A 6.50-g sample of a diprotic acid requires 137.5 mL of a 0.750 M NaOH solution for complete reaction. Determine the molar mass of the acid. Additionally, citric acid, which can be obtained from lemon juice, has the molecular formula C6H8O7. A 0.250-g sample of citric acid dissolved in 25.0 mL of water requires 37.2 mL of 0.105 M NaOH for complete neutralization. What number of acidic hydrogens per molecule does citric acid have?
Design the manufacture of (tones/day) Ferrous sulphate monohydrate from waste pickle liquor. Pickling is generally associated with the removal of scale with mineral acid. Sulphuric acid is the most commonly used pickling acid.
the rate of flow to an ammonia synthesis reactor contains 25 mole ltbrgtnitrogen and the balance hydrogen. the flow
Describe issues to be considered when developing an evacuation procedure to help ensure the safe evacuation of employees and visitors in the event of a fire Outline the benefits of undertaking regular fire drills in the workplace
An analyst gathered the following information about the return distributions for two portfolios during the same time period:
Compute the increase in temperature and entropy if saturated liquid water at 10 kPa is pumped to a pressure of 9.0 MPa, if the pump is 75% efficient (where 100% efficiency would be reversible). You may use constant values and at these conditions.
In the direct steelmaking reactor based on the reduction of an oxidizing foaming slag by char (carbon) particles and droplets of iron containing 2% carbon. Estimate the total surface area of char and iron droplets needed to achieve the smelting ..
Prepare a piping diagram and calculate the pipe size as well as the required power of the pump. You need to specify the type of fittings and the pipe material for your calculations.
Determine the acceleration potential (in Volts) that must be applied to electrons so that in an electron diffraction experiment of {200} planes of silver, Ag, they will result in first order diffraction at 2?
Determine the longest wavelength (in cm) of X-rays that is still capable of producing diffraction in copper, Cu.
Carbon dioxide can be separated from other gases by preferential absorption into an amine solution. The carbon dioxide can be recovered by heating at atmospheric pressure. Suppose pure CO2 vapor is available from such a process at 80°C and 1 bar. Sup..
Consider that you are a senior consulting engineer and that you need to explain the topic in a written report to your customer, who is the managing director of a large company, and a commerce or law graduate.
Derive an equation for the latent heat of fusion that is a function of the radius of the particle. Using this equation, for a copper particle that has a radius of 2.5 nm, find the ratio of the latent heat of fusion of the particle to the laten..
