MariettaO [177]

Answer:

The correct option is d: carbon and oxygen.

Explanation:

The reaction between carbon and oxygen to form carbon dioxide is:

C + O₂ → CO₂    (1)

 

On the left side of the above reaction (1), we have the reactants, which are carbon (C) and oxygen (O₂) that react to form carbon dioxide (CO₂), which is the only product of the reaction (on the right side of the reaction).      

     

Hence, the correct option is d: carbon and oxygen.

I hope it helps you!

Tate the law of conservation of mass. Then apply the law to this question: What would be the total
Savatey [412]
<span>The law of conservation of mass states that, "Mass can neither be created nor destroyed, only its form changes with respect to different forms of energy." In any reaction, say 10 gms of water is decomposed into its constituents Hydrogen and Oxygen. But the mass remains conserved for the reaction. Although mass and energy are inter-convertible. But,the net mass/energy remains conserved i.e. the mass of products will be equal to the mass of reactants. </span>
