Answer:
See explanation below
Explanation:
In this reaction we have the ethyl acetoacetate which is reacting with 2 eq of sodium etoxide. The sodium etoxide is a base and it usually behaves as a nucleophyle of many reactions. Therefore, it will atract all the acidics protons in a molecule.
In the case of the ethyl acetoacetate, the protons that are in the methylene group (CH3 - CO - CH2 - COOCH2CH3) are the more acidic protons, therefore the etoxide will substract these protons instead of the protons of the methyl groups. This is because those hydrogens (in the methylene group) are between two carbonile groups, which make them more available and acidic for any reaction. As we have 2 equivalents of etoxide, means that it will substract both of the hydrogen atoms there, and then, reacts with the Br - CH2CH2 - Br and form a product of an aldolic condensation.
The mechanism of this reaction to reach X is shown in the attached picture.
The examination of a microscopic slice of an object with a petrological microscope in order to determine the source of the material, is known as thin-section analysis.
<h3>
What is thin section analysis?</h3>
The microscopic analysis of the content and structure of sediments is known as micromorphology, often known as thin-section analysis. Concepts of plasmic fabric and morphological traits and structures, which date from the early 1960s, were initially established in soil science.
<h3>
What makes petrography significant?</h3>
An essential tool for the fluid inclusion study is petrography. The fundamental purpose of petrography is to classify the fluid phases, such as monophase, biphase, or multiphase, and to deduce the relative chronology of the entrapment of fluid inclusions to determine whether it is primary, secondary, or pseudosecondary.

Answer:
8.
Explanation:
Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.
If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.
16 - 8 = 8
Answer:
Bacteria are multiple-celled microscopic organisms. It's gross but Fungi is the most abundent form of life on Earth.
