Many computer chips are manufactured from silicon, which occurs in nature as sio2 . when sio2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. in an industrial preparation of silicon, 155.3kg of sio2 of is allowed to react with 79.3kg of carbon to produce 66.2kg of silicon. what is the theoretical yield for the reaction in kg si? what is the percent yield for the reaction?

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

hope i !

i think its 100

i hope this !
