Diffraction:
Diffraction<span> describes how waves bend, or change direction, as they travel around the edges of obstacles. </span>Diffraction<span> occurs in water waves, </span>sound <span>waves, and light waves, but the amount of </span>diffraction <span>depends on the size of the obstacle or opening in relation to the wavelength of the wave.</span>
Answer:
energy
Explanation:
The First Law of Thermodynamics (Conservation) states that energy is conserved, it cannot be created nor destroyed.
Answer:
The correct answer is : It is a salt because it is formed by the reaction of an acid and a base.
Explanation:
Sodium chloride is formed from the neutralization reaction between a strong acid (hydrochloric acid) and a strong base (sodium hydroxide):
HCl + NaOH ---> NaCl + H20
By reacting strong acid and base, they neutralize each other resulting in a salt (NaCl) and water.
Corresponds to an exothermic reaction (heat is released).
