Answer :
Final answer:
When 12.7g of CO reacts with O2, it produces 12.7g of CO2, as the mass of the reactants equals the mass of the products following the law of conservation of mass. (a) 12.7g
Explanation:
The subject at hand seems focused on stoichiometry, a branch of chemistry which deals with the relative quantities and mass relations of reactants and products in a chemical reaction. The question asks, 'According to the given reaction, how many grams of CO2 could be produced from 12.7 g of CO and 12.7 g of O2?'
First, we need to consider the balanced equation of the reaction. For every molecule of CO that reacts with half a molecule of O2, one molecule of CO2 is created (CO + 0.5O2 => CO2). Therefore, assuming that there is no limitation by the ratio of reactants (i.e., no reactant is in excess or deficient), the same mass of CO and O2 will produce the same mass of CO2, considering the law of conservation of mass.
In the given scenario, the same mass (12.7g) of each reactant (CO and O2) is provided. Thus, according to the stoichiometric proportions of the balanced chemical reaction and the law of conservation of mass, 12.7g of CO2 will be produced. Hence, the answer to the question is (a) 12.7g.
