How do plants and fish impact the pH of the lake?

pH and Ammonia

Strong acids and bases can dissolve into water and change the water's pH level. Rocks, chemicals, and even adding or removing fish from your fish tank can alter the level of pH in the water. This affects other chemicals present in the water, such as the ammonia from fish waste.

Therefore, when plants absorb carbon dioxide, thus removing it from the water, the pH will rise. You actually can measure water's carbon dioxide content indirectly by measuring changes in pH.

Explanation:

rocks and weathering-matching

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
