180 degrees
if it is bent (meaning there is a lone pair of electrons on Se) it is 109.5 degrees
Answer:
When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.

Answer:
The most reasonable estimate for the O–S–O bond angle in hyposulfite = 106°
Explanation:
Hyposulphite (so₂²⁻) is polyatomic ion .
According to VSEPR model
Total elrctron pairs
V = Valence shell electrons of central element
X = No. of monovalent surrounding atoms
C = Cationic charge
A = Anionic charge
Total electron pairs
That is two bond pairs and two lone pairs

Half reaction N_2 H_4 (aq) → N_2 (g)Balancing atoms except O and H N_2 H_4 (aq) → N_2 (g)Balancing charge N_2 H_4 (aq)→N_2 (g)+4H^+ (aq)Balanced half reaction for oxidation of hydrazine to gaseous nitrogen is N_2 H_4 (aq)→N_2 (g)+4 H^+ (aq)+ 4e^-
