Changes in temperature, salt concentration, ionic concentration, of pH levels
Answer:
Ant sting release methanoic acid or formic acid. The chemical formula of methanoic acid is HCOOH
Answer:
C. Cohesion of molecules
Explanation:
Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.
This phenomenon also called surface tension and is what allows small insects to stand on water.
Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.
Answer: neutral
Explanation: The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
