Answer:
Explanation:
a self-contained convective zone in a fluid in which upward motion of warmer fluid in the center is balanced by downward motion of cooler fluid at the periphery.
Answer / explanation:
How does concentration affect boiling point of a solvent?
The amount by which the boiling point is raised is directly dependent on the concentration of the solute.
The higher the concentration of a solute, the more it is said to be difficult for the solvent molecules to escape into the gas phase.
However, when a non volatile amount of substance is dissolved in a given solvent, the boiling point of the given solvent increases.
The higher the concentration, the more higher the boiling point of a solvent.
It requires a higher temperature for enough solvent molecules to escape , this the boiling point is raised elevatedly
NaHCO3 is the right answer
Answer:
Exothermic reaction
Explanation:
Exothermic reaction is a reaction in which energy is evolved from the reaction to the surroundings
