An acid and a base
For example
Sodium Hydroxide+Hydrochloric acid———Sodium chloride +Water
Answer:
NBr3 has a trigonal pyramidal geometry where the nitrogen atom is bonded to three bromine atoms and has one lone pairs. The individual bonds are polar, as bromine is less electronegative than nitrogen. The overall compound is also polar, as the dipoles do not cancel.
Explanation:

Second element ends with -ide
Answer:
Chemical reactivity increases down a group and decreases from left to right of a period.
Explanation:
The higher the ionization energy is, the lower the reactivity is. Since the ionization energy is highest in the top right corner of the periodic table, we can assume that the most reactive elements are in the opposite bottom left corner. This is because the electrons that react are farther away from the nucleus thus experience less attraction to the nucleus (called nuclear shielding). Therefore their electrons are more easily removed than elements that don't ecperience nuclear shielding.
