There are several ways to prevent rusting. But you first need to know that rusting is caused by surrounding elements(wind,water,cold/heat etc)
So to prevent it, you need to have a coating protecting what you want to protect.
Some ways are to apply anti-rusting oil which is coating and another way I know that I know that they do for large buildings/structures such as bridges(the Golden gate bridge in San Fransisco is no exception) is to apply a special paint that protects then from rusting. But if there is even a little chip or crack in the paint, it can cause rusting in that area and slowly go under the paint and spread so workers have to sometimes repaint those spots to get rid of the rust.
Answer:
Sodium
Explanation:
Sodium is a pure chemical, hence it can be represented by the single chemical symbol Na.
Water has a chemical symbol of H2O, consisting of two, and not one, symbols, H and O.
Sulfate ion consists of a sulfide ion and four oxygen ions (SO4)2-. Hence, it does not fit.
Finally, potassium chloride has a chemical symbol of KCl. Consisting of two different chemical symbols, (K and Cl), it does not fit either.
Hope this helped!
Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.
