Question

Write the net ionic equation for the reaction that occurs, if any, when gold is placed in a solution of hydrobromic acid

Answer 1

Answer:

ionic salt MX2

Explanation:

Atoms from an element in group IIA are allowed to react with atoms from an element in group VIIA. What type of compound is likely to form

elements from IIA are alkali earth metals (M) and need to lose

2 e^1- to become stable as M^2+

elements from VIIA ar halogens (X) and need to gain 1 e^1-

to become stable so one M^2+ combines with 2 X^1- to make

an ionic salt MX2
