<p>106th question (T/F, T/F, CE type):
(I) Two liters of carbon dioxide can be produced by 1 gram of carbon burning completely, because (II) the amount of gas evolved in a chemical reaction can be determined by using the mole relationship of the coefficients in the balanced equation.</p>
<p>Statement II is undoubtedly true and is the correct explanation of I, if I is also true.</p>
<p>The question is: is really statement I true (as it is said in the book)? 1 gram of carbon burning completely produces 1.87 liters of CO2 (at STP, but there is no information about temp. or pressure). We need 1.07 grams of carbon to produce 2 liters of CO2. And so is the answer in the book. Please, explain me that. How is it possible? (i know, at other circumstances than STP it is, but if there are no other informations given i assume STP)</p>
