Why can water molecules store energy in more ways than neon atoms?

Water contains more atoms connected by chemical bonds.

Explanation:

Neon is a noble gas, it is monoatomic in nature, this implies that it has only one atom present.

If we compare neon with water, water has three atoms present, two hydrogen atoms and one oxygen atom. These atoms are linked by chemical bonds. Energy is stored in each of these chemical bonds.

Hence water stores more energy than neon because it is polyatomic and contains chemical bonds.

In addition to the fact that both hydrogen atoms are attached to an oxygen atom through a covalent bond and that it requires a large amount of energy to separate the water molecules, each water molecule can  potentially form 4 hydrogen bonds with each other  so many water molecules giving rise to a structure responsible for its physico-chemical properties.

Explanation:

Water is one of the simplest molecules but at the same time one of the most complex in Chemistry.

It is said that a water molecule can store a lot of energy in its structure due to the links it can form with each other or with other water molecules.

Each of the water molecules has two bonds that require hydrogen with oxygen, but in addition, the Van der Waals interactions between nearby molecules must be taken into account.

Which makes it more complex and requires more energy to separate the water molecules.

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
