Question

If a synthesis reaction takes place between rubidium and bromine, the chemical formula for the product is _____.

Answer 1

Answer:

c) RbBr.

Explanation:

Hello,

In this case, since rubidium is in group IA, one electron will be eligible to pair during a chemical reaction. In addition, as long as bromine is in group VIIA, when pairing with a metal, just one electron is eligible to pair as well. Now, based on the aforesaid facts, we infer that the undergoing chemical reaction will be:

$2Rb(s)+Br_2(g)-->2RbBr$

So the formed product is $RbBr$ which is rubidium bromide, that is the c) answer.

Best regards.
