(A) gas to liquid
is most likely to take place. This change from gas to liquid is the forming of water molecules. Gas particles have the most energy and therefore speed up the most, whereas solids have the least amount of energy and slow down. The intermediate step from gas to solid is a liquid. We call this process from gas to liquid condensation.
<span>1.75 mol H2O x (6.022x10^23 molecules H2O / 1 mol H2O) = 1.05x10^24 molecules H2O if you need a further example let me know </span>
Answer:
north pole, south pole, and magnetic field
Explanation:
the earth basically has a giant bar magnet inside it( the axis). Earth has a north pole, a south pole, and a magnetic field which are the same things that a bar magnet has.
Answer:
d= 50.23 g/cm³
Explanation:
Given data:
radius = 137.9 pm
mass is = 5.5 × 10−22 g
density = ?
Solution:
volume of sphere= 4/3π r³
First of all we calculate the volume:
v= 4/3π r3
v= 1.33× 3.14× (137.9)³
v= 1.33 × 3.14 × 2622362.939 pm³
v= 1.095 × 10∧7 pm³
v= 1.095 × 10∧-23 cm³
Formula:
Density:
d=m/v
d= 5.5 × 10−22 g/ 1.095 × 10∧-23 cm³
d= 5.023 × 10∧+1 g/cm³
d= 50.23 g/cm³
