Answer:
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.

:)
In the modern periodic table the elements are arranged in order of increasing atomic number.
In which elements are belonging to? I will grant that option B ; ti's the best answer.
In which thou might contain the elements zinc , gold , aluminium , and last by not least oxygen.
I truly hope ti's answer helps thou.
Answer:
Zn + 2 HCl → ZnCl₂ + H₂
Explanation:
We have to complete this single replacement reaction.
Zn(s) + HCl(aq) →
We need to decide if Zn will replace H⁺ or Cl⁻. Zn can form the cation Zn²⁺ but it does not have a negative oxidation number to form an anion. As a consequence, the cation Zn²⁺ will replace the cation H⁺ to form ZnCl₂. H₂ will be released as a gas.
Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g)
