Use average bond energies to calculate delta Hrxn for the combustion of ethanol?
-1250 kj/mol
Which bond is the strongest ionic or covalent?
The strength of any bond ionic or covalent is highly variable. Look at a table of Bond Dissociation Energies and compare the energies to see which is stronger.
What does bond energy depend upon?
CH3CH2OH= 5(414)+347+360+464 3O2= 3(498) 2CO2= 2(-1598) 3H2O= 3(-928) All in all: -1245=~1250
What do polar bonds use delta notation for?
A polar bond is bond between two atoms where the bond is shared, but unequal. A delta notation in a polar bond marks the atom that has the strong part of the bond.
What is delta in delta 9 THC?
Position of the molecule's double bond (from 9 to 10). In the molecule of delta-8-THC the double bond stretches from 8 to 9.
What is phi delta thetas code?
A brother in the bond
What is a A chemical bond that is not totally ionic or covalent?
it would be a polar covalent bond, where the inequal sharing of an electron between two atoms results in a delta+ and delta- charge
What bond holds hydrogen and oxygen molecules together?
The bond between Hydrogen and Oxygen is covalent because these elements are both non-metals. The is called polar covalent bond . oxygen is delta negative.hydrogen is delta positive
Why don't all bonds have the same strength?
Strength of Covalent Bond vs Ionic Bond Apparently, ... When I check bond energies, they seem to be in the same range. ... [all in the gas phase] ...

Would C-Br bond be polar?
yes carbon would be delta plus and the bromine would be delta negative
What is the prediction of the relative bond energies needed to break?
The bonding energy depends on differences between electronegativities.
