In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

Answer:
<h3>The answer is 2.16 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>2.16 moles</h3>

Explain in terms of particle behavior why smoke particles cause the detector alarm to sound
Smoke detectors are of many types but they rely on the principle of diffusion of smoke. Diffusion is the movement of particles from a region of high concentration to a region of lower concentration. Smoke particles move in what is known as Brownian motion.
