Which option correctly shows the concentration of H₂O* ions in pure water? (1 point)

Physics

Lostsunrise [7]2 years ago
7 0

H2O is present at a calculated value of 1.0 x 107 moles per liter.

The balance of neutral water molecules and the ions they generate controls the chemistry of aqueous solutions.

H3O+(aq) + 2 H2O(l) + OH- (aq)

1.0 x 10-7 M [H3O+] = [OH-]

As a result, adding an acid to water affects the concentration of both H3O+ and OH- ions. Acids raise the concentration of the H3O+ ion in water since they are a source of this ion. However, the amount to which water dissociates is reduced when an acid is added. As a result, the concentration of the OH- ion significantly drops. The concentration of OH- ions rises as a result of adding a base. The H3O+ and OH- ion concentrations are combined to equal Kw once the system reaches equilibrium. Naturally, the only method to do this is to reduce the concentration of the H3O+ ion.

If you add air to a flat tire through a single small entry hole, why does the air spread out to fill the tire
Natali [406]
The tire fills up just like any thing else that holds air when u pump a ball or tire up it fills all the way up cause it is a small confined space and after filling it with air the atoms of the air fill the tire up

givi [52]

Answer:

\frac{1}{8} y'' + 2y' + 24y=0

Explanation:

The standard form of the 2nd order differential equation governing the motion of mass-spring system is given by

my'' + \zeta y' + ky=0

Where m is the mass, ζ is the damping constant, and k is the spring constant.

The spring constant k can be found by

w - kL=0

mg - kL=0

4 - k\frac{1}{6}=0

k = 4\times 6 =24

The damping constant can be found by

F = -\zeta y'

6 = 3\zeta

\zeta = \frac{6}{3} = 2

Finally, the mass m can be found by

w = 4

mg=4

m = \frac{4}{g}

Where g is approximately 32 ft/s²

m = \frac{4}{32} = \frac{1}{8}

Therefore, the required differential equation is

my'' + \zeta y' + ky=0

\frac{1}{8} y'' + 2y' + 24y=0

The initial position is

y(0) = \frac{1}{2}

The initial velocity is

y'(0) = 0
