Determine the number of atoms in 0.075 mol of Carbon (C)? please help

nignag [31]

It would be C, 6.2 x 10^23.

Avogadro's number, or, the mole, is 6.02 x 10^23. Although the grams and molar mass of an element may be different, every element must have the same amount of atoms to obey avogadro's number.

To determine the enthalpy and entropy of dissolving a compound, you need to measure the Ksp at multiple _______. Then, plot ln(K

Aloiza [94]

Answer:

To determine the enthalpy and entropy of dissolving a compound, you need to measure the Ksp at multiple temperatures. Then, plot ln(Ksp) vs. 1/T. The slope of the plotted line relates to the enthalpy (ΔH) of dissolving and the intercept of the plotted line relates to the entropy (ΔS) of dissolving.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us use the thermodynamic definition of the Gibbs free energy and its relationship with Ksp as follows:

$\Delta G=-RTln(Ksp)\\\\\Delta G=\Delta H-T\Delta S$

Thus, by combining them, we obtain:

$-RTln(Ksp)=\Delta H-T\Delta S\\\\ln(Ksp)=-\frac{\Delta H}{RT} +\frac{T\Delta S}{RT} \\\\ln(Ksp)=-\frac{\Delta H}{RT} +\frac{\Delta S}{R}$

Which is related to the general line equation:

$y=mx+b$

Whereas:

$y=ln(Ksp)\\\\m=-\frac{\Delta H}{R} \\\\x=\frac{1}{T} \\\\b=\frac{\Delta S}{R}$

It means that we answer to the blanks as follows:

Regards!

What is the [OH-] if the [H3O+] is 1 x 10 -10?

anastassius [24]

The answer is [OH⁻] = 1 x 10⁻⁴.

[OH⁻] = H₂O ÷ [H₃O⁺]

[OH⁻] = 1 x 10⁻¹⁴ / 1 x 10⁻¹⁰

[OH⁻] = 10⁻⁴

tatuchka [14]

Answer:

Explanation:

If you added the reactants on the reactant side because there is one atom for nitrogen on the product side while there is two atoms on the product side. There are more hydrogen products on the reactant side as well.
