We are given with a vinegar with a hydrogen ion concentration of 0.00010 m. We are asked to express this concentration in scientific notation. The answer when expressed in scientific notation is 1x10^-4 m or molality. Answer is <span>1x10^-4 m. </span>
Answer:
Answer is given below.
Explanation:
<em />
<em>Alkalinity = 400 mg/L in terms of CaCO3 </em>
<em>a.) Total Hardness is defined as the sum of calcium and magnesium iion concentration in terms of CaCO3
</em>
<em>
</em>
<em>Total Hardness = [Ca+2]*{50/20) + [Mg+2]*{50/12) = [200]*{50/20) + [60]*{50/12) = 750 mg/L in terms of CaCO3
</em>
<em>
</em>
<em>b.) Non-Carbonate hardness = Total Hardness - Carbonate Hardness
</em>
<em>
</em>
<em>Now here as the Total Hardness is greater than alkalinity ,Thus
</em>
<em>
</em>
<em>Carbonate Hardness = Alkanlinity = 400 mg/L in terms of CaCO3
</em>
<em>
</em>
<em>Non-Carbonate hardness = 750 - 400 = 350 mg/L in terms of CaCO3
</em>
<em>
</em>
<em>c.) As Total hardness is greater than Alkalinity thus Carbonate hardness is equal to the Alkalinity.
</em>
<em>
</em>
<em>Carbonate hardness = 400 mg/L in terms of CaCO3
</em>
<em>
</em>
<em>d.) Now as the Total hardness of the ground water is more than 180 mg/L,Thus it needs removal of hardness.
</em>
<em>
</em>
<em>There are many treatment options for the removal of hardness:
</em>
<em>i) Ion Exchange method
</em>
<em>ii) Lime soda method</em>
Answer:
Explanation:
Igneous rocks form on Earth’s surface where magma reaches the surface.
Igneous rocks form within Earth’s mantle where magma is typically found.
