Thermosphere: 80 to 700 km (50 to 440 miles)
Mesosphere: 50 to 80 km (31 to 50 miles)
Stratosphere: 12 to 50 km (7 to 31 miles)
Lowest: Troposphere: 0 to 12 km (0 to 7 miles)
Explanation:
That statement is true
Despite its cheap price, The usage of coal as an energy source will release <span>sulfur dioxide, nitrogen oxides, to the air around our environment.
This substance will give negative effects such as acidic rain that could be corrosive to our body and polluted air that is bad for our respiratory system.</span>
The number of moles of each atom present in 5 moles of Cu₃(PO₄)₂ are:
- 15 moles of Cu
- 10 moles of P
- 40 moles of O
<h3>Description of Cu₃(PO₄)₂</h3>
- 1 mole of Cu₃(PO₄)₂ contains
- 3 moles of Cu
- 2 moles of P
- (2×4) = 8 moles of O
<h3>How to determine the mole of each atom </h3>
The moles of atom present in 5 moles of Cu₃(PO₄)₂ can be obtained as follow
<h3>For Cu</h3>
1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 3 = 15 moles of Cu
<h3>For P</h3>
1 mole of Cu₃(PO₄)₂ contains 2 moles of P.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 2 = 10 moles of P
<h3>For O</h3>
1 mole of Cu₃(PO₄)₂ contains 8 moles of O.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 8 = 40 moles of O
