Answer:

Decomposition and redox  

Explanation:

2Ni₂O₃ ⟶ 4Ni + 3 O₂

This can be classed as a decomposition reaction, because a compound is decomposing into simpler substances.

It can also be classed as a redox reaction. The oxidation number of Ni decreases (reduction) from +3 in Ni₂O₃ to 0 in Ni, while the oxidation number of O increases (oxidation) from -2 in Ni₂O₃ to 0 in O₂.

Among the many types of reactions are:

  • Combination
  • Decomposition
  • Single displacement
  • Double displacement
  • Reduction-oxidation
  • Precipitation

Of the five salts listed below, which has the highest concentration of its cation in water? assume that all salt solutions are s
Zigmanuir [339]
First of all, I need to know what these five salts are. Luckily, I found a similar problem from another website which is shown in the attached picture. The Ksp is the solubility product constant. It follows the formula:

Ksp = [cation concentration]ᵃ[anion concentration]ᵇ
where a and b are the subscripts of the metal and nonmetal, respectively. 

For the solutions ahead, let x be the concentration of the cation.

A.  The formula is PbCr₂O₄.
2.8×10⁻¹³ = [x][x]
Solving for x, x = 5.29×10⁻⁷ M

B. The formula is Co(OH)₂. 
 1.3×10⁻¹⁵ = [x][x]²
Solving for x, x = 1.09×10⁻⁵ M

C. The formula is CoS. 
 5×10⁻²² = [x][x]
Solving for x, x = 2.24×10⁻¹¹ M

D. The formula is Cr(OH)₃. 
 1.6×10⁻³⁰ = [x][x]³
Solving for x, x = 3.56×10⁻⁶ M

E. The formula is Ag₂S. 
 6×10⁻⁵¹ = [x]²[x]
Solving for x, x = 1.82×10⁻¹⁷ M

<em>Thus,the highest concentration is letter B, Cobalt (II) Hydroxide.</em>
