What is an enthalpy change in physical chemistry? How is enthalpy used to predict whether a reaction is endothermic or exothermic? When a metal gains an electron the process is endothermic? Is electrolysis endothermic or exothermic? Is dissolving salt in water exothermic or endothermic?
Enthalpy Crucial for understanding endothermic and exothermic processes. An endothermic reaction has a positive enthalpy change, indicating heat absorption. 6 Energy Transfers between systems can occur as work or heat. Energy transfer in an engine occurs as heat is converted to mechanical work. 7 Enth...
the father of biochemistry in the year 1930. this field combines biology as well as chemistry to study the chemical structure of a living organism. the biochemists get into the investigation of the chemical reactions and combinations which are involved in various processes like reproduction, heredit...
electron affinity is defined as the amount of energy released when an electron is added to a neutral atom to form an anion. the electron affinity is the potential energy change of the atom when an electron is added to a neutral gaseous atom to form a negative ion. so the more negative ...
The formula for boron trichloride is BCl_3. How many grams of boron are present in 1.28 moles of boron trichloride? How many moles of chlorine are present in 2.14 grams of boron trichloride? What is the enthalpy change for the following reaction: With a platinum catalyst, ammonia burns in...
A reversible change is one carried out in such as way that, when undone, both the system and surroundings (that is, the world) remain unchanged. Reversible = impossible: so why bother ? It should go without saying, of course, that any process that proceeds in infinitissimal steps would ...
various procedures. They construct a procedure for each of the eight changes to be observed, have their procedures approved by the instructor, and then carry out the procedures. The data collected is used to develop a set of criteria for determining whether a given change is chemical or ...
