If 27.3 grams of NaClO3 are heated, how many liters of O2 would you expect to be formed? 2 NaClO3(s) + heat → 2 NaCl(s) + 3 O2(g) (Find moles of NaClO3 . Mole ratio to find how many moles of O2. Multiply those moles by 22.4 L for final volume.)

One does not belong why? ice, gold ,wood ,diamond and table salt

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
