Industrially, vanadium metal can be obtained by reacting vanadium(V)oxide with
calcium at high temperatures:
5Ca + V205 → 5CaO + 2V
In one process, 1540 g of V2O5 react with 1960 g of Ca. (a) Calculate the mass of vanadium
formed. (b) How many grams of the excess reagent is left at the end of the reaction?

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

have a great day because if you dont you and i will be sad

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
