Answer 1

You will end up with 5g of carbon

Step-by-step explanation:

If one starts a reaction with 5g of carbon, they will end up 5g of carbon at the end of the reaction.

Chemical reactions obey the law of conservation of mass.

• Based on this law "mass is always conserved as matter is neither created nor destroyed in a chemical reaction".
• Therefore, whatever the reactants we start with, we end with the same amount.
• Though species recombine to give a different compound in the product, the mass is still always conserved.
