Answer:
b option
Explanation:
H2O has a tetrahedral arrangement of molecules or an angular geometry. This is mainly because the repulsion from the lone pair combination is more than bond-pair repulsion.
Answer:
9256.5 g/ml
Explanation:
Use the formula,
Density = mass/volume
;Where you need to calculate the volume change firstly,
Volume = 238.0 - 207.4
;Volume = 30.6 ml
; Hence for calculating density,
; Density = 302.5 × 30.6
; Density = 9256.5 g/ml
