0.235 grams of magnesium reacts with excess hydrochloric acid to make 309ml of hydrogen gas at 28°c and 615 mmhg. (the vapor pressure of water at
28 c is 28.3 mmhg). from the experimental data what is the molar mass(molar mass is the number of grams that are in 1 mol) of magnesium? (the
number of moles of mg that react are the same as the number of moles of
hydrogen gas that are produced.]

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

In medium-sized stars such as the sun, nuclear fusion almost always means the fusing of nuclei to form , but larger stars can produce elements as heavy as
