The uncertainty reduction theory was created with intention of giving an explanation to an everyday occurrence when encountering new people. The theory gives reason to something everyday people experience regularly without consciously thinking about it. Psychology had attempted to explain the emotional process of first encounters but never like this. Although a lot of thought and consideration had been put into this‚ there was no way it could consistently cover every aspect it addresses. Diving further

Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3 Na2CO3 + CO2 + H2O 2NaHCO3 Na2O + 2CO2 + H2O Variables: Independent: Original

ABSTRACT OBJECTIVE To learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be

Title: Preparation and Standardization of a Sodium Hydroxide Solution Objective/Purpose: The objective of this experiment will be the standardization of sodium hydroxide using potassium hydrogen phthalate by the titration method. Introduction: The concentration of solutions can be reported in terms of molarity and normality. Molarity is equal to: HCL‚ HBR‚ H2SO4‚ HNO3 M = mol Solute (mol) (Monoprotic) (Diprotic) _______________ V(L)g solutions (L)

35 Discussion Background: Potassium permanaganate is widely used as an oxidizing agent in volumetric analysis. In acid solution‚ MnO4- ion undergoes reduction to Mn2+ this is the equation: 8H+(aq) + Mno4-(aq) + 5e- Mn2+(aq) + 4H2O Since the KMnO4 – ion is violet and the Mn2+ ion is nearly colorless‚ the end point titrations using KMnO4 as the titrant can be taken as the first pink color that appears in the solution (and stays without disappearing). The titration which involves the

Standardisation of a Solution of Sodium Hydroxide: Introduction: In a lot of cases it isn’t possible to prepare a solution by accurate weighing of the solute‚ dissolving in water and diluting to volume. There are many possible reasons for this‚ but in the case of sodium hydroxide‚ the solid absorbs moisture from the air‚ and also reacts with carbon dioxide from the air. In that case‚ it cannot be accurately weighed in air. In an experiment like this‚ a solution of the approximate required concentration

Spot reduction refers to the fallacy that fat can be targeted for reduction from a specific area of the body and that it can be achieved through exercise of specific muscles in the desired area‚ such as exercising the abdominal muscles in an effort to lose weight in or around one’s midsection. If anyone who said that you should do a certain exercise to burn the fats in a specific area‚ DO NOT take any more advise from that person. There have been many studies that shows spot reduction is not possible
