Mission to be Accomplished

      The United Nations Association of the United States of America is a not-for-profit membership organization dedicated to building understanding of and support for the deals and vital work of the United Nations. Its educational and humanitarian campaigns allow people to make a global impact at the local level.
   
      Our A.B.A.T delegates are being trained by 2 advisers Angela Dimassi and Bassel Zaazaa. We as advisers, are providing our delegates extra practice concerning the attended sessions in Global Classrooms LAU Model United Nations (GC LAU MUN).  And we promise everyone that our mission will be accomplished.

Here are some photos of what we have done lately:

CHEMISTRY LAB - GRADE 11 A - SOLUTION AND DILUTION

SOLUTION AND DILUTION
We prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution.

A dilution is a common laboratory technique used to obtain the desired concentration. A dilution will always reduce the concentration of the sample

 

CHEMISTRY EXPERIMENT (GRADE 12 LS) pH-Titration of Strong Acid with Strong Base.

In this experiment, a strong acid solution (HCl) will be titrated with a strong base solution(NaOH) . A titration curve is then used to determine the endpoint and find the concentration of the unknown acid solution.. A digital pH-meter will be used to follow the titration of hydrochloric acid, HCl(aq) with sodium hydroxide, NaOH(aq). HCl(aq) + NaOH(aq) NaCl(aq) + H2O
