Answer:
Laws governing gas behavior.
Explanation:
Boyle's law:
It relates the pressure and volume of an ideal gas at a constant temperature.
According to this law:
"The volume of a fixed amount of gas at constant temperature is inversely proportional to its pressure".
.
Charle's law:
It relates the volume and absolute temperature of an ideal gas at a constant pressure.
According to this law:
"The volume of a fixed amount of gas at constant pressure is directly proportional to its absolute temperature".
.
Avogadro's law:
According to this law:
equal volumes of all gases under the same conditions of temperature and pressure contain, an equal number of moles.
.
Ideal gas equation:
By combining all the above-stated gas laws, this equation is formed as shown below:

R is called universal gas constant.
It has a value of 0.0821L.atm.mol-1.K-1.
Barium has a 2+ charge as it is in group 2 in the periodic table and so it has two electrons in its outer shell and chloride has a -1 charge on its chloride ion. So we will need two of the chloride ions as we have a 2+ charge to match the amount of charge on one barium ion- forming barium ion
BaCI2
Answer: n= 0.045 mol
Explanation: amount of substance in moles is n= cV= 0.30 mol/l· 0.150 l
Answer:
( A ) Increases
Explanation:
More room, basically means more creatures. Like in a bedroom, you can only fit amount of people if its small the ocean is like that with depth.
Hopefully this makes sense???
