Robin and Alex are discussing how water molecules form when hydrogen and oxygen atoms combine. Robin writes the following chemical equation to explain the formation of water. However, Alex has a different opinion and suggests that the chemical reaction can be better represented by using the equation below.

Why does Alex’s equation better represent the reaction?

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
