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.

Answer:
Cleaning products like bleach, oven sprays, liquid laundry capsules and toilet cleaners are chemicals. So are paints, glues, oils, pesticides and medicines. Most of the chemicals you use at home aren't dangerous if you use them properly. However, some chemicals need more careful handling than others.
The two molecules will only react if they have enough energy. By heating the mixture, you are raising the energy levels of the molecules involved in the reaction. Increasing temperature also means the molecules are moving around faster and will therefore "bump" into each other more often.
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
