What mass of carbon monoxide is produced when 1.50 moles of oxygen react completely in the following equation? 2C + O₂ → 2CO

The answer to your question is 3 moles of CO

Explanation:

Data

mass of CO = ?

moles of O₂ = 1.50

Balanced chemical reaction

                  2C + O₂ ⇒  2CO

Process

To solve this problem use proportion and cross multiplication. Use the coefficients of the balanced equation.

                     1 mol of oxygen 2 moles of CO

                      1.5 moles of oxygen  x

                       x = (1.5 x 2) /1

-Simplification

                       x = 3 / 1

-Result

                       x = 3 moles of CO

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
