PLSPLSPLS HELP ASAP a scientist discovers that the acidity of a lake increases overtime. at the same time, its population of Minnows grew smaller. when the adicity of the lake return to normal, The Minnow population recover.

In what two ways can the minnow population be used to monitor the Lakes water quality?

In the above case we can understand that,

what subject is this

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.
