The balanced reaction that describes reaction of ethylene and oxygen to produce carbon dioxide and water is expressed C2H2(g) + 5/2 O2 (g) = 2cO2 (g)+ h2O(g). We convert first the given data to moles thru PV=nRT. The number of moles of oxygen is 0.6349 moles. One mole of c2h2 reacts with 2.5 moles oxygen. The answer is 0.2539 moles c2h2.

Which of the following is NOT true about relative dating?
Igoryamba

Answer:

It uses fossils to help pinpoint the ages of rocks.

Explanation:

Radiocarbon  dating can not be used  to determine the age of rocks.

Carbon dating works well only for objects that are less than 50,000 years.  Most rocks are far older than that. Over time, carbon-14 decays gradually  into nitrogen. Hence, we can not really use radiocarbon dating to determine the absolute age of a rock sample since the carbon-14 in the fossils of ancient rock samples may have completely decayed.
