Think about the decomposition reaction of ozone.
____ [38]

Answer:

3441.6 grams.

Explanation:

2 O₃ → 3 O₂

First we <u>convert 71.7 moles of ozone (O₃) into moles of oxygen gas (O₂)</u>, using the <em>stoichiometric coefficients</em> of the reation:

71.7 mol O₃ * \frac{3molO_2}{2molO_3} = 107.55 mol O₂

Then we <u>convert 107.55 moles of O₂ into grams</u>, using the <em>molar mass of O₂</em>:

107.55 mol * 32 g/mol = 3441.6 g

brilliants [131]

Answer:

The correct answer is - They are mechanical waves.

Explanation:

Atomic bombs after detonated they send a shock wave that makes a movement of particulate matter that leads to transfer of a high amount of energy that superheats the air medium that travels as a mechanical shock wave.

The shock wave that is sent out by a detonated atomic bomb is a longitudinal mechanical wave that transfers the energy to the neighboring particles of the air.
