The answer for this would be 69.6
Answer: 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal
Explanation:
To calculate the moles :
The balanced chemical equuation is:
According to stoichiometry :
4 moles of
produce == 2 moles of
Thus 0.556 moles of
will produce=
of
Mass of
Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.
Loudness of the sound depends on the "Amplitude" as loudness is different for two waves, their Amplitude must be different
In short, Your Answer would be "Amplitude"
