The product in this chemical reaction is Carbon Dioxide or CO2.
This is because it states, "To form," which means that it was produced from the reactants Carbon and Oxygen.
To know what the products are in a statement rather than an equation, words such as produced and formed are used.
Hope this helps!
The change in energy level is equivalent to the energy of the released photon. This is related by Planck's equation:
E = hcf
The higher the energy change, the greater the frequency, f, of the photon.
Because it has molecules of water in it
It would have filtered already within the time frame of 2 to 3 hours because of the molecular injection ignited by the co2 within the strip so you would observe the UNDERSIDE OF THE PAPER and the molecular tear within it
