Well I don't know for sure but it can be sound waves.
Answer:
The correct answer is 0.89 mol.
Explanation:
At STP (Standard Temperature and Pressure) conditions, 1 mol of an ideal gas occupies a volume of 22.4 L. If we assume STP conditions, we can consider a convertion factor of 1 mol/22.4 L to convert the volume of NO₂ from liters to moles:
20,00 L x 1 mol/22.4 L = 0.89 mol
So, at STP, we would have 0.89 mol of NO₂
Answer:
Yes
Explanation:
If Mg + 2HCI is Blanced then MgCI2 + H2 is also Blanced . So yes
A saturated solution is made by dissolving as much solute as possible in a solute. For example, add table sugar (solute) to a glass of water (solvent) until no more sugar will dissolve even with vigorous stirring. The undissolved sugar settles to the bottom of the glass.

Answer:
Energy level (n = 4), d subshell (l = 2)
Step-by-step explanation:
The number in 4d tells you the energy level of the subshell: n = 4.
The letter d gives you the secondary quantum number l.
Depending on its value, the letter gives you the shape of the orbital.
l = 0 corresponds to an s orbital (spherical)
l = 1 corresponds to a p orbital (dumb-bell shaped)
l = 2 corresponds to a d orbital (four four-leaf clovers + one that looks like a dumbbell with a doughnut around its middle)
