To solve this problem, we will apply the law of conservation of mass, which states that the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
The balanced chemical equation for the reaction between oxygen and carbon to form carbon dioxide is:
C + O2 → CO2
From the equation, we can see that 1 molecule of carbon reacts with 1 molecule of oxygen (O2) to produce 1 molecule of carbon dioxide (CO2). Therefore, the mole ratio between carbon and oxygen is 1:1.
Given that the mass of carbon is 24 g, we can determine the molar mass of carbon (C) by referring to the periodic table. The molar mass of carbon is 12 g/mol.
Since the mole ratio between carbon and oxygen is 1:1, the mass of oxygen (O2) required in the reaction will also be 24 g, as one mole of oxygen contains 2 moles of oxygen atoms (O2 has a molar mass of 32 g/mol).
Therefore, the mass of dioxygen (O2) in the reactants is 24 g.
Answer: B) 24 g
according to the law of conservation of mass, if 88 g of carbon dioxide (co2) is produced in a reaction between oxygen (o) and 24 g of carbon (c), what is the mass of dioxygen (o2) in reactants?
A ) 32 g
B ) 24 g
C ) 64 g
D ) 104 g
