INTRODUCTION In order to understand better English on both spoken and written‚ the most valuable gifts offered the pupils is pronunciation. However‚ as a teacher‚ sometimes it is a bit difficult in contributing this particular gift. It can be a challenge to the teachers when they face the problems such as the pupils’ pronunciation habits are not easy to change and it is also hard to understand and make a correction of the wrong pronunciation made by the pupils themselves.

which out of the four balanced chemical equations best represent the thermal decomposition of sodium bicarbonate. The guiding question will be answered with the outcome of the sodium bicarbonates thermal decomposition and it being plugged in into the four balanced chemical equations. John Dalton atomic theory explains two fundamental laws of chemistry which are the law of conservation of mass and the law of definite proportions. The atomic theory states that a chemical reaction is simply a rearrangement

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants
