Explanation:

A balanced reaction is a reaction where there are equal number of atoms on both reactant and product side.

For example, 2C_{8}H_{18} + O_{2} \rightarrow CO_{2} + H_{2}O

Number of atoms on reactant side are as follows.

  • C = 16
  • H = 36
  • O = 2

Number of atoms on product side are as follows.

  • C = 1
  • H = 2
  • O = 3

Therefore, in order to balance the equation we multiply O_{2} by 25 on reactant side and multiply CO_{2} by 16 and H_{2}O by 18.

Thus, the balanced chemical equation will be as follows.

       2C_{8}H_{18} + 25O_{2} \rightarrow 16CO_{2} + 18H_{2}O

Igoryamba

Answer: F.    Electron pair acceptor

Explanation:

A Lewis acid can be properly defined as any substance such as  H+ (hygrogen ion) that can accept a pair of electron.

While a Lewis base is any substance such as (OH-) that can donate a pair of electron.

In the neutralization reaction between an acid ( H+ ) and a base (OH-). Hydrogen ion (H+ ) is the Lewis acid because it accepts an electron pair from (OH-).

Other examples of Lewis acid are;  Mg2+, K+
