Tab was Coca-Cola’s first attempt to develop a diet soft drink‚ using saccharin as a sugar substitute. Introduced in 1963‚ the product is still sold today‚ although its sales have dwindled since the introduction of Diet Coke. The Coca-Cola Company also produces a number of other soft drinks including Fanta (introduced circa

metal: Acids give hydrogen gas along with respective salt when they react with a metal. Example:- Hydrogen gas and zinc chloride are formed when hydrochloric acid reacts with zinc metal. Hydrogen gas and sodium chloride are formed when hydrochloric acid reacts with sodium metal. Hydrogen gas and iron chloride are formed when hydrochloric acid reacts with iron. Hydrogen gas and zinc sulphate are formed when zinc metal reacts with sulphuric acid Test for hydrogen gas: The gas

Sodium (Na) is one of the vital dietary minerals that the human machine‚ your body‚ requires to keep it working day to day. Without the existence of this humble element‚ our basic warm blooded physiology would be all but impossible. Sodium is a mineral electrolyte‚ which allows it to regulate fluid balance. Having a healthy amount of the mineral in your body allows the right balance to be struck between the water retained in your cells and the vital electrolytes held alongside it for other purposes

is an esterification process that is used to make so from the hydrolysis of fats and oils. This process have the glycerol molecule‚ and a sodium carboxylate salt in most case sodium stearate being formed‚ however this salt depends on the base being used. In the experiment 23ml of vegetable oil was mixed with 20ml of ethyl alcohol along with 20 ml of 25% sodium hydroxide in a 250-mL Erlenmeyer flask. The content was then heated on a water bath whilst gently mixing with a glass rod. After 20 minutes

mechanism‚ sodium ions are able to pull other substances along with them through a cell membrane. A carrier protein situated in the cell membrane serves as an attachment point for the co-transport of the sodium ion as well as the other substance. Once attached‚ both the sodium ion and the other substance are transported to the interior of the cell together. This is due to the diffusion energy gradient of the sodium ion. Examples of co-transport: Sodium-glucose co-transport mechanism The sodium ion and

The goal for this experiment is to determine which out of the four balanced chemical equations best represent the thermal decomposition of sodium bicarbonate. The guiding question will be answered with the outcome of the sodium bicarbonates thermal decomposition and it being plugged in into the four balanced chemical equations. John Dalton atomic theory explains two fundamental laws of chemistry which are the law of conservation of mass and the law of definite proportions. The atomic theory states

Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate
