of carbon and 16 g
of oxygen, what mass of carbon dioxide is formed?(1 point)
Responses

16 g

40 g

24 g

8 g

1 answer

According to the Law of Conservation of Mass, the total mass of reactants equals the total mass of products. In this reaction, we have:

  • Mass of carbon = 24 g
  • Mass of oxygen = 16 g

The total mass of the reactants is:

\[ 24 , \text{g} + 16 , \text{g} = 40 , \text{g} \]

This total mass will be equal to the mass of the carbon dioxide (CO2) formed. Therefore, the mass of carbon dioxide formed is:

\[ \text{Mass of CO2} = 40 , \text{g} \]

So the correct answer is 40 g.
