Singapore to Harbin(China)‚ Singapore is located near the equator (1˚N) and Harbin is located at higher latitudes of (45˚N). At 27.5˚C‚ Singapore has a higher mean annual temperature than Harbin (3.6˚C). Thus‚ latitude is an important factor in influencing the temperature of a place because it determines the amount of SWR received from the sun. P (Relationship between factor and temperature + Definition) * Distance from sea affects temp of a place as it affects amt of heat gained & lost by

requires the interaction of both customer and technicians‚ it is essential that they both cooperate in order to solve the problem as soon as possible. Furthermore‚ Non-Violent Communication is strictly essential in this type of career‚ if there is aggression‚ the problem will see less likely to be solved‚ by proper communication this only can be solved‚ electronics is a field in which technical issues are difficult to fix because you actually cannot see what is happening in most of the electronic devices

Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

The purpose of this experiment is to separate a solution of an acidic and organic compound and purify its respective acidic product through the techniques of an acid base extraction‚ recrystallization‚ and use of Melt Temp (melting point range). The reaction of an unknown acid (3-chlorobenzoic acid) with diethyl and sodium hydroxide was observed‚ and the solution naturally separated into an aqueous and organic solution. The mixture of acid and organic solution was created and then separated through
