What is an energy level?​

Certain types of organisms such as fireflies and anglerfish can produce light through chemical reactions in a process called bioluminescence. what kind of chemical reactions occur during bioluminescence? o a) exothermic ob) endothermic oc) recomposition od) decomposition

Identify the missing coefficient in the balanced equation and classify the type of reaction. mg(oh)2 + h2so4 ⟶ mgso4 + 1; combustion 1; neutralization 2; combustion 2; neutralization

Electron configurations are a shorthand form of an orbital diagram, describing which orbitals are occupied for a given element. for example, 1s22s22p1 is the electron configuration of boron. use this tool to generate the electron configuration of arsenic (as).
