100 moles of ethane (C2H6) are burned with 50% excess air. The percentage conversion of the ethane is 90%. Of the ethane burned, 25% reacts to form CO and the balance reacts to form CO2. Calculate the mole composition of the stack gas on a dry basis and the mole ratio of water to dry stack gas.

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
