The average concentration of strontium ion in seawater is 8.00 mg of strontium ion per kg of seawater. What is the molarity of the strontium ion if the density of the seawater is 1.025 g/mL.
What is the percentage protonation of the solute and Calculate the pH of the solute in an aqueous solution of 0.611 M Aqueous solution of Ammonia
With respect to the corrosion of steel in concrete, explain the significance of the following terms: carbonation of concrete, passivity of steel, electrical resistivity of concrete, state of oxidation of iron.
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 10.0 torr at 35 °C. The vapor pressure of pure ethanol at 35 °C is 1.00 × 10^2 torr.
One metric ton (1000 kg) of coal is required to produce 7.3 MW-hr of electrical energy. In 1993, the Thomas Hill power plant (a small, coal-fired plant supplying rural electric cooperatives) produced 7100000.0 MW-hr.
