Hydrogen peroxide is a substance that contains two hydrogen atoms and two oxygen atoms. Hydrogen peroxide is a weak acid and does not react formally with base substances. Catalase is found in many foods like beef liver‚ carrots‚ wheat sprouts‚ and potatoes‚ and more. Catalase is released when a protein is coming into the stomach a protein catalase goes and transforms the protein into food for human’s internal cells. Bubbles in an experiment where a raw potato is put into hydrogen peroxide

Numerical Studies of Microcombustion in a Micro-channel There are a lot of methods that converts chemical energy to thermal energy like fuel cells. But combustion is the most important one to obtain thermal energy from various fuels including hydrogen‚ natural gas‚ fuel oils because of its more energy output. Microcombustion is a potential energy source for small devices like unmanned vehicles and micro satellites .It is to be carried out in a miniature device called Microcombustor which is

tension of water‚ which is due to the formation of hydrogen bonds between adjacent water molecules. b. The ability to serve as a buffer‚ absorbing protons given off by acetic acid. c. The ability to orient water molecules so that their polarities neutralize the ions formed when the acid dissociates. d. The ability to form hydrogen bonds with the carbonyl and the hydroxyl groups of acetic acid. 3. The pH of a solution is equal to: a. b. c. d. e. the hydrogen ion concentration H+ log [H+] -log[H+] ln[H+]

What is collagen? Collagen is a simple protein made up of amino-acids. Amino acids are built from carbon‚ oxygen and hydrogen. In fact collagen makes up approximately 30% of the protein within the body. As a structure Collagen is intensely strong and is a vital protein that is found all over the body: In tendons and ligaments. It plays an important role in the protection function of the skin in that it helps limit the absorption and spreading of pathogenic substances‚ environmental toxins‚ micro

ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions. In introductory chemistry‚ the reactivity series or activity series is an empirical series of metals‚ in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water‚ single

it shares hydrogen atoms. it gains or loses neutrons. 0 out of 5 The correct answer is: it gains or loses electrons. Question 7 of 20 The symbol 3CO2 represents one atom of oxygen and three atoms of carbon. three atoms of carbon and one molecule of oxygen. three molecules of carbon dioxide. one atom of carbon and three atoms of oxygen. 0 out of 5 The correct answer is: three molecules of carbon dioxide. Question 8 of 20 In water‚ hydrogen bonding occurs between the hydrogen and an oxygen

wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid in lactate acid‚ it interfere with electrical signals in muscles and nerves‚ slows energy reactions‚ and impairs muscle contraction. The burn up we feel in intense exercise is the cause of hydrogen ion. During this experiment(Muscle fatigue lab) it will be seen that after a while of squeezing a small

a cheap method to produce hydrogen. A method of industrial synthesis of hydrogen and oxygen through electrolysis was developed by Dmitry Lachinov in 1888. Electrolysis of water requires excess energy in the form of over potential to overcome barriers. Without the excess energy the electrolysis of water happens very slowly or not at all. Water has an electrical conductivity about one 1‚000‚000 of seawater. The Purpose of electrolysis is to separate water into Hydrogen and Oxygen gas. My hypothesis

there is a presence of salicylic acid or starch as a binder‚ left in the product‚ two reactions can be set up. Ferric chloride can be used to test the product for a presence of salicylic acid. If salicylic acid is present‚ a red-violet color will appear in the mixture. This is because the phenolic group on salicylic acid forms a colored iron complex when reacted with ferric chloride. Iodine can be used to test the product for a presence of starch; this can be indicated by the solution turning a deep
