When a sample containing the hydrogen carbonate ion, HCO3-, for this experiment sodium hydrogen carbonate, NaHCO3, is allowed to react with nitric acid, carbon dioxide gas, CO2 (g) and liquid water, H2O (l) is released. You will use the formation of bubbles of CO2 gas to indicate that the hydrogen carbonate ion is present. Create a balanced equation of this reaction

Transportation is the largest single source of air pollution in the united states. air pollution can harm the environment and human health. which technology could offer a solution to this problem? mufflers that reduce noise motors that run on electricity tires that improve gas mileage

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.
