Pneumonia is an infection of the lungs. People with pneumonia usually complain of coughing, mucus production, fever, shortness of breath, and/or chest pain. 1  The body's immune system usually keeps bacteria from infecting the lungs.2  In bacterial pneumonia, bacteria reproduce in the lungs, while the body tries to fight off the infection. Inflammation is the body's attempt to destroy infection, and causes many of the other symptoms of bacterial pneumonia, including fever and chest pain. 2  Pneumonia can be very serious, because it directly interferes with the body's ability to exchange carbon dioxide and oxygen.
Homogeneous mixtures have uniform composition and properties throughout and are known as solutions. For e.g, when sugar/salt is dissolved in water it forms a solution in which â¦ the sugar/salt and water are uniformly mixed (the sugar is dissolved uniformly in water).
Homogeneous solution can be defined as that mixture which is formed by the combination of a solute in solvent, which cannot be seen as separate entities either by naked eye or through microscope or ultra microscope. A homogeneous solution cannot be separated by physical separation, simple filtration or even by ultra filtration. Homogeneous Mixture Examples Air around us is the most common example of homogeneous mixture. Air is composed of many individual elements like oxygen, nitrogen, hydrogen, ozone and noble gases, compound gases like carbon di oxide, nitrogen oxides, oxides of sulfur and water vapor.
