Question

select the correct answer from the drop - down menu. if 56 grams of carbon monoxide burns in oxygen to produce 88 grams of carbon dioxide, the mass of oxygen involved in the reaction is grams. reset next

Explanation:

Step1: Apply law of conservation of mass

According to the law of conservation of mass, the total mass of reactants equals the total mass of products. Let the mass of oxygen be $x$. The reactants are carbon - monoxide and oxygen, and the product is carbon - dioxide. So, mass of carbon monoxide+mass of oxygen = mass of carbon dioxide.
$56 + x=88$

Step2: Solve for $x$

Subtract 56 from both sides of the equation: $x = 88 - 56$
$x = 32$

Answer:

32
