    Why in the periodic table there is a so-called main group, transition and transition in ?? And why group tansisi in its location outside ?

      At this time was born modern SPU which is the perfect H.Mendeleev compiled based on the increase of atomic number and similarity of the character. Horizontal line called Period is arranged based on the increase of atomic number, while the vertical lane is arranged based on the similarity of the nature. Modern SPU is composed of 7 periods and 16 classes , Each group is composed of 8 class A (main class) and 8 group B (transition group).

      To provide a basic foundation for teachers and students in achieving basic competencies and indicators, provides an overview of the short-term work reference, as compiled by using a systems approach, influencing the development of individual students, as designed carefully before learning, results in a nurturant effect

ACID RAIN Acid rain, also known as acid deposition, is caused by emissions ofsulfur dioxide   (SO2) and   nitrogen oxides   (NOx) from power plants, cars and factories. Natural sources like  volcanoes ,  forest fire   and lightning   strikes also add to the man-made pollution. SO2 and NOx become acids when they enter the atmosphere and react with water vapor. The resulting sulfuric and nitric acids can fall as wet or dry depositions. Wet deposition is precipitation: acid rain, snow, sleet or fog. Dry deposition falls as acidic particulates or gases Scientists express the acidity of acid rain using the   pH scale. The scale defines a solution's acidity, neutrality or alkalinity based on its concentration of hydrogen ions. Acids have a high concentration of hydrogen ions and a low pH. The scale ranges from zero to 14, with pure water at a neutral 7.0. Most water, however, is not exactly pure. Even clean, normal rain has a pH of about 5.6. This is because it reacts

Classification of Matter

Matter  can be identified by its characteristic inertial and gravitational mass and the space that it occupies. Matter is typically commonly found in three different states: solid, liquid   and gas Introduction A  substance  is a sample of matter whose physical and chemical properties are the same throughout the sample because the matter has a constant composition. It is common to see substances changing from one state of matter to another. To differentiate the  states of matter  at least at a particle level, we look at the behavior of the particles within the substance.  When substances change state, it is because the spacing between the particles of the substances is changing due to a gain or loss of energy . For example, we all have probably observed that water can exist in three forms with different characteristic ways of behaving: the solid state (ice), liquid state (water), and gaseous state (water vapor and steam). Due to water's pr

CHEMISTRY IN EVERYDAY LIFE

Everything is made of chemicals. Many of the changes we observe in the world around we see that caused by chemical reactions. Chemistry is very important because it helps us to know the composition, structure& changes of matter. All the matters are made up of chemistry. In our every day like various chemical are being used in various from, some of those are being used as food, some of those used clanging etc. Photosynthesis    Chlorophyll in plant leaves converts carbon dioxide and water into glucose and oxygen.  Plants apply a chemichal reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It's one of the most coomon everyday life reaction and also one of the most important since this is how plants produce food for themselves and animals and convert carbon dioxide into oxygen. 6 CO 2  + 6 H 2 O + light → C 6 H 12 O 6  + 6 O 2 Aerobic Cellular Respiration  Here is the overall equation for aerobic cellular resp
