Many kinds of data can be gathered in the study of ocean water. predictions are based on accurate and precise scientific data. which of these sets of data will yield the most precise data?
temperature readings that have a range of 2°c
depth readings that have a range of 4 km
salinity readings that have a range of 20%
density readings that have a range of 40 kg/l

temperature readings that have a range of 2°C

answer: blah

explanation:

bc blah

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.
