A strange ion has been discovered! An oxygen atom with two positive charges! (O2+) Draw a picture of the old model of the atom (before the quantum mechanical model was developed). Use for + protons and - for electrons

A100-watt light bulb radiates energy at a rate of 100 j/s. (the watt, a unit of power or energy over time, is defined as 1 j/s.) if all of the light emitted has a wavelength of 525 nm , how many photons are emitted per second?

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?
