Answer:
100.8 °C
Explanation:
The Clausius-clapeyron equation is:
-Δ
Where 'ΔHvap' is the enthalpy of vaporization; 'R' is the molar gas constant (8.314 j/mol); 'T1' is the temperature at the pressure 'P1' and 'T2' is the temperature at the pressure 'P2'
Isolating for T2 gives:
(sorry for 'deltaHvap' I can not input symbols into equations)
thus T2=100.8 °C
Answer:
2. 1 gram of Uranium (U)
Explanation:
1.
1 g Be x 1 mol/ 9.012182 g = 0.1109609193 mol Be
0.1109609193 mol Be x 6.0221409e+23/ 1 mol = 6.68x10^22 atoms of Be
2.
1 g U x 1 mol/ 238.0289 g = 4.20117053x10^-03 mol U
4.20117053x10^-03 mol U x 6.0221409e+23/ 1 mol = 2.53x10^21
3.
1 g S x 1 mol/ 32.066 g = 0.03118567954 mol S
0.03118567954 mol S x 6.0221409e+23/ 1 mol = 1.88x10^22
4.
1 g Fe x 1 mol/ 55.847 g = 0.01790606478 mol Fe
0.01790606478 mol Fe x 6.0221409e+23/ 1 mol = 1.078328451x10^22
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Your answer is x= 1/2, this is because to get the x alone you need to move the 2 so you divide 2x by to and you have to do the same to the other side so 1/2, and you get x=1/2
