Binary ionic compounds contain two elements: one metal and one nonmetal. are binary ionic compounds. Ternary ionic compounds contain three elements, at least one metal and one nonmetal.
The ammonia gas, having a lower molecular weight than the hydrogen chloride, will diffuse faster and travel a greater length of the tube. Consequently, the white ring of ammonium chloride will form much closer to hydrochloric acid end of the tube. Which in conclusion your answer will be D :)
Answer:
(C) Total internal reflection
Explanation:
Total internal reflection :
- It is the complete reflection of light in the medium ( medium may be glass ,water etc ) from the surrounding surface.
- Total internal reflection occur when angle of incidence is greater than the limiting angle ( limiting angle is also known as critical angle ).
- Light can be transmitted through long fiber optic due to total internal reflection
So the option (c) is the correct option
Al(oh)3 because that is how u balance
Answer:
The OH group
Explanation:
Benzhydrol contains OH hydroxyl group in its molecule while fluorene does not. At first glance, one would think that OH, which contributes to hydrogen bonding would causes melting point of benzhydrol to be higher than fluorene. <em>However, </em>the structure of benzhydrol, which is 2 benzene rings connected to center hydroxyl carbon (PhCOHPh), allows for each benzene rings in benzhydrol to rotate until both rings are perpendicular to minimize repulsive force. This prevents the molecule from stacking on each other due to its non flat shape, and thus, lowering its melting point in contrast to flat fluorene molecule.
