- please help answer questions 1-4 on paper thank you and this about kinetics and equilibrium unitIculating an equilibr composition after a prior equililbrium... "Synthesis gas" is a mixture of carbon monoxide and water vapor. At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially. A chemical engineer studying this reaction fills a s0 L tank with 18. mol of carbon monoxide gas and 23. mol of water vapor. When the mixture has come to equilibrium she determines that it contains 7.0 mol of carbon monoxide gas, 12. mol of water vapor and 11. mol of hydrogen gas. The engineer then adds another 5.0 mol Of carbon monoxide, and allows the mixture to come to equilibrium again. Calculate the moles of carbon dioxide after equilibrium is reached the second time. Round your answer to 2 significant digits. mol Ox10Explain how the distribution of kinetic energies of the molecules in a sample is affected by: the use of a catalyst in a chemical reaction an increase in temperature in a chemical reaction
- According to Wikipedia, Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. 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…Molecular collisions may or may not lead to a chemical reaction between Cl and NaCl.
