Copper has two isotopes, copper-63 and copper-65. It has an atomic mass of 63.546 amu. Determine the percentage of copper-63 isotope present. Hint: Let x represent the amount of copper-63 and let 1-x represent the amount of copper-65. Round your final answer to the nearest percent.

In an effort to address concerns about global warming, a power plant in portland,oregon is designed to take all of its exhaust gases from its boilers and recycle the co2 using the solvay process to make sodium hydrogen carbonate. the reaction is shown below. nh3(g) + h2o(l) + co2(g) + nacl(aq) → nahco3(aq) + nh4cl(aq) how many liters each of nh3 and co2 (both at stp) would be consumed to produce 3.00 kg of sodium bicarbonate? the volume of both nh3 and co2 would be

Why is nh3 classified as a polar molecule
