If we dissolve 10 mL of acid into a beaker of water. The acid will be diluted.
Since the number of moles of acid will not change, we can use this formula:
M1 V1 = M2 V2

Where M is the concentration of the acid in the solution
V1 = 10 mL
and
V2 = Vwater + 10

If we add an additional 5 mL of acid, the new concentration of the acid will be:
M = (M1 (5mL) + M2 (Vwater + 10mL)) / (5mL + Vwater + 10mL)

The concentration of acid in the new solution will increase.

Compare a photon and quantum. How are they alike? How are they different?
mario62 [17]

Quantum is deemed to be a distinct container with energy kept in, whereas photon is considered as an elementary particle. Photon and quantum are two very significant principles talked about in modern physics. These principles are broadly used in quantum chemistry, quantum physics, electromagnetic theory, particle physics, optics, etc. These principles are also applied in a lot of actual world applications such as high resolution microscopy, LASERs, measurements of molecular distances, photochemistry, and quantum cryptography. It is highly important to have knowledge and a good understanding in photon and quantum so that we could excel in the aforesaid fields. A photon is an elementary particle, however, a quantum is not an elementary particle. A quantum does not have the properties of both wave like and particle like, but a photon does. A photon is not about a measure of quantity and can be defined as a quantum of energy, on the contrary, a quantum can be described as a measure of quantity.

The formation of tert-butanol is described by the following chemical equation:
fomenos

Answer:

Second step

(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)

Explanation:

This reaction involves;

First the ionization of the tertiary halide to firm a carbocation

Secondly the attack of the hydroxide ion on the carbocation to form tert-butanol

First step;

(CH3)3CBr (aq) → (CH3)3C+ (aq) + Br- (aq)

Second step

(CH3)3C+ (aq) + OH^-(aq) ------->(CH3)3COH(aq)

This second step completes the reaction mechanism.

What is packing fraction ?<br>state the formula used to calculate it.<br><br>thankyou ~​
slava [35]

Answer:

<h2><em>please</em><em> </em><em>mark</em><em> </em><em>me</em><em> </em><em>brainliest</em></h2>

Explanation:

<h2>Packing fraction is defined as a way of expressing the variation of isotopic mass from whole mass number (atomic mass). This fraction can have positive or can have negative sign. A positive packing fraction describes a tendency towards instability.</h2><h2>The equation for packing fraction is: Packing fraction = (N atoms) x (V atom) / V unit cell. N atoms is the number of atoms in a unit cell. V atom is the volume of the atom, and V unit cell is the volume of a unit cell. Substitute the number of atoms per unit cell into the equation.</h2>

Convert 90.23 kPa into atm
svlad2 [7]

Answer:

The answer is

<h2>0.89 atm </h2>

Explanation:

To convert from kPa to atm we use the conversion

101.325 kPa = 1 atm

If

101.325 kPa = 1 atm

Then

90.23 kPa will be

\frac{90.23}{101.325}  \\  =0.89050086...

We have the final answer as

<h3>0.89 atm</h3>

Hope this helps you
