Answer:
- <em><u>pH </u></em><u>= 9.73</u>
<u></u>
Explanation:
<em>pOH</em> is the negative logarithm of the molar <em>concentration</em> of<em> hydroxide ions </em>and pH is the negative logarithm of the concentration of hydronium ions.
The mathematical expression to determine pOH is:
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
Where [OH⁻] means the molar concentration of hydroxide ions.
Substituting:
<em>pH </em>and <em>pOH</em> are related by the equation:

Answer:
It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
Explanation:
Marble can be otherwise called metamorphic rock which is formed as a result of heat application on limestone and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.
Heterogenous mixtures are unevenly mixed. Like oil and vinegar in vinaigrette if it is not emulsified well enough and they separate. Any case where two things are not evenly distributed within each other.
Homogenous mixtures are evenly mixed throughout. Like salt water or kool-aid (when it's mixed).
