The first one that comes to mind is hydrochloric acid, which is essential to digestion.
1. A cave is non ventilated volume and the concentration of radon is greater than outdoor. 2. Determination of radon concentration (in Bq/m3 or in pCi/L). The maximum concentration should be under 150-250 Bq/m3.
The pH of the water will increase when elodea is exposed to light. This is because during photosynthesis, elodea will take in carbon dioxide, which will result in a decrease in carbonic acid concentration, leading to an increase in pH.

The minimum concentration of alcohol in water that is flammable typically starts around 50% alcohol by volume (ABV) for ethanol. At this concentration, the mixture can produce enough vapor to ignite when exposed to an open flame or spark. However, lower concentrations can also be flammable under certain conditions, particularly if the mixture is heated or if the vapor concentration is high enough. Always exercise caution when working with flammable substances.
The leaves of a plant not exposed to sunlight will likely be pale or yellowish in color due to the lack of chlorophyll production. Chlorophyll is responsible for the green color of leaves and is essential for photosynthesis, which requires sunlight to occur.

TFA is pretty nasty, so I'll go with that.
That depends on what type of insulation you're talking about. Exposed foam insulation generally isn't dangerous. Exposed asbestos insulation might be.

Phosphorus has a faint glow when exposed to oxygen.
Exposed to hazard; dangerous; risky.
The concentration of vitamin C in the solution decreases.
At risk; exposed; unsafe; unprotected; unguarded; vulnerable; insecure; harmful; dangerous.
Cytolysis does not happen in the elodea because of the concentration of its cells. The concentration that surrounds the cells are usually less concentrated and therefore prevent cytolysis from occurring.
Sure: Carbon monoxide is dangerous!
NO it is dangerous.
