Answer:
The pressure in the container is 1,7 atm.
Explanation:
We convert the unit of temperature in Celsius into Kelvin:
0°C= 273K --> 45°C= 45 + 273= 318 K
We use the formula:
PV=nRT ---> P =nRT/V
P= 1,20 mol x 0,082 l atm/K mol x 318 K/18,0 L
<em>P= 1, 7384 atm</em>
in the phase diagram the line between solid and liquid is where both phases available at the same time
Barium (Ba) has the lowest electronegativity of the choices you have given.
The electronegativity of Calcium (Ca) is 1
The electronegativity of Strontium (Sr) is 0.95
The electronegativity of Magnseium (Mg) is 1.31 (has the highest)
The electronegativity of Barium (Ba) is 0.89
Of the list above, you can see that Barium has the lower level of electronegativity (0.89). Therefore, the correct answer is D.
