Answer:
278 balloons can be aired.
Explanation:
We apply the Ideal Gases Law to determine the total available volume for each baloon of 0.75L. So we need to divide the volume we obtain by the volume of each baloon.
We determine the moles of CO₂
375 g. 1 mol / 44g = 8.52 moles
V = (n . R . T) / P → (8.52 mol . 0.082 . 298K) / 1 atm = 208.3 L
That's the total volume from the tank, so we can inflate (208.3 / 0.75) = at least 278 balloons
Answer:
Intermolecular bonds are found in all of them. They can come in different versions.
Answer:
density = 4.763pounds per liter
Explanation:
1g/cm³ = 2.205pounds per liter
2.16g/cm³ = (unknown)pounds per liter
(unknown)pounds per liter = 2.205 x 2.16 = 4.763
density = 4.763pounds per liter
Answer:
Specific gravity is the density of asubstance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density(but without any units).
The definition of heat transfer through convection involves the movement of a fluid that causes heat to move away from a hear source. That being said, convection can take place in a lake, air inside, and air outside since both liquids and gasses are considered to be fluids.
I hope this helps.
