Working out the Formula of Magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Apparatus Googles

signalled the transformation of hunting and gathering to agriculture. The patterns of immigration slowed down and they remained in an area. Permanent housing was a necessity in settled societies. Sturdy homes from sun-hardened clay ensured that they need not depend on temporary living quarters.Agricultural knowledge was spread around the world. Sedentary societies expanded farm sizes and began animal domestication. However there were challenges in an agricultural society. Issues such as malnutrition

1.0 SITUATIONAL ANALYSIS The Tinplate Company of India Limited (TCIL) is one of the major tinplate manufacturing companies of India. It was started in 1922 and is jointly held by Burmah Shell‚ Shaw Wallace‚ Tata Steel and Tata Iron & Steel Company. TCIL used to import its major raw material‚ Tin Mill Black Plate (TMBP)‚ till 1997. However‚ like all major steel mills worldwide it attained self sufficiency in TMBP by setting up its own cold rolling facility. It clearly showed that TCIL has the technical

Why We Do What We Do My teaching philosophy is best described by using the following analogy. A building does not stand tall for years on end without a good foundation. Weather its building a house‚ an apartment‚ a church‚ or a skyscraper‚ the foundation is the most important element for the building to stand tall for years. If a child can start out with the right knowledge to live a physically active lifestyle they have more of a chance to continue to live while being physically active. Pouring

Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical formula mass.
