If it has a metal and a nonmetal bonded together it is an ionic bond. you are looking for non-metal non-metal bond. those are all covalent bonds. answer is B
Hey there,
That is because, chlorine is more reactive than Bromine.
**Important note: The lower you go in the periodic table of elements, the less reactive the elements become.
Hope this helps :))

We take activities of Solids and liquids equal 1. The reason is there concentrations not at all change amount of reactant at equilibrium in the reaction. Hence we don't consider concentrations of pure solids and liquids while writing equilibrium constant.
So for above reaction, equilibrium constant (K) = [Sn^2 +] ^3 x 1 / [Fe^3+]^2 x 1. Ping me if you have any doubts.
Answer:
Energy cannot be created or destroyed.
Explanation:
According to the law of conservation of energy, energy can neither be created nor it can be destroyed. Energy can only be transformed from one matter to another. The conservation of energy remains constant in an isolated system. The law is applicable in the system that does not exchange energy in the environment. Energy changes its form but remains constant.
