happy april fools day everyone
I think your answer is A not sure tho
Answer:
The correct option is: 2 shared pairs, 2 lone pairs
Explanation:
Water is an inorganic molecule that is composed of one central oxygen atom and two hydrogen atoms bonded by covalent bonds. The molecular formula of water is H₂O and the bond angle is 109.47°.
The <em>oxygen is sp³ hybridized</em> and there are<em> two bond (or shared) pairs and two lone pairs </em>of electrons in a water molecule. The<em> structure of H₂O is bent </em>due to the <u>repulsive forces between the lone pairs of electrons</u>.
<em>Due to these repulsive forces, the H-O-H bond angle decreases from 109.47°, which is the ideal bond angle to 104.45°.</em>
Answer:
Option (4)
Explanation:
The primitive atmosphere was comprised of lesser or no amount of oxygen. With the progressive time, primitive organisms appeared such as the primitive aquatic plants, algae, and cyanobacteria, that carried out the process of photosynthesis in the presence of sunlight, water, and CO₂, and in return produced the food and oxygen. This is how the rapid photosynthesis process led to the increasing amount of oxygen in the atmosphere that facilitates the growth and evolution of different life forms on earth.
Thus, the correct answer is option (4).
