3. what happens if hydrogen reacts with chlorine in direct sunlight .
4. differentiate between oxidation and reduction.
5. what is hydrogenation of vegetable oils
Answers
1. The anode is the electrode where electricity moves into. The cathode is the electrode where electricity is given out or flows out of. The anode is usually the positive side. A cathode is a negative side.
2. The hydrogen gas does not change the dry blue litmus paper because the gas is unable to disassociate its ions when the paper is dry and the red litmus paper stays red in color because hydrogen gas is acidic in nature. If the blue litmus paper is moistened then it may change into red.
3. when hydrogen and chlorine reacts in direct sunlight ;- it forms HYDROGEN CHLORIDE OR HYDROCHLORIC ACID (HCl). >its a vigorous and explosive reaction.
4. Oxidation is a reaction that removes an electron from a substance, reduction is a reaction that adds electrons to a substance.
5. Oils (such as vegetable, olive, sunflower) are liquids at room temperature. In the food industry, hydrogen is added to oils (in a process called hydrogenation) to make them more solid, or 'spreadable'. ... The use of hydrogenated helps to prolong the shelf-life of the food and maintain flavour stability.
