Summary
If all of the 0.1699 moles of BaCl2 were to be used in the reaction it would require 2 x 0.1699 = 0.3398 moles of AgNO3 for the reaction to go to completion. There are only 0.24489 moles of AgNO3 available which is less than the required 0.3398 moles.
If all of the 0.24489…

A powder of calcium carbonate can be taken and added with hydrochloric acid. This leads to the evolving of gas bubbles. These gas bubbles can be tested by either by passing it through lime water which will give a white precipitate. Or a lighter splinter can be introduced into the test tube. This splinter will go off immediately because of the carbon dioxide ...Download file to see next pagesRead More

...CHEMISTRY QUESTIONS Presented Intramolecular forces operate within the molecules or fundamental units of a substance. This would include the attraction between positive and negative ions in a crystal of an ionic compound, the covalent bonds in a molecular substance as well as the covalent bonds linking atoms in a network structure, such as that of carbon (diamond).Metallic bonds are also classified as intramolecular forces (Frederick, 1979, P.63)Intermolecular forces operate between, rather than within, the molecules of a covalent substance. This would include the attractions exerted by one molecule of a molecular substance on another, such as the force of attraction between water molecules in ice ,the attractions between atoms... relative...

...x100 = 65.62%. 137x27 Question – 3 a. In 1870, Markonikov laid down a basic principle of chemistry that holds till today. The Markonikov Rule states that when a hydrogen halide (Hydrochloric acid, HCl being an example) reacts with an asymmetrically substituted alkene the hydrogen attaches itself to the carbon atom that has the larger number of its hydrogen atoms substituted. The halogen automatically attaches itself to the carbon atom having the least number of its hydrogens substituted. An example of such an addition reaction: Cl2HC=CH2Cl + HCl  Cl2H 2 C=CH2Cl2 Here the halide chlorine attached to the right hand side of the molecule that had fewer hydrogen atoms replaced. b. Enantiomers...

The measurement given on the mass seems not to be accurate because the minimum measure of mass according to the apparatus is 0.0001, therefore if the measure was exactly 11.439 g then this should have been written as 11.4390 g. b) Volume of the gold cube 5.7 – 5.1 = 0.6ml c) Density and mass find volume of gold cube Density = Mass/Volume Volume =...

...Chemistry Describe the configuration of an atom. An atom is composed of a nucleus. The atom also possesses atomic orbitals and energy levels which are made up of electrons. 2.) Explain the process of radioactive decay which takes place on (^14)(^6)C or what is known as carbon 14. A radio carbon such as carbon 14 will undergo a process of electron mission, therefore losing energy and moving ultimately to a place of chaos or entropy. The following formula will illustrate the radioactive beta decay which will act on carbon 14: ^14_6C------> ^14_7N+e 3). Utilize the S P D orbital system to describe Potassium. An orbital is essentially a theory of something rather than an actual something. This orbital is said to contain...

... Introduction to Chemistry: Analysis of Oxygen (O2) Introduction Oxygen is a chemical element that largely forms part of the atmospheric and is widely recognized with the sustenance of life and survival of organisms. It has a formula of O­2. As a chemical element, this substance has an atomic number of 8 and belongs to the chalcogen group on the periodic table; thus, making it build and possess certain significant characteristics for its operations such as being a highly reactive non-metallic element. Subsequently, oxygen is widely used as an oxidizing agent through its readiness to form compounds (in most cases oxides), with most of the atmospheric elements (Bauer, Birk & Pamela 145-149). Identification by mass sets this element... in...

...and meaning attached to them and so sounds give melody to language. The right intonation of sounds can convey a host of human feelings such as empathy, anger. Sounds can show confidence or certainty of our words. This course has helped me a appreciate the two fold meaning that sound can bring into one sentence through the use of word stress and sentence intonations to alter meaning. e. The importance of contrastive or comparative studies and the ability to construct exercises for learners of English as a second language. Constructing exercises for learners of English as a second language is now easier because of the emphasis I have learned that phonetics play on the meaning and the message sentences...
