The temperature of liquid nitrogen (LN), an inert cryogenic fluid, is 196 °C (320 °F). To drop the temperature of the concrete as much as is possible without causing it to freeze, LN is directly injected by lances into the batch water storage tank, the aggregate, or the mixer.
<h3>What is Cryopreservation ?</h3>
Cryopreservation is the process of preserving live cells, tissues, and other biological samples by placing them in a deep freezer at extremely low temperatures. The sample is typically stored at 196°C or lower. All of a cell's biological processes come to an end at such low temperatures, and the cell dies.
- Cells and tissues intended for transplantation are frequently stored via cryopreservation. A extremely stable ultra-low temperature environment is provided by liquid nitrogen. It is therefore employed for long-term storage.

Answer:
lets set the ratio -A/HA as R:
pH = pKa + log(R,10) => pKa + log10(R)
pH = 5.5
pKa = 4.76
R => 10^(pH - 4.76)
10^(pH - 4.76) => 5.4954
Given R (-A/HA) a number bigger than 1, then the concentration of -A is bigger than HA

Magnesium hydroxide react with hydrochloride to give magnesium chloride and water
THe word equation
magnesium hydroxide +hydrochroric acid---> Magnesium chloride+water
chemical equation
Mg(OH)2(S) + 2HCl (L)--> Mgcl2(S) + 2H2O(l)
when balancing the equation we count the number of molecules in the reactant side which should balance with molecules in the product side.
