Answer:
pH of 4
Explanation:
Upon comparing a solution with a pH value of 4 and that having a pH of 7, you will realize that it has a pH difference of 3 although the concentration of ions of hydrogen having a pH of 7 is 1000 times greater than being at a pH of 4.
<h2>Hello!</h2>
The answer is: H2O

Why?</h2>
The critical temperature (also known as the critical point) is the temperature above a vapor or gas can't be liquefied no matter how many pressure can be applied. Every substance has a critical temperature which varies according to the substance/compound nature.
For example, the water has a critical temperature of 373.94 °C, it means that above that temperature the vapor and liquid phases can't be distinct and there is no possible way that the vapor became liquid again no matter how many pressure is applied.
The critical temperature of the given elements/compounds are:
H2 : -240 °C
N2: -147 °C
NH3: 132.4 °C
H2O: 373.94 °C

Sedimentary <span>rock is formed when debris is buried, compressed and cemented together. It is formed as a result from the accumulation of sediment on landform or land mass, and then the cementation of the material. This causes the materials to permanently settle in place and turn into rocks.</span>
Hydraulic pressures caused by the migration of water molecules and alkali ions into the restricted spaces of the calcite/clay matrix around the dolomite rhombs.
