odium nitrite is manufactured based on the reaction represented by the following chemical equation: Na2CO3(s) + 2NO(g) + O2(g) → 2 NaNO2(s) + CO2(g) The Na₂CO3 used is first dissolved in water to form a 40% solution.

On a basis of 100 kg of Na₂CO3, calculate: a) the mass of NaNO2 obtained, b) the composition of the resulting solution (in mass percent), b) The composition of the issuing gas (in mole percent

The industrial production of nitric acid (HNO3) is a multistep process. The first step is the oxidation of ammonia (NH3) over a catalyst with excess oxygen (O2) to produce nitrogen monoxide (NO)gas as shown by the unbalanced equation given here: ?NH3(g)+?O2(g)→?NO(g)+?H2O(g) A) What volume of O2O2 at 722 mmHg and 25∘C is required to synthesize 11.0 mol of NO?

Problem #3 (35%) Vinyl chloride is synthesized through the following reaction of acetylene and hydrochloric acid: C2 H2+ HCl → CH2CHC The following undesired reaction also occurs simultaneously, producing dichlorethane instead: C2 H2 + 2HCI C2 H4CL2 - These reactions occur in a reactor during the manufacture of vinyl chloride. In this process, the feed to the reactor contains 100 Kmol/h of acetylene. The same feed also contains HCI, 16% in excess of that needed if the desired reaction went to completion, as well as 1.2 Kmol/h of an inert contaminant (water vapor). The single-pass fractional conversion of acetylene in the reactor is 12%, and 94% of the C2H2 so reacted is consumed in the first reaction to form vinyl chloride. The only stream leaving the reactor goes to a separation unit where all the vinyl chloride and all the dichlorethane are condensed and removed through a bottom liquid stream. This liquid stream contains nothing else. The top gaseous stream from the separator is…

A student wishes to determine the chloride ion concentration in a water sample at 25 °C using a galvanic cell constructed with a graphite electrode and a half-cell of AgCl(s) + e⁻ → Ag(s) + Cl⁻(aq) E°red = 0.2223 V And a copper electrode with 0.500 M Cu²⁺ as the second half cell Cu²⁺(aq) + 2 e⁻ → Cu(s) E°red= 0.337 V The measured cell potential when the water sample was placed into the silver side of the cell was 0.0647 V. Given the standard cell potential for this cell is 0.115 V, what is the value of the standard free energy (in kJ) for this reaction?

2. Ammonia reacts with oxygen to form nitric oxide and water: 4NH3 + 50₂ → 4NO + 6H₂O The fresh feed stream contains ammonia and oxygen, with the oxygen in 80.0% excess. The molar flow rate of the ammonia in the fresh feed stream is 200. mol/min. The conversion of the ammonia in the reactor is 65.0%. (a) Determine the number of degrees of freedom. Show your work. (b) Determine the molar flowrates of nitric oxide, oxygen, and water exiting the reactor. (c) To reduce the loss of the unreacted ammonia, the exit stream from the reactor is sent to a separation unit. Two streams leave the unit. One exit stream contains all of the ammonia and is recycled and combined with the fresh feed. The second exit (product) stream contains all of the nitric oxide, oxygen, and water. Draw the flowchart and label carefully. What is the overall conversion of the ammonia for this process? Is there sufficient oxygen in the fresh feed? Explain.
