Why can mosquitos stand on water? A-The mosquito is able to walk on the water due to the attraction between multiple water molecules, creating surface tension.
B-The mosquito is able to walk on the water due to the attraction between water molecules and other non-water molecules, creating surface tension.

Mosquitos can stand on water because;

A. The mosquito is able to walk on the water due to the attraction between multiple water molecules, creating surface tension

Explanation:

Surface Tension is the surface property of a liquid which is due to the cohesive forces of attraction between its molecules, that enables it to withstand an external shearing force

The molecules in a liquid maintain a cohesive force between adjacent molecules that keeps all the molecules together such that the liquid has a defined volume

On the surface of the liquid, the cohesive forces between the molecules are shared by only between the adjacent molecules and molecules which are under the surface, and therefore, the attraction is much stronger such that the surface of the liquid is in tension, which is called the surface tension of the liquid

Therefore, the mosquito is able to walk on the water due to the attraction between multiple water molecules, creating surface tension.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

since electrons are negative the answer is neagtaive
