Answer:

Yes, diamond can be burned. The most common form of burning in everyday life is carbon combustion. In carbon combustion, carbon atoms break their bonds with each other and with other atoms (which requires energy) to form bonds with oxygen atoms (which releases even more energy than first required). The net extra energy released in this reaction can then go on to rip more carbon atoms free of their non-oxygen neighbors, thus continuing the reaction, or the energy can escape as heat and ligh

Use the standard free energies of formation (ΔGf°) of each substance to determine the value of equilibrium constant K at 25 °C f

Greeley [361]

Answer:

k = 8,83x10³⁹

Explanation:

For the reaction:

CO₂(g) + 2H₂(g) ⇌ CH₃OH(l)

ΔG° = ΔGproducts - ΔGreactants

ΔG° = ΔGCH₃OH(l) - (ΔGCO₂(g) + 2ΔGH₂(g)

As ΔGCH₃OH(l) = -166,4 kJ/mol; ΔGCO₂(g) = -394,4 kJ/mol; ΔGH₂(g) = 0 kJ/mol

ΔG° = -166,4 kJ/mol - (-394,4 kJ/mol + 2×0 kJ/mol)

ΔG° = 228,0 kJ/mol

The ΔG could be defined as:

ΔG = -RT lnK

Where R is gas constant (8,314472x10⁻³ kJ/molK); Temperature is 25°C, 298,15K.

Replacing:

228,0 kJ/mol = 8,314472x10⁻³ kJ/molK×298,15K ln K

91,97 = ln k

K = 8,79x10³⁹ ≈ 8,83x10³⁹

I hope it helps!

Using the table on the right, complete each calculation by typing in the correct answer. 13.2 L = mL Metric Values

kirza4 [7]

Answer : 13.2 Liter is equal to the 13200 milliliter

Solution :

To convert the given quantity into milliliters, we use the conversion :

1 liter = 1000 milliliter

As, 1 liter is equal to 1000 milliliter

So, 13.2 liter is equal to $\frac{13.2liter}{1liter}\times 1000ml=13200$ milliliter

Therefore, 13.2 Liter is equal to the 13200 milliliter
