Answer:

[H⁺] = 1.0 x 10⁻¹² M.

Explanation:

∵ [H⁺][OH⁻] = 10⁻¹⁴.

[OH⁻] = 1 x 10⁻² mol/L.

∴ [H⁺] =  10⁻¹⁴/[OH⁻] = (10⁻¹⁴)/(1 x 10⁻² mol/L) = 1.0 x 10⁻¹² M.

∵ pH = - log[H⁺] = - log(1.0 x 10⁻¹² M) = 12.0.

∴ The solution is basic, since pH id higher than 7 and also the  [OH⁻] > [H⁺].

Rudiy27
In a voltaic cell there are two electrodes: anode and cathode.

On the cathode, the reaction that occurs is reduction, which means that the metal gains electrons.

On the anode the reaction is oxidation, which means that the metal loses electrons.

In this voltaic cell the reaction on the anode is:

Zn --> Zn 2+  + 2e-, i.e. option C.

True [87]

Answer: option C - The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell

Explanation:

Meiosis is also known as REDUCTIVE DIVISION, simply because a parent cell with diploid number of chromosome (46) is divided into four daughter cells with haploid number of chromosome (23)

Thus, ONLY option C correctly defines meiosis
