![]() ![]() AnswerĪ process in which ∆H is positive and ∆S is negative is spontaneous.ĪnswerĮntropy is the measure of orderliness of a system. Many reactions which are non-spontaneous at low temperature, are made spontaneous at high temperatures having positive entropy. Manganese, Mn Activates certain enzymes for building bones, it is required for creating cartilage and collagen to support normal bone growth.Hope the information shed above regarding NCERT MCQ Questions for Class 11 Chemistry Chapter 6 Thermodynamics with Answers Pdf free download has been useful to an extent. Also contributes to the formation of melanin pigment that protects our bodies from the sun's ultraviolet rays. Fatimah Alsunni partġ2 Elements in our Bodies Copper, Cu Manganese, MnĬopper contributes many of the enzymes responsible for the formation of blood vessels, bones and nerves. Chromium, Cr Increases the effectiveness of insulin, to maintains the level of sugar in the body, especially in brain. Iron, Fe The hemoglobin in the blood of the most important materials for human life, It is also important element of the iron particles of this article is the one who earns the blood red color, and it's responsible for the transfer of oxygen from the lungs to the various tissues of the body and cells. You can have medicines have base to decrease the acidity.ġ1 Elements in our Bodies Now let’s have a glance at the presence of chemistry in every subject of our life. Why you use this? You can eat banana that has lots of Mg, which react with acid and reduce acidity. The is like the anti – acid, when you use it stops the burns (the acidity). As you know, The stomach has HCl in it to digest the food.įrom the neutralization equation we benefit that the base reduce the acidity. How you stop it? You have to get rid from the food that increase the stomach acidity. Drinking lots of orange, lemon, or pineapple juice. Why you feel your stomach burn? Eating spicy food. Why you feel your stomach burn? How you stop it? Why you use this? Albandary’s Alburik part ![]() ![]() Lots of people have burn in their stomach. Why antacids reduce acidity in the stomach?

Zahra's Albashrawi partĤ Bases and Acids Acids and bases interact with each other to produce salts and water Acids dissolved in the solution to the hydrogen ions H + positively charged and negatively charged ions Bases disintegrate in water to ions hydroxide (OH-) and cation. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground. The electrons in the clouds move to the ground. Thus, the ground becomes positively charged because of the buildup of positive charges at the ground's surface. The negative charges in the bottom reject the negative charges in the neutral atoms (atoms with the same number of positive and negative charges) in the ground or other structures directly under the cloud. From waking up in the morning to the time of sleeping, chemistry has an essential role in various industries, Such as medicines, synthetic fiber packing, lightweight auto parts, synthetic rubber, tires, medical devices, paints and coatings, adhesives and materials used in refrigeration, and others, chemistry used even in the food used by human everywhere and every time, chemistry is always with us.Įlectrons and protons Lightning cased by electrons and protons when charges separate within a cloud, making the bottom of the cloud more negatively charged than the top of the cloud. ![]() We must realize the importance of chemistry in our daily life.
