Answer:
Rubidium Acetate
Explanation:
Rb is Rubidium C2H3O2 is acetate
Answer:
pH = 5.58
Explanation:
Given that :
Citric acid is a triprotic acid with the formula 
. Tripotic acids are acids that have the tendency to yield three protons per molecule during the phases of dissociation, therefore they have three pka.
For Citric acid; the pka values are:
So, the pH of sodiummonohydrogencitrate with the chemical formula 
which can act as an acid and a base (i.e it is said to be amphoteric) can be calculated as :
pH = 5.58
Therefore, the approximate pH of a solution of sodium monohydrogencitrate = 5.58
Is this a test or something else?
Explanation:
The prefix trans- and its variant tra- mean "across".
A translucent substance allows some light to go "across" it to the other side. Also, think about a transparent substance: it allows light to go "across" it; or a translation, it is a going "across" from one language into another.
Answer:
The track of the Moon's shadow across Earth's surface is called the Path of Totality. This path is typically 16,000 kilometers (about 10,000 miles) long but only 160 kilometers (100 miles) or so wide. In order to see the Sun totally eclipsed by the Moon you must be in the path of totality.
