32 electrons. as the orbitals get father away from the nucleus, they hold more electrons.
5500 mg = 0.0055 kg. is the answer
Friction.
Friction prevents an object from being pushed or pulled along a horizontal surface.
5000L • 1 mole /22.4L so approximately 223 moles
Answer:

Explanation:
= Initial mass of water = 100 g
c = Specific heat of water
= Temperature difference of the initial mass of water = 
= Amount of water that is mixed = 75 g
= Temperature difference of the mixed mass of water = 
= Equilibrium temperature
The heat balance of the system is

The final temperature of the mixed water is
.
