Hon placed aquatic plants in several test tubes that were filled with water. then, he placed half of the test tubes in a dark closet and the other half in a well-lit room. when he recorded his data, some of the plants had formed many small bubbles on the leaves, and some did not.

which describes what hon most likely observed and the reason for these results?
a. the plants in the dark formed bubbles because they released hydrogen gas.
b. the plants in the dark formed bubbles because they released water vapor.
c. the plants in the light formed bubbles because they released carbon dioxide gas.
d. the plants in the light formed bubbles because they released oxygen gas.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
