Passing an electric current through a sample of water (h2o) can cause the water to decompose into hydrogen gas (h2) and oxygen gas (o2) according to the following equation.. 2h2o= 2h2 + o2 . the molar mass of h2o is 18.01 g/mol. the molar mass of o2 is 32.00 g/mol. what mass of h2o, in grams, must react to produce 50.00 g of o2? . 14.07. 23.05. 28.14. 56.28

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
