Chemical formula

Where: i : Number of components Xi : Mole fraction for component ( i ) Cn: The total number of carbon atoms Cni : Number of carbon atoms for component ( i ) H_m = ∑ X_i H_mi (3.3) Where: Hm: The total number of hydrogen atoms Hmi : Number of hydrogen atoms for component ( i ) CnHm : The average chemical formula So the average chemical formula has been determined as in the above equations according to the percentages of each components for Iraqi light naphtha which have been set in the table (3.3), [33], and it is found C5.774H12.85 . The LPG fuel made up of several different gases, so it’s chemical formula can be determined in a similar way as naphtha, by using…

: The chemical formula of a compound will be determined using the mass of each individual element that is present in a weighed sample of that compound. The chemical formula shows the proportions of elements in a specific compound. This proportion is uniform to all samples of the same compound. Using the mass of each element, the moles of the element in the compound can be found and then compared to that of the other elements. This will create our atom ratio which will lead to our mole ratio. The…

The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. The water of hydration of the copper chloride hydrate sample will be determined as well as the mass of copper and chlorine through a chemical reaction. The results will be used to calculate the moles of copper and chlorine and then the empirical formula of the compound. Techniques used: In this experiment, different…

Determining the Chemical Formula of a Hydrate PROCEDURE Experiment required: copper (II) sulfate hydrate, 2 crucibles, electronic mass balance, bunsen burner, iron ring, crucible tong, clay triangle, wire gauze, retort stand, 1. Individuals should wear goggles on and tied hair back before the experiment started. 2. The mass of an empty crucible cover was measured. 3. Approximately 2.00g of copper (II) sulfate hydrate samples was taken out and put into the crucible. 4. The mass of the crucible…

ACTIVITY TWO: EVALUATION Spreadsheet model: I created my spreadsheet model by first following the “design for a basic model” this helped me to create three sheets called “Expenditure, Income and Summary”. Within these three sheets I created tables and colour coded them: The tables coloured yellow: require data input. The tables coloured blue: require calculations using formula or function. The table coloured red: require calculations using formula or function and could also require that their…

Children younger than ten months old have immature gastrointestinal systems and are unable to properly digest and absorb the nutrients found in cow’s milk. Many of the nutrients in baby formula are not natural or easy to absorb. It’s hard to mimic the right mixture of vitamins and minerals that the mother’s body knows to give her child, which is why breastmilk is always best. So, how would you make baby formula at home and have the proper nutrition for your child? Before we have a look…

finished. The convenience of breastfeeding is a giant plus because forgetting the bottle or formula at home will not be a problem. Many mothers do not feel comfortable about feeding their baby in public with no coverage which isn’t a problem because many companies are providing rooms attached to most women…

In 1998, Elizabeth Whitaker wrote “Ancient Bodies, Modern Customs, and Our Health”. This article focuses on how culture plays a role in our health, well-being and raising our children. When going about our everyday lives, no one ever thinks about how culture plays a big part in how we raise children and how we care for our bodies. When it comes to the health of our babies and breastfeeding, I believe that it is very important. There are so many chemicals going into everything that we eat…

Complementary foods are foods other than breast milk or infant formula (liquids, semisolids, and solids) introduced to an infant to provide nutrients. The ideal time to introduce complementary foods in the diets of infants is difficult to pinpoint. Complementary foods introduced too early are of little benefit to the infant and may even be harmful due to the possibility of choking, developing food allergies, or causing an infant to consume less than the appropriate amount of breast milk or…

mothers: whether to breast-feed or formula-feed their babies. Breast feeding dates back to eighteen hundred BC in Greek culture where wet nurses came about as women hired to feed another woman’s child. Formula feeding did not come to light until two hundred years after which then led to a “refined and hygienic” bottle in the industrial ages (Stevens). While both have advantages and disadvantages, breastfeeding has shown to be more beneficial for mother and child. Although some may argue the…
