Covalent bonding - giant covalent structures. ... The atoms are usually arranged into giant regular lattices - extremely strong structures because of the many bonds involved. The graphic shows the molecular structure of diamond and graphite: two allotropes of carbon, and of silica.
Answer: please make the question more understandable
Explanation:
Answer: (c) CHCl3
Explanation:
From the rule : a polar solvent will dissolve a polar compound and a non polar solvent will also dissolves a non polar compound.
(a) CH4 is non- polar and water is a polar solvent. Therefore CH4 is not soluble in water
(b) CCl4 is non polar and water is a polar solvent. Therefore CCl4 is not soluble in wtaer
(c) CHCl3 is polar molecule and water is also a polar solvent.
Therefore CHCl3 is expected to be most soluble in water
Answer:
Organ systems & their main functions
Explanation:
The chest bones Rib Cage & spine - protects the vital organs (heart, lung,liver) from injury & provides structural support for body.
Skin is the body's first line of defense & keeps the body warm. In case of any invading infection, fever - body temperature rise fights it.
Circulatory system (containing heart) & its body fluid blood - transports nutrients and oxygen to body cells
