Given what we know, we can confirm that hair gel is considered a noncrystalline solid due to Atoms in the hair gel having no particular order or pattern.
<h3>What is a noncrystalline solid?</h3>
- This is a solid whose atoms are amorphous.
- What this means is that the atoms lack a specific order like most solids.
- The most common example of this is glass.
Therefore, given the definition of a noncrystalline solid as a solid whose atoms lack a specified order, we can confirm that the second option which states that "Atoms in the hair gel having no particular order or pattern" is correct.

Answer:
1.44 g
Explanation:
The problem gives you the molarity and volume of the target solution, so right from the start you know that you can use that information to determine the number of moles of hydrochloric acid that it must contain.
So, molarity measures a solution's concentration in terms of how many moles of solute, which in your case is hydrochloric acid, you get per liter of solution.
A
0.158 M
hydrochloric acid solution contains
0.158
moles of hydrochloric acid for very liter of solution. Since you're dealing with
250 mL
, the equivalent of

Answer: " <span>1.8 * 10²⁴ molecules of O₂ " .
________________________________________</span>
3.0 moles O₂ * (6.02 * 10²³ molecules O₂ / 1 mol O₂) =
[ (3.0) *(6.02 * 10²³) ] molecules O₂
= 1.806 * 10²⁴ ; round to 2 significant figures.
= 1.8 * 10²⁴ molecules of O₂ .
