A)Renewable Energy Sources
Explanation:
Contour interval. Noted on the map legend.
The answer is quartz where the hardness is 7.
Can scratch glass easily. This is where most granites are rated in terms of hardness
Yes, It is important to know the volume of Unknown acid or base to be titrated.
Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.
M₁V₁/n₁ = M₂V₂/n₂
