What is the parameter for finding the ∆H of a body...?

HELPPPPPPPPPPPPP PLEASE. Name the three different groups organisms are placed in based on how they get their food. Explain how t

Ket [755]

Answer:

Producers, consumers and decomposers

Explanation:

Producers can make their own food by capturing the sun's energy, but consumers and decomposers can't. Consumers need to eat other organisms to obtain energy. Decomposers are like the recyclers of nature. They obtain energy for their own needs while returning simple molecules to the environment.

Why is acetic acid written as hc2h3o2 rather than c2h4o2?

Naddik [55]

<span>Acetic acid is under the family of carboxylic acids which has a carboxyl group –COOH bond attached to the alkyl group. Alkyl group can be methyl (CH3-), ethyl (CH3CH2-) and so on. The term acetic also means methyl. So combining the two gives CH3COOH or HCH3CO2. The H before the C in <u>H</u>CH3CO2 means that it is the H attached to the O in the carboxyl group –COOH. You cannot write it as C2H4O2 because it would represent a different compound.</span>

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:

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.
