5. Some undiluted acids are more corrosive when diluted
wlad13 [49]

Answer:

The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

Explanation:

Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.

When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe  if any splash self before washing.

Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.

arsen [322]

Answer and Explanation:

Throughout the world, the most different species of organisms are insects.  As compared to the other species, the number of insect species is greater. The exact number of insect species can be estimated from previous and current studies. Approximately nine hundred thousand species of insects are known. Insectivorous birds are those birds that feed on insects. For numerous growing insectivorous birds, insects are used as a source of protein.  One of the most common kinds of insects is beetles. They are found everywhere.  Beetles eat fruits, leaves, and other parts of the plant. The reproductive and fertility ability of insects is remarkable. In habitat 2, beetles and insectivorous birds were living. If all insectivorous birds and remaining beetles were removed from habitat, two and five hundred additional light tan beetles and 500 dark brown beetles were released in habitat 2. After one more week, one thousand dark brown beetles would be expected to be recaptured in the habitat 2.
