Planck’s constant relates the joules of energy absorbed/released by matter to the ________. atomic number of the element frequen

mamaluj [8]

Planck’s constant relates the joules of energy absorbed/released by matter to the wave frequency f. the plancks constant was first recognized in 1900 by Max Planck. The equation that relates the joules of energy absorbed/released by matter to the wave frequency f is called the plancks-eintein relation, E = hf

To a 0.0001 m solution of mg(no3)2, naoh was added to a final concentration of 0.001m did a precipitate form?

Natalija [7]

I looked on a solubility chart to answer this question, and hydroxides are generally insoluble (with some exceptions of course). However, it says to consider $Mg(OH)_{2}$ as an insoluble substance, though it may be moderately soluble.

The answer that you are most likely looking for is: Yes, a precipitate does form - this is due to the double placement reaction:

$Mg(NO_{3})_{2}_{(aq)}$ + $2NaOH_{(aq)}$ → $Mg(OH)_{2} {(s)}$ + $2NaNO_{3}_{(aq)}$

Why can’t you perform single displacement reactions with group IA metals?

pishuonlain [190]

Answer is: because alkaline metals (group IA metals) are the strongest reducing agents and most reactive metals.
Reducing agent is an element or compound that loses an electron to another chemical species in a redox chemical reaction and they have been oxidized.
Alkaline metals tend to lose only one electron in redox reaction.
