Allright for H2O:
– The central atom is? –> the oxygen atom
– How many atoms are bonded to the central atom? –> 2 hydrogen atoms
– How many lone pairs of electrons are on the central atom? –> O has 6 electrons and has 2 single bonds, so 2 pairs
– How many single bonds are there in this molecule? –> 2
– How many multiple bonds (double and/or triple) are there in this molecule? –> none
For each of your molecules, answer the following questions:
1. Determine the electronegativity between the atoms of each molecule.
Electronegativity O = 3.44
Electronegativity H = 2.20
3.44-2.20=1.24, so the electronegativity between O and H = 1.24
2. Identify the bond as either ionic or covalent.
Electronegativity of 0.0-1.7 = covalent
Electronegativity of 1.7-3.3 = ionic
So it’s a covalent bond
3. State whether the molecule is polar or non polar.
Electronegativity of 0.5-1.7= polar covalent
4. Identify the structure as having hydrogen bonding, dipole-dipole moments or London dispersion forces (LDF).
H2O = hydrogen bonding
I am pretty sure that If I were asked to compare matter in solid, liquid, and gaseous states, the statement which would best defined a gas is highest energy, highest molecular motion, and least dense packaging of molecules. I choose this one because it’s not sensible to heat CO2 (in case of safety) and in the last option the amount of energy is not satisfying.
Hope it helps!

Use an arbitrary mass, 100 g is an easy number to work with.
60% of 100 g is 60 g, there are two A’s. Each A is 30 g
40 g is B, and there is only one, so B is 40 g.
AB2, would have a mass of 30 g + 2*40 g = 110 g
The new percent by mass composition of A is: 30g110g∗100%=27.3%
The new percent by mass composition of B is: 80g110g∗100%=72.7%

Identify two places in the krebs cycle where a decrease in free energy is coupled with an increase
Cellular respiration is the process of breaking down
food such as glucose into carbon dioxide and oxygen. During the process,
cellular respiration also releases energy in the form of ATP (adenosine
triphosphate) for use by all energy consuming activities of the cell. It is
found in the simultaneous process of Gycolysis and Kreb’s cycle. Glycolysis is
the breakdown of glucose to two pyruvic acids. These two pyruvic acids will be
used for the production of carbon dioxide and water in Kreb’s cycle.
