Ca(s) + 2H2O(l) + Ca(OH)2(aq) + H2(9) When 40.1 grams of Ca(s) reacts completely
with the water, what is the total volume, at STP,
of II,(g) produced?
(1) 1.00 L
(3) 22,4 L
(2) 2.00 L
(4) 44.8 L

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

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

What is the main reason why some developing countries fear the increase the free trade policies around the world?
