What is the sum(c5c18) in cell c19 in excel?
=SUM(C5:C18) will add the values in all the cells from C5 to C18 and put the total in C19 when the formula is placed there.
C18 hydrocarbon polar nonpolar?
C18 hydrocarbons are typically nonpolar because they are made up of carbon and hydrogen atoms, which have similar electronegativities, resulting in no significant difference in charge distribution. This lack of polarity makes C18 hydrocarbons hydrophobic and immiscible with water.

What is C8 and C18?
C8 and C18 refer to carbon chain lengths in fatty acids. C8 means the fatty acid has 8 carbon atoms in its chain, while C18 means the fatty acid has 18 carbon atoms in its chain. The number of carbon atoms in a fatty acid chain can affect its properties and functions in the body.
What is C18 H34 O3?
C18 H34 O3 is the chemical formula for stearic acid. It is a saturated fatty acid commonly found in animal and vegetable fats. Stearic acid is used in various industrial applications, such as in the production of cosmetics, candles, and soaps.
What is the common name of a fatty acid that has c18 2n3 structure?
The common name for a fatty acid with a c18 2n3 structure is alpha-linolenic acid. It is an essential omega-3 fatty acid that is important for proper brain function and reducing inflammation in the body.
Explain the rationale for using a reversed phase C18 column for the determination of caffeine?
A reversed phase C18 column is commonly used for the determination of caffeine due to its hydrophobic properties, which can efficiently separate caffeine from other compounds in the sample based on their differing affinities for the stationary phase. Caffeine, being relatively nonpolar, interacts strongly with the C18 column, allowing for good retention and separation. Additionally, C18 columns are compatible with common mobile phases used in high-performance liquid chromatography (HPLC), making them a popular choice for caffeine analysis.
What is C18 phase in hplc column?
Both C8 and C18 columns are considered as examples of reversed phase liquid chromatography (RP). The stationary phase here is seen as a thin film of non-polar liquid phase that has been designed to be chemically anchored to an inert material (Silica gel particles). The non-polar layer is chemically linked to the silica particles surface by reaction with the polar silanol groups on the stationary phase surface and so rendering them (less polar or non-polar), The difference between the two columns will be in the length of the carbon-chain attached to the silica surface. Acoordingly C8 hplc columns have packing material composed of silica particles attached to C8 carbon units while C18 will, of course, have packing materials coated with C18 hydrophobic units. Categorically both are reversed phase but C18 columns will definitely be more "hydrophobic rather than the C8 columns.
Can you use a C18 column for HPLC with fluorescence detector and methanol as the mobile phase?
Yes, you can use a C18 column and methanol as a mobile phase with fluorescence detector. Fluorescence detector is generally used as it can detect the presence of compounds at a very low concentration.
What are all the parameters that have impact on the polarity of C8 and C18 columns?
The key parameters that impact the polarity of C8 and C18 columns are the length of the alkyl chain attached to the silica surface, the mobile phase composition, the pH of the mobile phase, and the column temperature. These factors influence the retention and selectivity of compounds on the stationary phase.
What type of vehicle is the C18 CAT?
A C18 CAT is an engine for tractors, combines and harvesters. It is also suitable for Aircraft Ground Support and Airport Rescue Firefighting Vehicles. The engine can also be used for compressors, mobile earth movers and trenchers among several other kinds of engine powered vehicles and devices.
