Students will be able to identify and discuss their own career aspirations or relevant skills and knowledge and how they impact on others.
Burns in air to form carbon dioxide and water Example: Ethene burns in air. Alkenes react with hydrogen to form alkanes, called hydrogenation. Must use nickel as catalyst and heat. Phosphoric acid H3PO4high temperature of oC and atm pressure are needed as catalyst.
Addition of water Alkene reacts with water, in the form of steam, to produce alcohol.
Reddish-brown colour of bromine disappears. This shows that the compound is an alkene. Therefore, margarine is solid at room temperature. The Cracking of Alkanes Alkanes can be cracked into shorter chain hydrocarbons because of the higher value it has that it can create more variety of products in petrochemical industries.
The total number of carbon and hydrogen atoms from products should equal to the total number of carbon and hydrogen atoms in cracked alkane.
Octane can be cracked into simpler hydrocarbons such as the reaction below. Suggest the possible identity of product x. Due to different chain length, they have different physical properties e. Isomerism can occur in both alkanes and alkenes.
For alkene, double bond position can be changed. Fermentation of sugars with yeast 2. Reacting ethene with steam 1.
Fermenting glucose Fermentation is breakdown of sugars into smaller molecules by microorganisms. Oxygen is removed by limewater and carbon dioxide is produced during fermentation.
Alcohol is separated from solution by fractional distillation. Reacting Ethene with Steam Ethene and steam are passed over phosphoric acid H3PO4 as a catalyst under high temperature of oC and pressure of 65 atm.
The ethanol is separated by fractional distillation.CHAPTER 4: ANSWERS TO ASSIGNED PROBLEMS If so, write a balanced chemical equation for the reaction.
(a) Na 2CO 3 and AgNO 3 PPT. Na 2CO Use the Activity Series (Table ) to predict the outcome (if any) of each of the following reactions: ANY METAL ON LIST CAN BE OXIDIZED BY THE IONS OF AN ELEMENT. Many of you have probably heard of the ‘alkaline diet’. There are a few different versions of the acid-alkaline theory circulating the internet, but the basic claim is that the foods we eat leave behind an ‘ash’ after they are metabolized, and this ash can be acid or alkaline (alkaline meaning more basic on the pH scale).
According to the theory, it is in our best interest to make sure. Using the solubility rules, predict the products, balance the equation, and write the complete ionic and net ionic equations for each of the following reactions.
