Based on the calculations, the solubility of mg(oh)₂ at a pH of 12.70 is equal to 3.4 × 10⁻⁵ M.
<u>Given the following data:</u>
- Ksp of mg(oh)₂ = 1.6 × 10⁻¹³
<h3>What is pH?</h3>
pH is an abbreviation for the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions that are present in a given solution. Thus, the power of hydrogen ions (pH) is generally used to identify or specify the acidity, neutrality, or basicity of any chemical solution.
First of al, we would write the properly balanced chemical equation for this chemical reaction:
Mathematically, the Ksp for the above chemical reaction is given by:
Ksp = [Mg²⁺][OH⁻]²
Ksp = [x][2x]²
1.6 × 10⁻¹³ = 4x³
x = ∛4 × 10⁻¹⁴
x = 3.4 × 10⁻⁵ M.

The option that most accurately describes your company's production operations is:
- Standard and superior materials are sourced from outside suppliers at "base" prices that are currently $6 per pair for 100% use of standard materials and $12 per par tor 100% use of superior materials, however, these base prices can vary up or down according to the strength of global demand for footwear materials and the global percentage usage of standard versus superior materials
<h3>What is the production operations?</h3>
Production and operations is said to be the management of works and operations that are said to be used by businesses in regards to production of their goods and services.
Hence the Standard and superior materials are sourced from outside suppliers at "base" prices that are currently $6 per pair for 100% use of standard materials and $12 per par tor 100% use of superior materials, however, these base prices can vary up or down according to the strength of global demand for footwear materials and the global percentage usage of standard versus superior materials

Answer:
Stroma, in botany, refers to the colorless fluid surrounding the grana within the chloroplast. Within the stroma are grana (stacks of thylakoid), and the sub-organelles or daughter cells, where photosynthesis is commenced before the chemical changes are completed in the stroma. Photosynthesis occurs in two stages.
