 Articel :     Photosynthesis: A new source of electrical energy? Biofuel cell works in cactus            chemical energy generated by photosynthesis into electrical energy by developing a novel biofuel cell. The advance offers a new strategy to convert solar energy into electrical energy in an environmentally-friendly and renewable manner. In addition, the biofuel cell could have important medical applications. Biofuel cell inserted in a cactus and graph showing the course of electrical current as a function of illumination of the cactus (black: glucose, red: O 2 ).     Scientists in France have transformed the chemical energy generated by photosynthesis into electrical energy by developing a novel biofuel cell. The advance offers a new strategy to convert solar energy into electrical energy in an environmentally-friendly and renewable manner. In addition, the biofuel cell could have important medical applications.         Photosynthesis is the proces

Explosion : CAUSE AND EFFECT    " If you light a match in a room with hydrogen gas and oxygen gas, there will be an explosion and most of the hydrogen and oxygen will combine to create water molecules." Demi : hello mely, are you okay today? Melyca : yes, i am oke Demi :  Do you know the explosion that happened at the chemical plant yesterday? Melica : yes, i know . why ? Demi : What causes the explosion to occur? Melica : because they light a match in a room with hydrogen gas and oxygen gas.  So what do you think is the efect of that? Demi :  oh of course the explosion and than  most of the hydrogen and oxygen will combine to create water molecules. Melica : oke ,thanks demi.see you in class.bye .. Demi : bye . Reaction :    

GIVE  EVIDENCE: chemistry in daily lif e Defenition :      evidence  is evidence   which serves to either support or counter a   hypothesis  Such evidence is expected to be empirical   evidence  and interpretation in accordance with something    method . Standards for something evidence vary according to the field of inquiry, but the strength of something evidence is generally based on the results of statitical   analysis  and the strength of something   controls . In daily life : Chemistry is a big part of your everyday life. You find chemistry in daily life in the foods you eat, the air you breathe, cleaning chemicals, your emotions and literally every object you can see or touch. Here's a look at 10 examples of everyday chemistry. Some common chemistry may be obvious, but others might surprise you. 1. Elements in the Human Body Your body is made up of chemical compounds, which are combinations of elements. While you probably know your body is mostly

DOUBLE BUBBLE MAPS Define :   Double Bubble Map is a great way to organize your thoughts when you are comparing and contrasting two things. In the middle you put how the two objects are alike. On the sides you put how the objects are different.   We can compare and contrast a Books, People, Objects, Animals, Places,Music, Events, etc. Magnesium (Mg) Magnesium,   12 Mg Spectral lines of magnesium General properties Name,  symbol magnesium, Mg Pronunciation / m æ ɡ ˈ n iː z i ə m / mag- nee -zee-əm Appearance shiny grey solid Magnesium in the  periodic table Be ↑ Mg ↓ Ca sodium  ←  magnesium  →  aluminium Atomic number   ( Z ) 12 Group ,  block group 2 (alkaline earth metals) ,  s-block Period period 3 Element
