2) Calculate the volume (in L) of CO2 produced from the combustion of 5.0L of CzHs in an excess of Oz Assume all gases are measured at STP.

Draw the lewis dot structure for each of the following polyatomic ions

Choose all the answers that apply. fluorine (f) has an atomic number of 9 and an atomic weight of 18.99. fluorine has a. 9 protons b. 10 neutrons c. 18 electrons d. an atomic mass of 19 e. at least one isotope

The molecular weight of carbon dioxide, co2, is 44.00 amu, and the molecular weight of nitrous dioxide, no2, is 46.01 amu, so no2 diffuses co2
