<h3><u>Answer;</u></h3>

D. It decreases and the pH increases.

<h3><u>Explanation;</u></h3>
  • pH is a measure of the hydorgen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH.
  • <em><u>[H+] and [OH-] are inversely related. Therefore; As the concentration of H+ increases the pH decreases. Since the concentrations of H+ and OH- are inversely proportional, as one goes up, the other goes down. </u></em>
  • <em><u>Therefore, an increase in OH- concentration will correspond to an increase in pH and a decrease in the concentration of H+.</u></em>

Answer : The correct option is, (A) It increases and the pH increases.

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Mathematical expression is,

pH=-\log [H^+]

pH is indirectly proportional to the concentration of hydrogen ion.

As per question, when the concentration of hydrogen ion decrease that means the the value of pH increases. When the value of pH increases that means the solution is basic and the concentration of hydroxide ion increases.

Hence, as the [H^+] in a solution decreases, the [OH^-] increases and pH also increases.

What is the difference between breccia rock and conglomerate rock
Klio2033 [76]
Breccia rocks and conglomerate rocks are said to be very similar rocks. They both are sedimentary rocks. Their difference lies on their shapes. For breccia rocks, large particles are angular in shape which is different from the conglomerate rocks where they are rounded.

A loss of electrons by an atom creates an anion? <br> true or false
Nostrana [21]
That is false.

An ion is "<span>an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons."

But in detail anion means gaining of electrons.

So, a gain of electrons by an atom creates an anion.</span>

Both isopropyl alcohol, C3H8OH, and ethylene glycol, C2H6O2, are used as antifreeze. When equal masses of each are added to wate
kiruha [24]
I believe the correct answer from the choices listed above is option B. When equal masses of each are added to water, ethylene glycol would be more effective. Ethylene glycol is the most widely used automotive cooling-systemantifreeze, although methanol, ethanol, isopropyl alcohol, and propylene glycol are also used.
Hope this answers the question. Have a nice day.

Which is a characteristic of nuclear fission
icang [17]
1. A heavy nucleus (U235 or Pu239), when bombarded by slow moving neutrons, split into two
or more nuclei.
2. Two or more neutrons are produced by fission of each nucleus.
3. Huge amount of energy is produced as a result of nuclear fission.
4. All the fission fragments are radioactive, giving off β and radiations.
<span>5. The atomic weights of fission products range from about </span>70 to 160.
6. The nuclear chain reactions can be controlled and maintained steadily by absorbing a
desired number of neutrons. This process is used in nuclear reactor.
<span>7. All the fission reactions are self-propagating chain-reactions because fission products contain </span>
neutrons (secondary neutrons) which further cause fission in other nuclei.
8. Every secondary neutron, released in the fission process, does not strike a nucleus, some
escape into air and hence a chain reaction cannot be maintained.
<span>9. The number of neutrons, resulting from a single fission, is known as the multiplication factor. </span>
When the multiplication factor is less than 1, a chain reaction does not take place.
<span>10. The control of chain reaction is necessary in order to maintain a steady reaction. This is </span>
carried out by absorbing a desired number of neutron by employing materials like
percentage of Cd, B or steel.
11. In a nuclear reactor, the multifactor is one. This is achieved by proper arrangement of
<span>fissionable materials.</span>
