Nobel gas, it is in the last row of the periodic table and therefore is a noble gas
Answer:
mass (g) needed = 710.2 grams Na₂SO₄(s)
Explanation:
Needed is 2.5 Liters of 2.0M Na₂SO₄; formula wt Na₂SO₄ = 142.04g/mol.
mass (grams) of Na₂SO₄(s) = Molarity needed x Volume needed in Liters x Formula Wt of solute
mass (grams) of Na₂SO₄(s) = (2.5L)(2.0M)(142.04g/mol) = 710.2 grams Na₂SO₄(s)
Mixing: Transfer 710.4 grams Na₂SO₄ into mixing vessel and add water-solvent up to but not to exceed 2.5 Liters total volume. Mix until dissolved.
Gives 2.5 Liters of 2.0M Na₂SO₄(aq) solution.
Answer: The pressure of nitrogen will be 2.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.0 atm
V = Volume of gas = 10.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Now again using ideal gas equation :
Thus pressure of nitrogen will be 2.0 atm
In gases the only thing that isn't related is acidity.
Thermal energy
Explanation: Heat is being created because you have turned the stove on. When heat is involved it is Thermal energy.
