If a 0.2800g sample of sodium bicarbonate (96.5% NaHCO3) is titrated with 0.9165N Sulfuric acid, what volume of the acid should be required to produce an end point?

A solution containing sodium fluoride is mixed with a solution containing cadmium nitrate to form a solution that is 0.0050 M in NaF and O.00250 M in Cd(NO3)2. If the Ksp for CDF2 is 6.44x10-3, then Q > K and a precipitate of CDF2 will form. O Q < K and more CDF2 will precipitate since the solution is not supersaturated. O Q < K and CdF2 does not precipitate. Q = K and the system is at equilibrium.

Sunflower oil contains 0.090 mol palmitic acid (C₁6H3202)/mol, 0.060 mol stearic acid (C₁8H360₂)/mol, 0.36 mol oleic acid (C₁8H340₂)/mol, and 0.49 mol linoleic acid (C₁8H32O₂)/mol. To create margarine from sunflower oil, the liquid oleic and linoleic acids are hydrogenated in the presence of a metal catalyst to form solid stearic acid. C18H34O2 + H₂ →→ C18H3602 - C18H32O2 + 2H₂ → C18H3602 At a margarine production facility, a stream of 305.0 mol sunflower oil/h is fed into a reactor. The fresh hydrogen source available is a mixture containing 0.97 mol H₂/mol and 0.030 mol N₂/mol. N₂ is inert in this process. To ensure complete hydrogenation, the hydrogen gas mixture is introduced into the reactor in 55.0% excess. All reaction products leave the reactor and proceed to a separator where palmitic and stearic acids are separated from the hydrogen gas mixture. The hydrogen gas mixture is recycled to the fresh feed stream, and 105.0 mol gas/h of this recycle stream is purged to prevent the…

3. Carbon tetrachloride (CC14) can be produced using the following reaction. If 34.535 grams of chlorine (Cl2) produced 28.550 g of CC14, what is the percent yield of this reaction? C(s) + 2 Cl2(g) CCI4(1)

15.00 ml of a 0.3400 m manganese(iii) acetate solution is mixed with 25.00 ml of a 0.2311 m ammonium carbonate solution. Calculate the number of grams of solid precipitate produced. Calculate the molarity of all species in solution after the reaction has taken place.

calculate the fraction (using fractional composition equation), for all three with a molar concentration of 0.04M a) H2S, pH= 4.21 b) NaHS pH= 9.8 c) Na2S, pH= 12.58

1. On the following page, construct a graph of n'H, (moles hydrogen per gram of sample) vs. % Al. Use Equation (12): (100-%A¹(0.0153) (A)(0.0556)+( H₂ Simply solve this equation for n'H, using % Al = 0 and % Al = 100, then draw a straight line through these points. n H₂ = % (12)

Consider an aerobic production of acetic acid (P) from ethanol (S) using Acetobacter aceti bacteria. Acetobacter aceti bacteria are added to vigorously-aerate medium containing 16 g/L ethanol. 3 g/L acetic acid is produced after 10 hours . Given the yield coefficient (YS/P) of 1.5, what is the concentration of ethanol after 10 hours ? Report your answer with two decimal places.

Using the provided ternary phase diagram 1) Determine the EXACT composition of point a2. 2) Determine the maximum amount of (in moles) of pure E that can be added to a 10 mol mixture at point a2 to maintain a two-phase system?
