Chemistry focuses on the properties and reactivity of the chemical elements. An element is defined as a pure substance, in which the smallest representation is an atom, with every atom of a particular element containing the same number of protons in its nucleus. For example, the element of ...
What is mL in physical chemistry? How to convert liters of water to grams with a formula What is the value of 0.8 g/mL expressed in kg/L? How many moles of water are there in 100 grams of water? How to convert mg of water to mL with a formula ...
Metabolism refers to the set of chemical reactions that occur in living organisms in order to maintain life. These reactions can be divided into two main types: catabolism and anabolism. Catabolism is the process of breaking down complex molecules into simpler ones, releasing energy in the process...
Because now the reaction is betweenone moleofCHX4CHX4andtwo molesofOX2OX2it doesn't make sense to me to talk about enthalpy change per mole anymore. Could someone explain intuitively what the per mole now represents? enthalpy units Share ...
To answer these questions, we need to go on a little journey, one that touches gently on chemistry, physics, and electronics. What is gallium nitride? Gallium nitride (the chemical formula for this is GaN) is a crystal-like semiconductor material with special properties. GaN has been used...
Discover more than 1000 ready-made analytical chemistry applications What Are the Types of Titration? A titration of acids and bases assesses the point at which an acid and a base mixed into a solution are neutralized. As such, an appropriate pH indicator is added to the titration chamber. Th...
Maltodextrin can alter the texture somewhat, since it is often used as a thickener. However, maltodextrin usually has a very fine texture. I doubt that it is the maltodextrin that is causing the gritty texture in the peanut butter; possibly it has more to do with the preparation process used...
What are the prefixes in organic chemistry? Why are prefixes used in naming covalent compounds? What are ionic compounds called? What are the common compounds of roentgenium? What is a polyatomic molecule? What is the name for the compound below? What is the name of the compound? What is...
The ordinate is in units of volts and abscissa in minutes. The signals are recorded at a wavelength of 284 nm using a UV detector. Retention time of each peak is marked above the peak and in the tabulated data below the chromatogram details of the retention time, area (as digital units)...
