What reactant for the reaction that is powered by the sun hitting photosynthesis ll?
First of all it's not photosynthesis II, its photosystem II. well basically, the hydrogen atom within the water molecule loses its electrons and the electrons basically travels through all the photosytems via electron transport chains, towards the NADP Reductase where NADP+ is attached with the electrons from the hydrogen atoms of the water molecule to form NADPH
Which molecule is split apart in photosynthesis II?
Water molecule
The intermolecular force occurring when a hydrogen atom of one molecule is attracted to two unshared electrons of another molecule?
Hydrogen bond
What biological process does the plant need water for?
Photosynthesis is the biological process plants use to extract hydrogen from water. One hydrogen molecule is consumed to energise the process whilst the other hydrogen molecule is stored in the form of carbohydrate. Oxygen is released as a byproduct.
What is polarity in a water molecule?
The oxygen and hydrogen in water are bonded by a covalent bond. This means that the two lone lone electrons of hydrogen are shared with oxygen. Oxygen has a tendency to "hoard" electrons. So when it bonds with the hydrogen the two shared electrons are closer to the oxygen than to the hydrogen. As a result one side of water(the one with the oxygen) becomes slightly negative due to the fact that the oxygen has the two electrons closer to it. The side of the hydrogen becomes slightly positive as a result. When two or more molecules of water are placed together the slightly negatively charged oxygen from one molecule attracts the slightly positively charged hydrogen from another molecule forming a weak hydrogen bond. this hydrogen bond is formed as a result of the polarity of water.
In photosynthesis redox reactions ultimately transfer electrons from where?
§Photosynthesis, like respiration, is a redox (oxidation-reduction) process -Water molecules are split apart by oxidation, which means that they lose electrons along with hydrogen ions (H+) -Then CO2 is reduced to sugar as electrons and hydrogen ions are added to it This means that the electrons are moved from a water molecule to a carbon dioxide molecule. H2O >> CO2

What happens to electrons in a hydrogen bond?
No, electrons are never shared or transferred in a hydrogen bond. A hydrogen bond is just an attraction between partially positive particles and partially negative particles.
How many unshardd pairs of electrons are in a molecule of hydrogen iodide?
There would be three unshared pairs of electrons in a molecule of hydrogen iodide.
What is chlorophyll and what is it's role in photosynthesis?
Chlorophyll is a molecule found in chloroplast. When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high energy electrons make photosynthesis work.
Why is hydrogen covalent?
The electrons are shared in the diatomic hydrogen molecule.
What is the first molecule to provide electrons for photosynthesis?
Water 
How many electrons does a water molecule have?
A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
Which molecule is split apart in photosynthesis II?
Water molecule
Does hydrogen experience a hydrogen bonding?
The hydrogen molecule, H2, consists of two hydrogen atoms joined by a covalent bond in which one pair of electrons is shared. The hydrogen molecule does not experience hydrogen bonding, as it is a nonpolar molecule.
What happens chemically when chlorophyll absorbs light energy?
When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high-energy electrons make photosynthesis work
