Hi! I'm not 100% sure about my first three answers, and I don't known how to do the last question. Thank you for your help!

Barium sulphate forms as a precipitate in the following reaction: Ba(NO3)2 + Na2SO4 = BaSO4 + 2NaNO3 When 35g of Ba(NO3)2 is reacted with excess Na2SO4, 27.1g of BaSO4 is recovered by a chemist a) Calculate the theoterical yield of BaSO4 b) Calculate the percentage yield of BaSO4 c) Calculate the percentage error

How much iron oxide (Fe2O3) is needed to make a 500 mg fuel rich mixture of aluminum (Al) and iron oxide that has an equivalence ration of 1.3? What is the actual F/O ratio for this mixture?   Please provide only typed answer solution no handwritten solution needed allowed

Why is it necessary to provide a temperature with the value of Kc when doing a report?

Molten iron and carbon monoxide are produced in a blast furnace by the reaction of iron(lI) oxide and coke (pure carbon). The reaction is: Fe203 + 3 C ---> 2 Fe + 3 CO If 25.0 kilograms of pure Fe203 is used, how many kilograms of iron can be produced? Paragraph В I U v A + v の EQ Lato (Recom... 19px ...

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

For the following reaction, CO(g) H₂O(g) →CO₂ (9) a. Write the Kc expression for this reaction. b. If a 1.00L vessel is charged with 0.250 moles of CO, 0.250 moles of H₂0, 0.750 males of CO₂, and 0.750 males of H₂, what is the value of Q? + H₂ (9) Kc = 1.845 c. In which direction does the reaction progress to establish equilibrium? d. What are the equilibrium concentration of all species?

M Review | Constants | Periodic Table Titanium occurs in the magnetic mineral ilmenite (FeTiO3), which is often found mixed up with sand. The ilmenite can be separated from the sand with magnets. The titanium can then be extracted from the ilmenite by the following set of reactions: FeTiO3 (s)+3Cl,(g)+3C(s)→3CO(g)+FeCl, (s)+TIC1, (9) TICL (9)+2Mg(s)–2MgCl,(1)+Ti(s) Suppose that an ilmenite-sand mixture contains 20.0 % ilmenite by mass and that the first reaction is carried out with a 92.0 % vield. Part A If the second reaction is carried out with an 85.0 % yield, what mass of titanium can be obtained from 1.00 kg of the ilmenite-sand mixture? Express your answer with the appropriate units.

For the following reaction:        C3H8(g) +     O2(g)  ------>   CO2(g)   +     H2O(g) Q:  Calculate the theoretical yield of CO2(g) in gram

A cork popper. To entertain children between the ages of 22 and 90, Daniel Harris enjoys popping corks from bottles containing vinegar and baking soda. He pours about 50 mL of vinegar into a 500‑mL plastic bottle. Then, he wraps about 5 g of baking soda (which is sodium bicarbonate, NaHCO3) in one layer of tissue and drops the tissue into the bottle. He places a cork tightly in the mouth of the bottle and steps back. The chemical reaction generates CO2(g) that pressurizes the bottle and eventually bursts the cork into the air.
