Identify the substance oxidized and the substance reduced inZn + S = ZnS |
|
Answer» Guyz it is a type of half oxidation reduction reactionThis electron transfer is a redox reaction. ... In the example above, zinc metal is the reducing agent; it loses two electrons (is oxidized) and becomes Zn2+ ion. The reactant that gains electrons (is reduced) causes an oxidation and is called an oxidizing agent. Guys , are u sure? How ,guys plz tell me Nothing is oxidised or reduced Nither of substamce is oxidised nor any substance is reduced I think Zinc is getting oxidised.so it is oxidation. |

why respiration is called exothermic reaction? |
|
Answer» Ask to your teacher Aparna We know that exothermic reaction is that reaction in which heat is released and in respiration also heat is released along with water and carbondioxide so respiration is also called exothermic reaction To ritul rajput...In respiration there is no need of food only aor or gases are involved "During Respiration, Glucose molecules are converted to other molecules in a series of steps. They finally end up as Carbon dioxide and Water. The reaction is exothermic because the C=O and O=H bonds in the products are so much more stable than the bonds in the reactants. " Respiration is called exothermic reaction because energy is released while taking food. |

What is human digestive |
| Answer» The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat, our body has to break the food down into smaller molecules that it can process; it also has to excrete waste.Most of the digestive organs (like the stomach and intestines) are tube-like and contain the food as it makes its way through the body. The digestive system is essentially a long, twisting tube that runs from the mouth to the ****, plus a few other organs (like the liver and pancreas) that produce or store digestive chemicals.The Digestive Process:The start of the process - the mouth:The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).On the way to the stomach: the esophagus - After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we\'re upside-down.In the stomach - The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme.In the small intestine - After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.In the large intestine - After passing through the small intestine, food passes into the large intestine. In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food. Many microbes (bacteria like Bacteroides, Lactobacillus acidophilus, Escherichia coli, and Klebsiella) in the large intestine help in the digestion process. The first part of the large intestine is called the cecum (the appendix is connected to the cecum). Food then travels upward in the ascending colon. The food travels across the abdomen in the transverse colon, goes back down the other side of the body in the descending colon, and then through the sigmoid colon.The end of the process - Solid waste is then stored in the rectum until it is excreted via the ****. | |
