Specimens viewed with a compound microscope must be thin to allow light to pass through them. This ensures that the light rays can illuminate and pass through the specimen, which is necessary for magnifying the image and producing a clear view under the microscope. Thicker specimens would scatter or block the light, resulting in a blurry or dark image.
This compound must be dissociated.
For a compound to be steam distillable, it must have a higher vapor pressure than water at the temperature of the steam distillation process. Additionally, the compound should be stable under the conditions of steam distillation, meaning it does not decompose or react with water vapor. Lastly, the compound should have limited solubility in water to allow for efficient separation from the distillate.
The ratio of different atoms in a compound important because the compound has to achieve an equilibrium in terms of electrical charge. The net total of charges of the atoms forming a compound must be zero.
An ion is always electrically charged.
The chemical formula of a chemical compound is established after a detailed chemical analysis.
Specimens viewed with a compound microscope need to be thin to allow light to pass through and be focused by the lenses. Staining with dyes increases contrast and visibility of certain structures within the specimen by highlighting specific parts of the sample. This helps to distinguish different components and makes them easier to observe under the microscope.
Specimens must be thin in order to be viewed under the microscope because light can only pass through a certain thickness of material. A thin specimen allows light to pass through and interact with the cells, allowing the microscope to produce a magnified image. Thicker specimens would prevent light from passing through and produce a blurry or unreadable image.
The specimen must be dead. Electron microscopes view specimens in a vacuum- no air.
Specimens need to be thin to allow light to pass through them and be able to observe details and structures at a cellular or subcellular level. Thicker specimens would block the light and hinder the ability to visualize the specimen clearly under a microscope. A thin specimen also helps to reduce scattering and distortion of the image.

This compound must be dissociated.
A compound that can be separated by electrolysis must be in the LIQUID state of matter.
carbon
Dead specimens must be used with transmission electron microscopes because living cells are easily damaged by the high-energy electron beam used to create the image. Dead specimens can be fixed and stained to preserve their structure for imaging without being affected by the electron beam. Additionally, dead specimens allow for more control over sample preparation and consistency in imaging.
The sum of oxidation numbers in a compound is zero for a neutral compound and equal to the charge of the ion for an ionic compound. This rule stems from the fact that the total charge of a compound must be zero for a neutral compound and must balance out for an ionic compound.
The oxidation numbers in a neutral compound must equal zero. This is because the overall charge of a neutral compound is zero, so the sum of the oxidation numbers must balance out to zero.
Specimens need to be thin to allow light to pass through and enable clear visualization under the microscope. Staining with dyes helps to highlight specific structures or components within the specimen, making them easier to observe and distinguish.
