great efffors and plenty of sacrifice. No pain‚ no gains is very true in case of education. Those who aspire to reach the top of the academic ladder must work very hard. Scholars are not born scholars but made with hard work and perseverance. What a student needs the most is concentration and perseverance. We must always imbibe into us the three D’s - Devotion‚ Dedication and Determination. These three D’s have help cricketers‚ painters‚ writers‚ actors‚ scholars‚ dramatists and world leaders. These

Heat of Neutralization: Lab Report In part A of this lab I determined the heat capacity of a calorimeter made out of two Styrofoam cups nesting together with a cardboard top containing a hole in the middle. First I placed 50 mL of water in the calorimeter‚ waited five minutes for the water to reach equilibrium‚ and used the computer’s temperature instrument to record the final temperature of the system. Next I heated 50 mL of water in a 250 mL beaker until the water reached 43.1 C (approximately

ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The main purpose for this experimental lab is to determine the atomic weight of magnesium‚ as well as an underlying purpose in determining the relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing
