Answer:
-2
Explanation:
Gibbs free energy is defined by enthalpy of the system minus the product of the temperature and entropy and represented by the formula below:
G = H - TS where G = Gibbs free energy, H = enthalpy and T = temperature and S = entropy
change in entropy is defined by the formula below
ΔG = ΔH - Δ(TS) if the temperature is not constant, but if the temperature is constant then
ΔG = ΔH - TΔS
in according to the question (TS) is treated together.
to the solution
increase in H = 10 units , increase in the product of temperature and entropy = 12 units
ΔG = 10 - 12 = -2
To accurately measure the final volume of a solution in a burette, it is important that you read of the measurement in the lower meniscus like for water and for substances like mercury you read it on the upper meniscus. This is the standard way of reading volumes in laboratory apparatus. Also, it should be that the apparatus standing vertically in a plain surface.
Well the group fluorine is in is known as Halogens. Halogens all have seven valence electrons in their outer shell. They exist as diatomic molecules. Furthermore they readily combine with metals to form salts
While metal B is being reduced from an ion to a solid metal, metal A is being oxidized.
Metal A is being displaced because, through oxidation, it transforms from a solid metal to ions in a solution.
What is Oxidation ?
Redox reactions include a change in the oxidation state of the substrate. Loss of electrons or a rise in an element's oxidation state are both considered to be oxidation.
Gaining electrons or lowering the oxidation state of an element or its constituent atoms are both examples of reduction.
In general, the term "reduction" refers to a reaction in which a chemical receives additional electrons; the compound that gets electrons is referred to as being reduced. We can think of the transformation of a ketone or an aldehyde into an alcohol as a two-electron reduction because hydride can be thought of as a proton plus two electrons.
So finally we can say that Metal A is being oxidized.
