Answer:
ΔG = -105.4 kJ/mol
The system is spontaneous as written.
Explanation:
Step 1: Determine Gibbs free energy of reaction (ΔG)
We use the following expression.
ΔG = ΔH - T × ΔS
where,
ΔG = ΔH - T × ΔS
ΔG = 120.5 kJ/mol - 298 K × 0.7582 kJ/mol.K
ΔG = -105.4 kJ/mol
Step 2: Determine the spontaneity of the system.
Since ΔG < 0, the system is spontaneous as written.
Answer:
B.111
Explanation:
Atomic mass = number of protons(or atomic number) + number of neutrons
186 = 75 + number of neutrons
number of neutrons = 186 -75 = 111
Answer:
The formal thinker would take a systematic approach in the combination of the liquids, thereby eliminating several unnecessary combinations that the concrete thinker would definitely combine.
Explanation:
The formal operational stage in thinking begins when a child gets to the age of 12 and continues to adulthood. The formal operational stage provides an individual with the ability to think abstractly by manipulating ideas in their head without concretely manipulating it. A concrete would have to see something to be able to manipulate any ideas.
The movement of rock pieces and other materials on earth's surface is called Weathering
False.
