D for sure the are baccsilly grems
Explanation:
Answer:
B. Optical
Explanation:
First, let's go through what isomerism is. Isomerism is the relation of two or more compounds, radicals, or ions that are composed of the same kinds and numbers of atoms but differ from each other in structural arrangement (structural isomerism), as CH3OCH3 and CH3CH2OH, or in the arrangement of their atoms in space and therefore in one or more properties. There are 5 types of structural isomerism. They are chain isomerism, position isomerism, functional group isomerism, metamerism, and tautomerism. This would mean that these types of structural isomerism that are in the options would be eliminated as the question ask which of the "following" is not a type of structural isomerism. This would leave the only option available which is Option B. Optical Isomerism. So instead of being a structural isomerism, it is a type of stereoisomerism. Stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in space is different in each isomer.
Therefore, the answer is Option B. Optical.
Answer:
Amount of Listerine can be prepared = 16.73 (Approx)
Explanation:
Given:
Listerine formula contains = 26.9% alcohol
Amount of alcohol = 4.5 L
Find:
Amount of Listerine can be prepared
Computation:
Amount of Listerine can be prepared = (Amount of alcohol) / (Listerine formula contains)
Amount of Listerine can be prepared = 4.5 / 26.9%
Amount of Listerine can be prepared = 16.73 (Approx)
The mass in grams of the given beryllium sulfide is 99.2 g. The correct option is the second option - 99.2 g BeS
<h3>Calculating mass of a compound </h3>
From the question, we are to determine the mass of the given beryllium sulfide.
From the given information,
Number of moles of beryllium sulfide (BeS) given = 2.42 moles
Using the formula,
Mass = Number of moles × Molar mass
Molar mass of BeS = 41 g/mol
Then,
Mass of BeS = 2.42 × 41
Mass of BeS = 99.22
Mass of BeS ≅ 99.2 g
Hence, the mass in grams of the given beryllium sulfide is 99.2 g. The correct option is the second option - 99.2 g BeS
