Answer:
13
Explanation:
atomic molar mass of 27 grams per mole. Al has 13 protons (hence number 13) and it most common ...

See explanation
Explanation:
Surface area has to do with the number of solid particles that are exposed at a given time and is capable of colliding with other reactant particles. When more surface area is exposed for reaction, then it means that more particles are likely to collide with each other leading to faster chemical reaction rates. When few particles are exposed for reaction (low surface area) then less collisions occur and the rate of reaction is decreased.
Similarly, concentration refers to the amount of substance present. The greater the amount of substance present, the greater the likelihood of collision between particles and the greater the rate of reaction and vice versa.
Number of proton in cesium is 55
To balance the redox equation in the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions are balanced separately by the number of electrons which accepted by reduction or donated by oxidation and then combined to give the balanced redox equation.
