How many milliliters of 0.250 M Sulfuric acid are required to react with 8.20 g of Sodium Hydrogen Carbonate (Na=23.0, H=1.0 amu, C=13.0
amu, O=16.0 amu, S =32.0 amu)
H2SO4 + 2 NaHCO3 → Na2SO4 +2 H2O + CO2

Which metal exist in liquid state and can be cut with knife ?

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.

About 3% of the water on earth is freshest. only about 40% of that freshwater is available for human use. why is so much freshwater unavailable for human use?
