statement is true. The attractive forces between particles in a solid allow the substance to hold its structure. When you apply heat or pressure, the attractive forces are overpowered and the structure is broken.
