Ben measures the hight of two bottles one is 12 cm and one is 15 cm. What is the difference of the hight in millimeters

The answer is 30 millimeters.

Explanation:

For every 1 centimeter, it is 10 millimeter. So for 12 cm, its 120 millimeters. 15 cm, its 150 millimeters. 150 mm - 120 mm = 30 mm.

i am going to guess that it is co2.

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.
