What is a state function?

1 answer:

3 0

Is a function defined for a system relating several state variables or state quantities that depends only on the current equilibrium thermodynamic state of the system[1] (e.g. gas, liquid, solid, crystal, or emulsion), not the path which the system took to reach its present state. A state function describes the equilibrium state of a system, thus also describing the type of system. For example, a state function could describe an atom or molecule in a gaseous, liquid, or solid form; a heterogeneous or homogeneous mixture; and the amounts of energy required to create such systems or change them into a different equilibrium state.

Calculate density of aluminum if 27.6cm^3 has a mass of 74.6g

rjkz [21]

First , 27.6 cm^3 is equal to 27.6 ml

Density = mass g / volume cm^3

= 74.6 / 27.6 = ........ g/cm^3

Why is acetic anhydride added slowly to a dichloromethane solution of the other reactants?

storchak [24]

Acetic anhydride is the only monocarboxylic acid anhydride which is an acylating agent capable of modifying reactions. The dichloromethane is the reaction solvent.

The acetic anhydride should be added slowly through a separatory funnel to other reactants so as to avoid a runaway reaction, also known as thermal runaway. By doing this the reaction mixture boils as gently as possible while stirring. This phenomenon occurs in situations where an increase in temperature changes the conditions in a way that leads to destructive result brought about by a further increase in temperature.

Write the formula for a complex formed between zn2 zn2 and nh3nh3 with a coordination number of 3.

fredd [130]

Triammine zinc sulfate is the formula for a compound produced between zn2 and nh3 with a coordination number of 3.

<h3>Steps</h3>

Zinc atoms are present in the +2 oxidation state in zinc sulfate (ZnSO4).

Thus, a coordination complex formed by three ammonia ligands and zinc sulfate can be shown below.

NH3 + ZnSO4 = [Zn(NH3)] SO4

In its ionic form, this equation can be expressed as

Zn²⁺ + 3NH₃ = [Zn(NH₃)₃]²⁺

<h3>Coordination number: what is it?</h3>

The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.

<h3>What is a good illustration of a coordination number?</h3>

For instance, [Cr(NH3)2Cl2Br2] has the core cation Cr3+, which is referred to as hexacoordinate and has a coordination number of 6.
