C or A. I can’t decide tho. I know most def it’s gotta be one of them two.
I would say that oceans help regulate weather, gobal warming, and solar radiation, but also depends on the level of carbon dioxide in the atmosphere level. So basically the oceans absorbs heat radiation from the sun and it retains the heat, which then the atmosphere comes in and also helps retain the heat which then releases the heat after sunset into space, regulating weather around the globe, since most of the globe is also covered by oceans and water.
Answer :
(a)
In this Lewis dot structure, there are 3 bond pair and 0 lone pair on the central atom. The total number of electron pair is 3. So, the hybridization of the molecule will be, and the geometry will be, trigonal planar.
(b)
In this Lewis dot structure, there are 4 bond pair and 0 lone pair on the central atom. The total number of electron pair is 4. So, the hybridization of the molecule will be, and the geometry will be, tetrahedral.
(c)
In this Lewis dot structure, there are 3 bond pair and 1 lone pair on the central atom. The total number of electron pair is 4. So, the hybridization of the molecule will be, but the the fourth position will be occupied by one lone pair. Hence, the geometry will be, trigonal pyramidal not tetrahedral.
(d)
In this Lewis dot structure, there are 2 bond pair and 1 lone pair on the central atom. The total number of electron pair is 3. So, the hybridization of the molecule will be, but the the third position will be occupied by one lone pair. Hence, the geometry will be, bent not linear.
