Define the term peptization. What do the terms hydrophobic and hydrophilic mean? What does polarity mean? Explain in detail. Al2O3 is amphoteric. What does this mean? Define the term decant. Define the term secondary carbon. Trans-stilbene is a solid whereas cis-stilbene is a liquid. What...
What is capillary action and how does it relate to the strengths of adhesive and cohesive forces? Define the term hydrophobic. What makes olive oil so hydrophobic? What do the terms hydrophobic and hydrophilic mean? What is the hydrophobic effect? Please provide your answer in the context of ...
or hydrolate, and from memory I recall this word first entering into aromatherapy vocabulary during the mid 1980’s. In the USA during the early 1990’s the term hydrosol was borrowed (it is used in other industries) and was applied to mean the water remaining after distillation, either as...
The assessment of acrylamide intake from diet most often relies on data collected from a single time point in adult life through food frequency questionnaires, which does not accurately reflect lifetime exposure to acrylamide (Ferrari et al., 2013; Granath and Törnqvist, 2003; Timmermann et ...
have high thermal stability and resistance to abrasion. Depending on the application, the surface may behydrophobicor hydrophilic. Bothpolar and nonpolaradsorbents exist. The adsorbents come in many shapes, including rods, pellets, and molded shapes. There are three major classes of industrial ...
The exact composition of Oakley's unobtainium is unknown and likely considered a trade secret. However, we know that it's a type of rubber compound with hydrophilic properties designed to enhance comfort and grip. What is unobtainium in Avatar?
Wood–water interactions are central to wood science, technology, and engineering. In the early twentieth century, the term “fiber saturation po
What does no net movement at equilibrium mean in the context of diffusion? Why do you think the protocol does not say to dissolve compounds directly in 1 liter of water? Why do polar and charged molecules tend to be soluble (hydrophilic) in the water? Define the term diffusion. What is ...
Instead, hydrosoluble, ionised, and hydrophilic molecules are rarely formulated in transdermal dosage forms as the percutaneous absorption of those compounds is challenging and they have often been left aside. Some hypotheses may be framed to explain this phenomenon: However, both hypotheses can be ...
Giving examples, define molecular formulas as used in the study of molecules. What do the terms hydrophobic and hydrophilic mean? What do you understand by the term diffusion of gases? Explain the concept of formal charge. Do formal charges represent actual separation of charges?
