Answer:

Zero

Explanation:

The oxidation state of an element that is not involved in bonding is zero. An atom in its free and uncombined state has zero oxidation number.

The extent of oxidation of each atom of the elements in a molecular formula or formula unit or an ionic radical is given by the oxidation number.

The formal charge assigned to an atom present in a molecule or a formula unit or ion based on some arbitrary rules is given by the oxidation number.
Elements in their uncombined state or one whose atom combine with themselves to form molecules have zero oxidation number.

Answer:

${ \rm{F _{2(g)} + 2KCl _{(aq)} → { \bold{2KF _{(g)} + Cl_{2(g)} }}}}$

Explanation:

» The prediction is 98% correct because single displacement reaction type is highly possible.

This is because Fluorine has is more electronegative than Chlorine in Potassium Chloride. So, it strongly displaces Chlorine from the solution hence forming Chlorine gas.

» The 2% of wrong prediction maybe because of wrong reactant measurements following mole concept chemistry.

If you are asked the observation,

Observation » A green yellowish gas is formed.

This gas is Chlorine gas (Cl2)

Luden [163]

The Henderson-Hasselbalch approximation is for conjugate acid-base pairs in a buffered solution. We're going to call HA a weak acid, and A- its conjugate base. The equation is as follows:
pH = pKa + log([base]/[acid]), where the brackets imply concentrations
Plugging in our symbols and the pKa value, the equation becomes:
pH = 4.874 + log([A-]/[HA])

Which transition in the hydrogen atom produces emitted light with the longest wavelength?

monitta

Answer:

Red light has the longest wavelength

Explanation:

Red light is emitted when a high energy state electron drops from high energy level 3 to low energy level 2. Red light has the longest wavelength and lowest energy. It is a know fact that the shorter the drop within energy levels, the lesser the energy.
