Copper is used in wiring because its metallic bonding gives its a high degree of freedom and the material a high conductivity.

 Ductility

Explanation:  Copper is used in wiring because -

1. It is a metal which is a good conductor of heat and electricity due to the motion of the free electrons.

2. It has high ductility and malleability.

Ductility is the feature in which the metals can be stretched in to thin wires and Malleability is the feature n which the metals can be made into thin sheets.

3. These wires can withdraw a wide load of electric current.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
