A charasteristic of metals is that they lose easily electrons, cations tends to gain electrons to react and anions tends to lose or share electrons to react.
If you want to make a chemical reaction you must to mix a reagent that tends to lose electrons with other that tends to gain them.
In the statement (a) we have a metal that loses electrons and a cation that can obtain them, so is the right answer.
note that the other optios have :
b) Metal with metal cation, not react beacause left a medium of reaction.
c) Both loses electrons
d) Both tends to gain electrons.
This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. ... Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid.
Texas has a capital H over it. In weather, a capital red H is an area of high pressure. High pressure areas have sunny, warm weather.
