Particle accelerators (atom Smasher) in the world

Particle accelerators (atom Smasher) in the world Particle accelerators (atom Smasher) in the world, which is designed as a portal for the views of the new physics, have resulted in findings first of something unexpected: fragments of material that does not behave the same as antimatter (antimatter counterparts ) of these materials. The invention, certainly, can correct the laws of particle physics (particle physics) and helps explain why our universe is composed of mostly of matter and not antimatter (antimatter.) Scientists at the Large Hadron Collider, a particle accelerator, a circular 17-mile (27km ) underground (underground) near Geneva, Switzerland, has been crashing protons at high speed to create a burst of energy. It was created a lot of energy subatomic particles. Now researchers from the LHCb experiment belongs to the accelerator have reported that some particles of matter created in the machine appear to behave differently from their antimatter partner, which ...

THERMO [WISSEN READ]

THERMO A. Die Reaktion ist exotherm und endotherm 1. Die exotherme Reaktion In einer exothermen Reaktion auftritt, um die Wärmeübertragung des Systems auf die Umwelt oder auf die Reaktionswärme freigesetzt. In einer exothermen Reaktion H Preis = (-) Beispiel: C (s) + O2 (g)  CO2 (g) + 393,5 kJ; H = -393,5 kJ 2. endotherme Reaktion In einer endothermen Reaktion auftritt, um die Wärmeübertragung aus der Umgebung auf das System oder die Reaktionswärme erforderlich. In einer endothermen Reaktion H Preis = (+) Beispiel: CaCO3 (s)  CaO (s) + CO 2 (g) - 178,5 kJ; H = 178,5 kJ B. Änderungen der Enthalpie ntalpi = H = Reaktionswärme bei konstantem Druck = Qp Die Enthalpie Änderung ist die Änderung der Energie bei einem konstanten Druck chemischen Änderungsereignis begleitet. a. Brechen Sie die Bindung erfordert Energie (= endotherm) Beispiel: H2  2H - ein kJ; H = + AKJ b. Die Bindungsbildung geben Energie (= exotherme) Beispi...

COUNTS CHEMICAL

COUNTS CHEMICAL Count chemicals are ways of calculating oriented basic laws of chemistry. In this case will be given a variety of sample questions and their chemical count pembahasanya. Examples of questions: 1. What percentage levels of calcium (Ca) in the calcium carbonate? (Ar: C = 12; O = 16; Ca = 40) Answer: 1 mol CaCO, containing 1 mol Ca + 1 + 3 mol mol C O Mr CaCO3 = 40 + 12 + 48 = 100 So the level of calcium in CaCO3 = 40/100 x 100% = 40% 2. A total of 5.4 grams of aluminum metal (Ar = 27) was treated with excess dilute hydrochloric acid according to the reaction: 2 Al (s) + 6 HCl (aq) 2 AlCl 3 (aq) + 3 H2 (g) How many grams of aluminum chloride, and how many liters of hydrogen gas generated at standard conditions? Answer: From equation can be expressed 2 moles of Al x 2 mol AlCl3  3 mol H2 5.4 grams of Al = 5.4 / 27 = 0.2 mol So: AlCl3 formed = 0.2 x Mr AlCl3 = 0.2 x 133.5 = 26.7 grams H2 gas volume produced (0 ° C...

STOIKIOMETRI DALAM ILMU KIMIA

Gambar
STOIKIOMETRI adalah cabang ilmu kimia yang mempelajari hubungan kuantitatif dari komposisi zat-zat kimia dan reaksi-reaksinya. A.      HUKUM-HUKUM DASAR ILMU KIMIA 1. HUKUM KEKEKALAN MASSA = HUKUM LAVOISIER "Massa zat-zat sebelum dan sesudah reaksi adalah tetap". Contoh: hidrogen  + oksigen              hidrogen oksida    (4g)         (32g)                          (36g) 2. HUKUM PERBANDINGAN TETAP = HUKUM PROUST "Perbandingan massa unsur-unsur dalam tiap-tiap senyawa adalah tetap" Contoh: a. Pada senyawa NH3 : massa N : massa H = 1 Ar . N : 3 Ar . H = 1 (14)  : 3 (1) = 14 : 3 b. Pada senyawa SO3 : massa S : massa 0 = 1 Ar . S : 3 Ar . O = 1 (32) : 3 (16) = 32 : 48 = 2 : 3 Keuntungan dari hukum Pr...
