I am having lots of trouble with these questions:
Classify each of the following reactions in as many ways as possible. (Select all that apply.)

a)2 Rb(s) + Br2(g) 2 RbBr(s)

you can select:
-acid-base
-double-displacement
-gas evolution
-oxidation-reduction
-precipitation
-single-displacement
-synthesis

i thought it was gas,oxidation and synthesis but that was wrong then i tried

gas and snythesis but that was wrong also

please help!
