An air conditioner uses chemicals that allow for the cooling of warm air, which makes it condense. Using that process over and over again allows the air conditioner to take the warm air outside, and the cold air inside. That's especially useful in summer!
Have a nice day! :)
Answer:
b atoms
Explanation:
everything is made up of atoms
Answer:
1.014×10²³ atoms
Explanation:
Given data:
Volume of tungsten = 1.6 cm³
Density of tungsten = 19.35 g/cm³
Number of atoms of tungsten = ?
Solution:
First of all we will calculate the mass of tungsten.
density = mass/volume
by putting values,
19.35 g/cm³ = mass/1.6 cm³
Mass = 19.35 g/cm³× 1.6 cm³
Mass = 30.96 g
Number of moles of tungsten:
Number of moles = mass/molar mass
Number of moles = 30.96 g/ 183.84 g/mol
Number of moles = 0.1684 mol
1 mole contain 6.022×10²³ atoms.
0.1684 mol × 6.022×10²³ atoms / 1mol
1.014×10²³ atoms
The answer is 0. If a car goes north 50 mph and turns around and goes 50 mph south the car is back at its starting point therefore the car is back at 0. Hope this helps!
