The pH in a lake the size of 4.0 km X 7.0 km and an average depth of 100 m is found to be 4.5. Calculate the mass of calcium carbonate that must be added to the lake water in order to raise its pH to 6.0, assuming the reaction of H+ with CaCO3 gives CO2 here (answer in grams).
Hint: Calculate volume of lake, change of H+ concentration, mol of calcium carbonate required.
A cylinder is separated into two sections Y and Z by an insulating frictionless piston and sealed at both ends. Each section has two moles of an ideal gas.
Differ from the ideal pressure? The value For N 2 gas is given as , a = 1.390 L2atm/mol2 and b = 3.910E-2 L/mol.
Please review the occurrence and cycling of calcium in nature, along with its use. Analyze and evaluate the article as to it's contemporary relevance regarding the elements availability, health implications and environmental impact.
