Answer:
D. all of the above
Explanation:
The water molecules have surrounded salt (NaCl) ions in the given diagram.
Salt get dissolve in water as both are polar, having positive and negative charges and both have electrical charges. Covalent bonds in water molecules are more stronger than the ionic bonds of salts, that is why salt dissolve in water.
Water molecules and salt molecules form electrostatic interaction in which the positively charges ends of water molecules are attracted to the negative chloride ions (Cl- ion) while negative ends of the water molecules are attracted to the positive sodium ion (Na+ ion).
Water molecule breaks the ionic bond between sodium and chloride ions. Water molecules form hydration shell around sodium (Na+) and calcium (Cl-) ions and allow the salt to dissolve in water and forma homogeneous solution.
Hence, the correct option is "D. All of the above".
It is not what you thing it is but the answer is true
Osteoporosis, which literally means porous bone, is a disease in which the density and quality of bone are reduced. As bones become more porous and fragile, the risk of fracture is greatly increased. The loss of bone occurs silently and progressively.
Answer:
B
Explanation:
Convection occurs to divert heat generated by the core and spread through the mantle. at the bottom of the mantle, heat is gained, causing the mantle to be less dense and rise up. at the top, heat is subsequently lost, resulting in am increase of mass and a drop down for the mantle. this process repeats indefinitely
