What is the h-c-h bond angle predicted by lewis for ch3+?

bond angle = 120 °

Explanation:

Lewis structure is used to represent the arrangement of the electrons around the atom in a molecule. The electrons are shown by dots and the bonding electrons are shown by line between the two atoms.

For ,

The number of valence electrons = = 6  

The skeleton structure of the compound is in which one C molecule act as a central atom and is bonded to the three H with one sigma bond each.

Number of valence electrons used in skeletal structure = 6

So,  

Remaining valence electrons = 0

The Lewis structure of the compound is shown below:

The geometry is trigonal planar which has an angle of 120 °.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

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.
