All of the following reactions can be described as displacement reactions except:____________.
Lady_Fox [76]

Answer:

b

Explanation:

The reaction that is not a displacement reaction from all the options is C_6H_6_{(l)} + Cl_{2(g)} --> C_6H_5Cl_{(l)} + HCl_{(g)}

In a displacement reaction, a part of one of the reactants is replaced by another reactant. In single displacement reactions, one of the reactants completely displaces and replaces part of another reactant. In double displacement reaction, cations and anions in the reactants switch partners to form products.

<em>Options a, c, d, and e involves the displacement of a part of one of the reactants by another reactant while option b does not.</em>

Correct option = b.

Which statement most completely defines a wave? *
Svetllana [295]

Answer:

A wave transfers energy through a medium or empty space without transporting matter.

Explanation:

  • A wave is a transmission of a disturbance from one point known as the source to another.
  • Waves may transfer energy through a material medium or a vacuum without transporting matter.
  • Waves that transfer energy from one point to another through a material medium are known as mechanical waves.
  • Electromagnetic waves, on the other hand, are those that do not require a material medium for transmission, the transfer of energy is through a vacuum.
  • Waves can also be either transverse or longitudinal waves based on the vibration of particles relative to the direction of wave motion.
