3. Let each shake of the pennies or thumbtacks represent 1 year. What is the half-life, in years, for the pennies in experiment 1? What is the half-ife, in years, for the
thumbtacks in experiment 2?

In experiment 1 it starts with 200 pennies and after one half life, 95 stable pennies are taken out.

In experiment 2 it starts with 50 thumbtacks and after one half life 12 stable ones are taken out.

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
