Answer:  0.695 mol/L

Explanation:

To find the final concentration of the solution, we must first identify the moles of the solute (NaNO₃):

   moles = mass ÷ molar mass

∴ moles of NaNO₃ = 325 g ÷ 84.995 g/mol

                              =  3.824 mol

Now, since the final volume is 5.5 L and this volume contains the 3.824 moles of NaNO₃,

then the molarity of the solution = 3.824 mol ÷ 5.5 L

                                                     =  0.695 mol/L

Three other application of Bernoulli's principle ?
Makovka662 [10]
<h2><u>Answer:</u></h2>

Bernoulli's Theorem in a general sense relates the weight, speed, and rise in a moving fluid (liquid or gas), the compressibility and consistency (internal grinding) of which are insignificant and the flood of which is predictable, or laminar.

(1): We can discover the speed of Efflux of a fluid.

This is given by v= sqrt (2gh), where the fluid is turning out from an opening in a vessel at profundity h from free fluid surface. This condition is known as Torricelli's hypothesis.

(2): Vena Contracta: The fluid stream from gap contracts at a separation minimal outside the opening to a neck, called Vena Contracta.

The territory of cross-segment of a fly is littler than a zone of opening. From this reality, we can discover the coefficient of withdrawal.

(3) : Bernoulli's standard is utilized in the development of Venturimeter, an instrument for estimation of measure of a stream of a fluid through a pipe.

In an aqueous solution at 25°C, if [H30+] = 3.3 * 10^4 M, then [OH-] is:
sleet_krkn [62]

Answer:

[OH-] = 3.0 x 10^-19 M

Explanation:

[H3O+][OH-] = Kw

Kw = 1.0 x 10^-14

[H3O+][OH-] = 1.0 x 10^-14

[OH-] = 1.0 x 10^-14 / 3.3 x 10^4 = 3.0 x 10^-19

A chemical reaction occurs when 2 white solids are stirred together they turn into a slushy white solid and the glass jar feels
Anestetic [448]

Answer:

Absorbed, endothermic

Explanation:

Based on the heat of reaction, chemical reactions may be classified as endothermic or exothermic.

In an endothermic reaction, heat is absorbed from the surrounding. As heat is absorbed from the surrounding, the reaction vessel feels cool when touched.

On the other hand, in an exothermic reaction, heat is given out by the system to the surrounding and the reaction vessel feels hot when touched.

Hence the reaction is endothermic and energy is absorbed during the reaction.
