Based on the properties of ideal gases, the true statements are:
- They have a small mass.
- They have no volume.
- They have no intermolecular forces.
<h3>What is an ideal gas?</h3>
An ideal gas is a gas which is assumed to have ideal properties.
The properties of an ideal gas are as follows:
- they have negligible mass
- do not attract or repel one another due to negligible intermolecular forces
- take up no space (have no constant volume)
- they collide with one another and the walls of their container
Therefore, based on the properties of ideal gases, the true statements are:
- They have a small mass.
- They have no volume.
- They have no intermolecular forces.

A gardener can fix acidic soil by adding lime over time.
PH = -log[H+] therefore lower pHs contain more H+ ions, so Jack's soup contains more free H+. Since pH is a logarithmic scale and Jack's soup has a pH of 2 less than Charlie's, it contains 10^2 = 100 times more H+ ions.
They are carbohydrates!!
If you could help me out by marking this as brainliest I would really appreciate it!! I'm trying to level up
Answer:
The required volume of hexane is 0.66245 Liters.
Explanation:
Volume of octane = v=1.0 L=
Density of octane= d =
Mass of octane ,m=
Moles of octane =
Mole percentage of Hexane = 45%
Mole percentage of octane = 100% - 45% = 55%
Total moles = 11.212 mol
Moles of hexane :
Moles of hexane = 5.0454 mol
Mass of 5.0454 moles of hexane,M = 5.0454 mol × 86 g/mol=433.9044 g
Density of the hexane,D =
Volume of hexane = V
(1 cm^3= 0.001 L)
The required volume of hexane is 0.66245 Liters.
