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;
= g/cm^3
Explanation;
-Density is the mass per volume of a substance, or the weight per volume of an object. The Metric System is a type of system of measuring that uses only one root word for each basic dimension, such as, -gram for mass or -meter for distance.
-Metric system densities are usually in the units of mass per volume, such as g/cm^3 (gram per cubic centimeter). Where grams represents the units of mass and cm^3 represents the volume.
Answer:
Boron has 3 valence electrons
Answer:
the new concentration is 0.60M
Explanation:
The computation of the new concentration is shown below;
We know that
M1V1=M2V2
(3.0M) (10.0 mL) = M2 (50.0mL)
30 = M2 (50.0mL)
So, M2 = 0.60 M
Hence, the new concentration is 0.60M
