Explain Carbondioxide Concentration.

1. A reaction at 21.7 ˚C and 1.03 atm produces 18.0 L of CO2 (g). Determine the number of moles of CO2 (g) produced. 2. Determine the volume (mL) of C2H5OH (l) that was combusted to produce the volume of CO2 (g) collected above. The density of C2H5OH (l) is 0.789 g/mL

Balance the following equation. Be sure to place a number in front of each molecule. Use "1"s if needed. 3 Na2O + 1 CaO + 2 Ca3(PO4)2 Na3PO4 <-- 3

These two problems are connected and I don't know how to do these.

[Review Topics] Calcium oxide can be used to "scrub" carbon dioxide from air. CaO(s)+CO,(g) → CaCO3(8) What mass of CO2 could be absorbed by 0.950 g of CaO? Mass= I g CO2 What volume would this CO2 occupy at STP? Volume= L CO2 Submit Answer Retry Entire Group 9 more group attempts remaining [References]
