Answer:
Temperature = 818 K
Explanation:
The given reaction is:
The change in enthalpy is: ΔH°= -109 kJ
The change in entropy is : ΔS° = -133.2 J/k = -0.1332 kJ/K
Based on the Gibbs-Helmholtz equation the standard free energy change is given as:
At equilibrium ΔG° = 0. therefore:
25.2 / 34.6 x 100
which would get you 73%

Answer:
66.7 g
Explanation:
Number of atoms = 2×10²¹
Mass of 2×10²¹ atoms = 0.4 g
Mass of 0.5 moles of that element = ?
Solution:
1 mole contain 6.022×10²³ atoms
2×10²¹ atoms × 1 mol / 6.022×10²³ atoms
0.33×10⁻² mol
0.003 mol
0.003 mole have mass of 0.4 g
0.5 mol have mass 0.5/0.003×0.4 g = 66.7 g
Answer:
D. Electrical energy
Explanation:
I assume you are talking about an electrical current.
(These are by what I know and are simplified, not an exact definition)
A. Mechanical energy is energy that something has because of motion.
B. Magnetism is the attracting and repulsing forces between magnets.
C. Geothermal energy is heat inside of the Earth. Used as source of power.
D. Electrical energy is the result of an electric charge.
Answer:
0.125. work- divide the volume value by 1000
873. work- multiply the length value by 100
98100. work- Conversion factor: 1 kg = 100000 cg
1) Centigram = Kilogram * 100000
2) Centigram = 0.981 * 100000
3) Centigram = 98100
285.65. work- 12.5°C + 273.15 = 285.65K
446.85. work- 720K − 273.15 = 446.85°C
346.25. work- 73.1°C + 273.15 = 346.25K
