A skeletal structure for bromate (BrO3-) and would need a drawing of how to draw the lewis structure that follows the octet rule on all atoms.​

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

H tricky one let me think and get back to u

Reducing agents  oxidized by the reaction 

#2- the hno3 has a h+ ion and the naoh has an oh- ion
