a chemical reaction will occur spontaneously or non-spontaneously is an important aspect of thermodynamics. Spontaneity is determined from free energy‚ or Gibbs free energy. The equation (1) gives the relationship of how entropy (∆S) and enthalpy (∆H) along with temperature affects the amount of free energy‚ and henceforth the spontaneity. A spontaneous process may be quick or slow‚ and it is only affected by temperature and energy‚ therefore it is not related to kinetics or reaction rate. equation

People usually will marry within there ethnic group‚ nationality or social group. This is Endogamy also called in-marriage‚ custom enjoining one to marry within one’s own group.

Title: Studying SN1 and SN2 Reactions: Nucleophilic Substitutions at the saturated carbon Lab Partner: Jeszie Geronimo Objective and purpose: the purpose of this experiment is to convert a primary alcohol to an alkyl bromide using a Sn2 Reaction. Investigate some factors that influence the rate of Sn1 reactions. The second part of this lab will focus more on how unlike factors influence the rate of reactions in anSN1 reactions. The factors that we will be inspecting are the leaving groups‚ Cl-

Introduction In a Grignard reaction‚ a Grignard reagent (R–MgX) adds to the carbonyl group in an aldehyde or ketone to form an alcohol (Figure 1). The reaction of a Grignard reagent with formaldehyde can be to synthesize a primary alcohol‚ with any other aldehyde can be used to synthesize a secondary alcohol‚ while the reaction with ketone is useful in the synthesis of a tertiary alcohol. Figure 1. General reaction mechanism of a Grignard Reaction The preparation of the Grignard reagent involves

compare that relative reactivity of Na and k -Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water. Discuss the similarities and differences in the behavior of the metals tested with water relative to their positions

Naeem Davis‚ the homeless man who self-medicated his bipolar disorder with marijuana seemed‚ to have a problem with Ki-Suk Han at the time of the event. However‚ he was not the only one who was not being himself. Ki-Suk Han drank a few bottles and happened to be drunk at the time of the incident when he was killed. At the site of the murder‚ there were many eye witnesses who saw the murder of Ki-Suk Han‚ but in reality who was

The calculation for formula mass helps determine if you need to convert grams to a particular substance to moles‚ from a product. Moles are numbers that are in front of formulae. E.g.‚ 6NaCl‚ 6 is the equation for this formula. A mole would help you balance a skeleton equation‚ and also allows you to calculate how many moles are needed to take part in a chemical reaction.
