Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

ABSTRACT The study was designed to explore the comparative effectiveness of transmitter of knowledge model and inductive inquiry model on students’ academic achievement. The main objectives of the study were to expose each of the two experimental groups to the transmitter of knowledge model and inductive inquiry model respectively and to compare the effectiveness of these models in the teaching of Social Studies. The pretest posttest control group experimental design was chosen for the experiment

Free Higher Education We pay a price for everything we get or take in this world. Although ambitions are well worth having‚ they are not to be cheaply won. Every day is an opportunity to make your life the way you want it to be. Anything is possible when you work towards it one day at a time. Skip a day and you lose momentum. Try to do it all at once and you will burn out. Work steadily and consistently to make every day count and you will reach your goals. Soon‚ with consistent effort‚ those

among the related concepts as well as possess knowledge of how children learn early number concepts. Place value is the idea that each digit in a number represents a certain amount‚ depending on the position that it occupies. Recognizing that children can count out a set by ones‚ as a future educator it’s important to help them see that groupings of tens and leftovers is a way of counting that same quantity. Counting plays a role in constructing base-ten ideas about quantity. Each approach helps

should college education be free in america? Research Topic All three of the research topics that I chose are very important to me. However the one topic that really stands out in my mind is‚ “should college education be free in the United States?” One reason this topic stands out to me‚ I believe America spends too much money importing goods. Especially goods that require some form of technology such as cell phones and gaming systems. The list goes on. I feel that if we train Americans to

The acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration

try to shed some light on knowledge from Islamic perspective. Generally speaking‚ the Arabic word for knowledge is ’ilm‚ which‚ in most cases‚ indicates to Islamic knowledge or matters related to Sheree’ah (Islamic Law). Although‚ some of the Quranic verses in this article refer to Islamic knowledge‚ yet they are general in their meaning‚ and thus can be used to refer to learning in general. The importance of education is a none disputable matter. Education is the knowledge of putting one ’s potentials
