The rock dwelling lizards would lose their hiding/refuge places from other prey and also for shade from the intense sun so their prey would be able to capture them easily which could result in over eating of them and then their decimation and resultant loss of sustainable food for the prey thus resulting in dying off of the prey as well or migration to other areas where the rocks still existed and the lizards.
it is water because it is dissolving the sodium chloride
Answer:
See explanation
Explanation:
A drying tube prevents moisture from contaminating the reactants. The drying tube contains CaCl2 a hygroscopic material whose function is to absorb the moisture so that it does not react with the Grignard reagent. Without the desiccating action of CaCl2, moisture will enter the reaction chamber,contaminating the reactants.
If water reacts with the Grignard reagent, an alkane is formed. The mechanism of this reaction is shown in the image attached. R here represents the alkyl moiety of the Grignard reagent.
