B) This is the equation for the reaction when octane burns in a petrol engine: 2CH2 + 250, 16CO, + 18H2O
(i) How many moles of carbon dioxide are produced by one mole of octane?
(ii) How many moles of oxygen are required to react completely with one mole of octane?

Agas in a balloon at constant pressure has a volume of 160 ml at -125*c. what is its volume at 29.0*c?

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
