What happens in a nuclear reaction?
During nuclear fusion reaction, large amount of energy is released in the process.When two nuclei are combined to form a heavy nucleus, there occurs a mass defect. In other words, the mass of heavy nucleus turns out to be less than the some of masses of the two nuclei.This mass results in the release of large amount of energy according to the relation E = mc2 Other fusion reactions and energy release 1. 1H2 + 1H2 ----> 2H4 + 24MeV 2. 1H2 + 1H3 ----> 2He4 + 0n1 + 17.6 MeV 3. 1H2 + 1H2 ----> 2He3 + 0n1 + 3.27 MeV

12 l of ammonia were produced by the Haber process How many liters of hydrogen were used during the reaction?
All gasses: 12 L NH3 * [3H / 1NH3] * [1H2 / 2H] = 12*3/2 = 18 L H2
What is tritium's mass number?
It is the 3rd isotope of Hydrogen: 1H3 meaning the mass number is 3, and that's why it is called : tri-tium(1 proton and 2 neutrons = 3 mass units)The second isotope is called Deuterium 1H2
What do you use to balance the number of atoms on each side of reaction?
Generally just simple math and the fact that the product has to equal the reactant (except maybe in nuclear reactions) Ex _C6H12O6 + _O2 -> _CO2 + _H2O 1. Find the reactant molecule that is the only source of certain atoms in the products: - Glucose (only source of carbon and hydrogen) x O2 is not the only source of oxygen glucose has oxygen as well 2. Place a 1 in front of it 1C6H12O6 + _O2 -> _CO2 + _H2O Now 1 glucose means that there are 6 Carbons and 12 Hydrogens 6 Carbons means that there are 6 carbon dioxides, 6CO2 12 Hydrogens means that there are 6 waters (6*2=12) , 6H2O 1C6H12O6 + _O2 -> 6CO2 + 6H2O 6 CO2 and 6H2O = 18 Oxygens 6 Oxygens are already in glucse 12 Oxygen remaining --> 6O2 1C6H12O6 + 6O2 -> 6CO2 + 6H2O ---------------------------------------------------------------------------- Sometimes this method will give you fractions _N2 + _H2 -> _NH3 _N2 + 1H2 -> _NH3 1H2 (2 Hydrogens) --> (2/3) NH3 (2Hydrogens) Multiply both by the denominator 3H2 (6 Hydrogens) --> 2NH3 (6Hydrogens) 2NH3 --> 1N2 1N2 + 3H2 -> 2NH3
What is the IUPAC name for H3O?

When 16 grams of methane gas combine with 64 grams of oxygen and 44 grams of carbon dioxide plus water what mass of water is produced?
1 mol Hydrogen (H) masses 1 gram 1 mol Oxygen (O) masses 16 gram 2 H2 + O2 --> 2H2O Equiv is H2 + 1/2 O2 --> H2O that is 1 mol of water 2g +16g ----> 18g H2O This reaction is explosive and goes to completion under standard temperature and pressure, but for pedants, all reactions are dynamic equilibria so in a confined volume there will be the tiniest proportion of H2 and O2 remaining. So minutely less than 18g is the answer.
