The formula for Gibbs free energy is G = H - TS

<u>Explanation: </u>

Gibbs free energy refers a form of thermodynamic potential like Helmholtz free energy. It depends on state functions like internal potential energy, pressure, volume, temperature and entropy.

Mostly, it is the measure of reversibility or spontaneity of the chemical reaction. The change in the Gibbs free energy between the reactants and products should be less than zero or minimised to have a spontaneous or reversible chemical reaction.

The mathematical representation is,

                               G = H - TS

Here, H= U+PV, H is the enthalpy of the reaction, the measure of heat energy required to start a chemical reaction, T is the temperature and S is the entropy, the measure of randomness caused in the chemical reaction.

Name the functional group in the<br> following molecule:
Anna71 [15]

Answer:

B. Aromatic

Explanation:

Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.

For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.

What mass of sodium chloride contains 4.59 x 10 24 formula units?
shtirl [24]
The term formula units means molecules.

Then, what you are looking for is the mass in 4.59*10^24  molecules.

The procedure involves to convert the 4.59 * 10^24 molecules into moles and use the molar mass of the sodium chloride.

1) Number of moles = 4.59 * 10^24 molecules / (6.02 * 10^23 molecules/mol) = 7.62 mol

2) Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol

3) mass of NaCl = molar mass *  number of moles = 58.44 g/mol * 7.62 mol = 445.31 g of NaCl

Answer: 445.31 g of NaCl.
