Answer:
- <em>On the atomic level, energy and matter exhibit the characteristics of </em><u>both waves and particles.</u>
Explanation:
The dual behavior of subatomic particles as waves and particles is known as the wave - particle duality.
And this principle is the basis of the quantum theory.
Such principle is widely applied to the electrons; i.e., the electrons posses wave and particle propeties, which must be understodd as that some of their properties may be explained as if they were particles and others as if they were waves.
For example, from the particle point of view electrons have mass. You can find in internet that the mass of one electron is about 9.1093837015×10⁻³¹ kg or about 1/1836 times the mass of one proton.)
Since, the point of view of the wave characteristics, electrons have wavelength, Louis de Broglie deduced the equation that relates the wavelength and the mass, through this realtion:
- Wavelength (λ) = Planck’s constant (h) divided by the product of the mass (m) and the the speed (v) of the particle.
λ = h / mv

Answer:
mass of Zn = 77.0 g
Explanation:
In the sample you have the same moles of Zn and Ga.
The formula for moles is:
Where MM: Molar Mass or Atomic Mass for elements
AM(Ga) = 69.723 amu
AM(Zn) = 65.38 amu
moles of Ga = 
mass of Zn =
