- Gold is produced electrochemically from an aqueous solution of Au(CN)2 containing an excess of CN. Gold metal and oxygen gas are produced at the electrodes. What amount (moles) of O2 will be produced during the production of 1.00 mole of gold?In an experiment, sulfuric acid reacted with different volumes of sodium thiosulfate in water. A yellow precipitate was formed during the reaction. A cross drawn at the base of each flask became gradually invisible due the formation of this yellow precipitate. The time taken for the cross to become invisible was recorded. A partial record of the experiment is shown.

Use complete sentences to explain the trend you predicted. You do not have to determine exact values for time; just describe the trend you would expect (increase or decrease) and why it occurs.Ten replicate analyses of the concentration of mercury in a sample of commercial gas condensate gave the following results:23.3 22.5 21.9 21.5 19.9 21.3 21.7 23.8 22.6 24.7 ng ml−1

The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that carbon- 14 is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting carbon-14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire carbon-14 by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of carbon-14 it contains begins to decrease as the carbon-14 undergoes radioactive decay. Measuring the amount of carbon-14 in a sample from a…ebixoiC 4 During the production of ammonia, hydrogen is produced from the steam reforming of methane.

- When calcium oxalate monohydrate is heated, anhydrous calcium oxalate and water are formed. Further decomposition of the calcium oxalate produces calcium carbonate and carbon monoxide. If the heating temperature is increased to well above 600 degrees celsius, calcium carbonate will decompose to calcium oxide and carbon dioxide.

- Nitroglycerin (C3H5N3O9) is a powerful explosive. Its decomposition may be represented by 4C3H5N3O9 ⟶ 6N2 + 12CO2 + 10H2O + O2 This reaction generates a large amount of heat and many gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion. (a) What is the maxi- mum amount of O2 in grams that can be obtained from 2.00 × 102 g of nitroglycerin? (b) Calculate the percent yield in this reaction if the amount of O2 generated is found to be 6.55 g.49.4 g of CaCO3 (s) reacts with 878 mL 1.8 M HCI (aq).
