Answer:
A,C
Explanation:
Because the other question deal with convection but A,D show how the warm and cold water travel .
Answer:
option c
Explanation:
Solution is formed when a solute is dissolved a solvent.
Formation of solution is decided by the interaction between solute and solvent.
When a solute is dissolved, the intermolecular interactions in between solute molecules are broken. And New interactions are formed between solute and solvent.
In order to form solution, the solute-solvent interactions must be stronger than solute-solute and solvent-solvent in interactions.
Therefore, among given the option c is correct.
Think, first, about the type of molecule or formula unit you have (covalent or ionic). In this case, it is a covalent molecule. You start with the carbon. You could say monocarbon, but if it is just said to be carbon it is assumed to be one. Then you take the prefix for 4 and tack it on to the beginning of the chlorine. For this, the name is carbon tetrachloride.
