Red cabbage juice is a pH indicator.
Aluminum chloride is an ionic salt with the formula AlCl3. The reason for the three chlorine atoms is because aluminum donates an electron to each chlorine atom.
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:
Yes
Explanation:
Atoms are generally classified as pure substances. A pure substance has the following properties:
- All parts are the same throughout i.e. homogeneous
- They have definite composition
- The cannot easily be broken down into simpler substances by physical means.
- Separation by physical methods is not easy.
- They have unique sets of physical properties.
Elements and compounds are generally classified as pure substances. Since atoms are the building blocks of pure substances, they can be classified as one.
