the graph shows the relationship between the number of cigarettes smoked per day and the increased risk of lung cancer what name is given to this type of correlation

Positive correlation

Explanation:

When one variable increases, the other increases as well. In this case, a higher number of cigarettes smoked per day will see an increased risk of lung cancer as well.

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.
