Answer:
Explanation:
Hello,
In this case, considering the given specific gravity we are to compute the density of the 64% HNO3 solution:
In such a way, since the given solution of nitric acid is 64 % by mass, we've got:
Thus, by using the previously computed density and the molar mass of HA (90.2 g/mol) we can compute the required molar concentration as follows:

Answer: Many elements produce colors in the flame when heated.
Explanation:
The origin of this phenomenon lies in the arrangement, or “configuration” of the electrons in the atoms of the different elements In the flame test, if this energy has the form of visible light, the flame will produce a color characteristic of the element.
Between a water molecule and an anion, like Cl-, a hydrogen bon occurs between hydrogen atom of the water molecule and the anion.
<h3>What is hydrogen bond?</h3>
Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Hydrogen atom in water molecule attract anion due to presence of hydrogen bond.
So we can conclude that hydrogen bond occurs between hydrogen atom of the water molecule and the anion.

Answer:
9.54
Explanation:
Fr the question given above, the following data were:
Concentration of hydronium ion [H3O⁺] = 2.9x10¯¹⁰ M
pH =?
The pH of the solution can be obtained as follow:
pH = –Log [H3O⁺]
pH = –Log 2.9x10¯¹⁰
pH = 9.54
Thus, the pH level of the solution is 9.54
