0.02 mol NaCl
Explanation:
(0.2M NaCl)×(0.10 L) = 0.02 mol NaCl
The ideal gas law is: PV=nRT
Pressure
Volume
n= moles
R= gas constant
Temperature in Kelvin
(Degrees in celsius +273)
n= PV/RT
(1.00atm)(5.00L)/(.08026)(295K)= .207mol of gas
What is the element with 7 protons? They probably also have 7 neutrons. Just a ball park figure guess.
Answer:
Explain that as the water evaporates, water molecules go into the air. The water molecules that evaporate become a gas called water vapor. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re- form salt crystals.
