Consider the combustion reaction for octane (C8H18), which is a primary component of gasoline.
lesya692 [45]

Answer:

n_{CO_2}=1.93 gCO_2

Explanation:

Hello,

In this case, considering the given chemical reaction, we can use the molar mass of octane (114.23 g/mol) and the 2:16 molar ratio with carbon dioxide to compute the emitted moles of CO2 to the atmosphere via the following stoichiometric procedure:

n_{CO2}=27.6gC_8H_{18}*\frac{1molC_8H_{18}}{114.23gC_8H_{18}}  *\frac{16molCO_2}{2molC_8H_{18}} \\\\n_{CO_2}=1.93 gCO_2

Which also corresponds to the following mass:

m_{CO_2}=1.93molCO_2*\frac{44gCO_2}{1molCO_2} \\\\m_{CO_2}=85.0gCO_2

Best regards.

Which of these chemical formulas kci, xe, co2, or h2- represents both an element and a molecule?
Temka [501]
An element is a substance that can not be broken into simpler parts by chemical means. Elements are made up of atoms. A molecule is the smallest particle of an element or a compound that has the same properties as the element or the compound. A molecule is made up of two or more atoms . A substance may be an element and a molecule. In this case the answer is, H2 (hydrogen gas) which is a molecule with two atoms of hydrogen and an element.
