Question

Which of the following statements are true? Which are false? Why is each true or false?

(e) When steam at 100°C in an autoclave is heated to 120°C, the pressure within the autoclave Increase.

(f) When using the ideal gas law for calculations, temperature must be in degrees Celsius.

Definition Definition Law that is the combined form of Boyle's Law, Charles's Law, and Avogadro's Law. This law is obeyed by all ideal gas. Boyle's Law states that pressure is inversely proportional to volume. Charles's Law states that volume is in direct relation to temperature. Avogadro's Law shows that volume is in direct relation to the number of moles in the gas. The mathematical equation for the ideal gas law equation has been formulated by taking all the equations into account: PV=nRT Where P = pressure of the ideal gas V = volume of the ideal gas n = amount of ideal gas measured in moles R = universal gas constant and its value is 8.314 J.K-1mol-1 T = temperature

Osmotic pressures are often reported in units of atmospheres or mm Hg. The latter impliesthat the height of a column of liquid can be used as a measure of pressure. This is, in fact, thebasis of the torricellian barometer from which the units of “torr” come. The pressure, P, isrelated to the height of the column by:P = ρghwhere ρ is the density of the liquid, g is the acceleration due to gravity and h is the height. Whatwill be the height (in mm) of a column of aqueous solution with a density of 0.9987 g/mL, if theosmotic pressure of the solution at 25 °C is 1.4 mm Hg? The density of mercury at thistemperature is 13.8 g/mL
A water contains 50.40 mg · L−1 as CaCO3 of carbon dioxide, 190.00 mg · L−1 as CaCO3 of Ca2+ and 55.00 mg · L−1 as CaCO3 of Mg2+. All of the hardness is carbonate hardness. Using the stoichiometry of the lime soda ash softening equations, what is the daily sludge production (in dry weight, kg · day−1) if the plant treats water at a rate of 2.935 m3 · s−1? Assume that the effluent water contains no carbon dioxide, 30.0 mg · L−1 as CaCO3 of Ca2+ and 10.0 mg · L−1 as CaCO3 of Mg2+. Be sure to calculate the mass of CaCO3 and Mg(OH)2 sludge produced each day.
