Consider the water(h_2o) molecule. what is the central atom? enter its chemical symbol. how many lone pairs are around the central atom? what is the ideal angle between the oxygen-hydrogen bonds? compared to the ideal angle, you would expect the actual angle between the oxygen-hydrogen bonds to be

oxygen is the central atom in water,it has two lone pairs of electrons, the bond angle is 104.27° The ideal H-O-H bond angle ought to have been 109.28°

Explanation:

The presence of lone pairs causes slight distortion in the bond angles of molecules. This distortion increases with the number of lone pairs present. Water has two lone pairs hence a greater distortion compared to ammonia.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

explanation:

i think option no d is the correct answer
