<span>Answer:
Ground state of Hydrogen = -13.6 eV Energy of photon emission: E = hf = hc/λ = 6.6256E-34 (3E8)/680E-9 E = 0.0292E-17 J(1 eV/1.6E-19 J) = 1.825 eV E(photon) = 1.825 eV Bandgap energy: ΔE = E – Eo = 1.825 – (-13.6) = 15.425 eV</span>

Answer:
well tbh it's just the microwave doing its job heating up your Mac n cheese. But while doing so the Mac n cheese absorbs a lot of heat and then releases it by popping.
There are 8 oxygens if you multiply the 4 by the 2
I don’t know if this helps or not I’m still Not used to answering questions on Brainly These metals — beryllium, magnesium, calcium and strontium — react with hydrochloric acid to form a chloride and free hydrogen. Metallic magnesium when combined with hydrochloric acid, will naturally result in magnesium chloride -- used as a dietary supplement -- with the hydrogen being released as a gas.
