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.

The second one, vocab and definition doesn't add up
Answer:
Explanation:
Hello,
In this case, we can apply the Boyle's law in order to understand the pressure-volume relationship as an inversely proportional relationship relating the initial and the final volume:
Next, we compute the final pressure P2:
Thus we validate, the higher the volume the lower the pressure.
Best regards.
Answer:
A. Law of constant composition or definite proportion
B. Law of conservation of mass
C. Law of multiple proportion
Explanation:
A. The law of constant composition states that "all pure samples of the same chemical compound contain the same proportion of the elements by mass". Considering the pure same of KCl obtained from different locations, their samples regardless of the procedure used to make them or geography wil be in the same proportion when analysed.
B. Law of conservation of mass states that "mass can neither be created nor destroyed". This law applies to all chemical reactions in which matter is only changed from one form to another. In the bulb, magnessium and oxygen merely combines to magnessium oxide. No loss of matter.
C. Law of multiple proportion states that "when two elements combine to form two or more different compounds, the masses of one of the elements which seperately combine with a fixed mass of the other element are in a simple ratio ".
