Answer:
A) covalent bond
Explanation:
Covalent bonding generally happens between nonmetals.
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
Explanation:
6 Atoms!
Mg = 1 atom.
O = 4 atoms.
A = 1 atom.
Given mass of tungsten, W = 415 g
Molar mass of tungsten, W = 183.85 g/mol
Calculating moles of tungsten from mass and molar mass:
