10.) The structural formula of a certain aldehyde (related to formaldehyde) is H3C-CH2-CHO. Draw a Lewis structure for this aldehyde and determine the number of bonds present. Note that a single or a double or a triple bond counts as one bond.
Write the number, not the word.
Using the bond energies provided, calculate the enthalpy of the reaction (∆Hrxn, in kJ) for the combustion of methanol shown below. CH3OH(l) +3/2 O2 (g) → CO2 (g) + 2 H2O(g)
1. Refer to the following Bond energy table and determine if more energy is released per gram of fuel by burning natural gas (CH4) or butane (C4H10). Then, draw the Lewis Structure of all molecules.
