Classify each of the following as either macroscopic, microscopic or particulate: a red blood cell a mercury atom liquid mercu

Red blood cell is microscopic structure

Mercury atom is particulate

Liquid mercury is macroscopic

Explanation:

The three levels of organization is microscopic, macroscopic and particulate. The substances that can be seen by naked eyes is Macroscopic structures.

Example: Liquid mercury as it can be seen through naked eyes.

A mercury atom is a particulate matter which has not been sees by eyes or it can only be seen by electron microscope.

Red blood cells are very tiny and can be seen only in microscope.

the correct answer is b

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.
